Jeep Grand Cherokee Capless Gas Tank Problems

In May 2015, Jeep released its all-new 2016 Grand Cherokee. The release date happened to coincide with the release of the 2015 model year of many automakers including Ford, Honda, and Toyota. One of the design changes that came with this new vehicle was a hidden cap on the fuel tank which prevented extra fuel from spilling out in case of a rear-end collision.

1. The Fuel Nozzle Becomes A Dirt Magnet

What was the biggest problem with this new system? Well, for one thing, as soon as you fill-up the tank and close it, all of the dirt that collects around it would be sucked into the fuel system. This can cause a clog in the line or cause a leak which could eventually lead to a complete failure of your vehicle’s fuel pump.

2. A Bad Fuel Pump Is An Instant Issue

And unlike most vehicles that use a gas cap, Jeep decided to make its own. The cap that comes with this vehicle is an auto-locking system which means that you cannot use your typical replacement gas caps.

This means that if you were to lose your cap, you would be forced to purchase one directly from the manufacturer. Not only are they expensive, but they are hard to find and can only be obtained if you have the VIN number for both the car and the key fob.

3. Gas Nozzle Gets Stuck

But what happens if you don’t have the key fob with you? That’s where you will run into another problem. Once your tank is full, the nozzle becomes stuck inside of it and there is no external way to get it out.

You would have to take your vehicle over to a Jeep or Chrysler dealership and pay them a $100+ diagnostic charge just to get the fuel nozzle out of your tank which could be just a few ounces shy of $10,000 in gas.

4. Cashier’s Check Does Not Work

If you are not able to get the nozzle out of your tank, you will have to have it replaced by a dealership before you can fill it up again. While this isn’t really a problem for car owners with good credit, for those without it it can be a real hassle.

Not only does it require that you drive your car over to the dealer, but the technicians at most dealerships will not be able to use cash as payment and must rely on credit cards.

5. Repair Costs

So let’s say that you do go to the dealership, they replace the fuel nozzle and you drive away with a full tank of gas. What could go wrong? Well, once again you are relying on a defective part.

While some Jeep dealerships will have the capability to fix this part, some may not be able to and will require that they order it from Chrysler. This means that you would have to pay for a new nozzle again if your dealership is unable or unwilling to fix it themselves.

6. Opening The Tank Can Get Quite Hard

One of the worst parts about this hidden tank is that it makes it difficult for you to access your gas. It is a permanent fixture, so you cannot open and close it as easily as you could a normal gas cap. In fact, getting the tank to open once it has been closed can be quite challenging. You will have to spend at least five minutes fighting with your car door before you can actually access the fuel nozzle.

7. Scraps and Dirt  Collect On The Capless Fuel Filler

What we can find in most new vehicles is that the cap has a small drain hole in it which allows you to easily clean the fuel needle which is attached to it. This helps ensure that no extra gas can seep into your tank while you are driving.

What happens instead is that all of your dirt and oil will collect on this needle and make it difficult to seal properly. From there, the fuel will leak which could eventually lead to a complete failure of your fuel pump.

How to Fix Capless Gas Tank Problems in Jeep Grand Cherokee?

So what are you doing if your Jeep Grand Cherokee is causing problems with your gas tank? You’re not alone, and there is a solution.

1. Use Compressed Air To Clean Around The Gas Tank

If you want to clean your gas tank, then there is an easy way of doing this without having to remove it. This will allow you to get to every part of the tank and it is also going to ensure that you don’t leave any debris that might jam your fuel pump or cause other issues with your vehicle.

You will need a can of compressed air, so visit the local office supply store and get one if needed. Then follow these instructions on how to clean the area around your Jeep Grand Cherokee’s gas tank.

2. Purchase a Corrosion Protection Lubricant Spray

If you want to keep your fuel system in good order and it is going to be exposed to salt and other harmful elements, then you would absolutely need one of these types of spray.

We recommend the CRC Automotive Fuel System Corrosion Protection Spray which is specifically designed for this purpose. It is made from high-quality ingredients like anti-corrosive detergents, anti-oxides, and other additives that are designed to keep your gas tank clean and in top current condition.

3. Change The Gas Pump Nozzle

If you are serious about your fuel system and you want to avoid the issues discussed on this page, then we would recommend getting an upgraded gas pump nozzle. This can be installed in place of your current pump and it is going to be a bit more secure than the factory one.

It features a better locking mechanism and superior strength so that it will not crack or break like your old one will. This is a great investment for long-term use as it is going to prevent gas from leaking out of your vehicle at any point in time.

4. Gas Cap Replacement

The first thing you should do is get yourself a gas cap replacement kit. This means that you will be able to replace the existing cap on your tank yourself, instead of having a dealership do it for you. These kits are quite simple and easy to install, but they don’t come cheap. They will cost you about $50-$70 and can be found on Amazon.

How to Install the Gas Cap Replacement Kit:

1. Place the cap on top of your fuel tank and make sure that it fits snuggly in place.

2. Cut a piece of tubing that is slightly shorter than the length of the fuel line. You will be using this piece to fit down into your gas tank and then back up through the cap.

3. Take the tubing and slide it down into the fuel tank. The tubing should sit on top of your gas tank securely, but not too tightly to prevent air from traveling through it.

4. Now that the cap and tubing are in place, you can now run your vehicle until the cap is up to pressure. Once pressure is built up and the cap becomes tight to remove, tighten it using your hand so that it is secure in place. 
5. Slide the tubing out of the cap and make sure that it didn’t crimp. If it did, you will have to get a new piece of tubing and start over.

5. Customs Exhaust Systems

One of the best ways to avoid these issues is to use a custom exhaust system made specifically for the Jeep Grand Cherokee. These systems are designed to work with the hidden gas tank, and they are going to increase your power output as well. There are many different manufacturers that offer these systems and they start at around $1,000.

1. Ensure you have the right level at the top of your tank and don’t exceed it. You should fill up to around one inch below the rim and no more than 1 ¼”.

2. Now take a funnel or fuel bottle and put it over the gas cap and squeeze some gas into it. You should then put it on top of your fuel tank, but do not fully close the filler neck just yet.

3. Close the filler neck to a small enough level, then slowly and carefully pull it off of the tank. With your hand, push down until the gas reaches your cap. You should then pull it back off of the hose and repeat the process until you get all of the gas into your tank.

4.  Wait at least an hour before filling up again as you want a chance to let all of the air out of your system when you do this next time.

5. Replace your gas cap after you are done filling up and you are ready to go. If you get a new capless tank, then you will want to install the proper cap on it.

6. If you need additional help, then we have written a guide on how to fill up your Jeep Grand Cherokee. This will give you all of the information that you need, so read it for a better understanding of how the process works.

Jeep Grand Cherokee’s Capless Gas Tank Problems

The capless gas tank is a feature that allows you to fill up your tank without having to remove the cap. However, many people have found that this feature can cause problems.

One of the main issues with the capless gas tank is that it can leak. If there is any debris or dirt on the opening of the tank, it can prevent the seal from forming correctly. This can cause fuel to leak out, which can be dangerous and expensive.

Another problem with the capless gas tank is that it can be difficult to fill up. If you don’t have a good seal, air can get into the tank and prevent fuel from flowing incorrectly. This can make it take longer to fill up your tank and waste time and money.

If you’re experiencing problems with your capless gas tank, there are some things you can do to try to fix it. First, make sure that the opening of your tank is clean and free of any debris or dirt. If there is anything blocking the opening, try to remove it so that the seal can form properly.

You should also check the O-ring seals around the opening of your tank. These seals help to create a tight seal between the lid and the body of your tank. If they are damaged or worn out, they may need to be replaced.

You can buy replacement O-rings at most auto parts stores. Finally, if you’re still having trouble, you may need to take your car into the mechanic for further diagnosis and repair.

2018 Jeep Grand Cherokee Gas Filling Problems

If you own a 2018 Jeep Grand Cherokee, you may have noticed some problems when filling up your gas tank. Some owners have reported that the filler nozzle keeps shutting off, or that the pump takes a long time to fill up the tank. These problems can be caused by a few different things.

First, make sure that you’re using the right type of gas for your Jeep. The 2018 Grand Cherokee requires unleaded regular gasoline with an octane rating of 87. If you’re using a lower-octane gas, that could be causing the filling problems.

Another possibility is that your gas cap is not tight enough. The cap needs to be screwed on tightly in order for the pump to work properly. If it’s not screwed on tightly enough, air can get into the tank and cause the pump to shut off prematurely.

Finally, there could be an issue with the fuel gauge itself. If it’s not reading correctly, it could cause the pump to shut off before the tank is actually full. If you’re having any of these issues, take your Jeep to a certified dealership service center for diagnosis and repair.

The Jeep Grand Cherokee Gas Pump Keeps Stopping

If you own a Jeep Grand Cherokee, you may have experienced the frustration of your gas pump stopping while you’re trying to fill up. This can be a real pain, especially if you’re in a hurry. There are a few things that can cause this problem.

One possibility is that the fuel tank is not ventilated properly. When the tank isn’t vented, the pressure inside builds up and can cause the pump to shut off. Another possibility is that the fuel neck gasket is damaged or missing.

This gasket seals the connection between the fuel tank and the filler neck. If it’s damaged, it can allow air to get into the tank, which also causes pressure to build up and can make the pump shut off. The good news is that both of these problems are relatively easy to fix.

If your tank isn’t venting properly, you can simply replace the vent valve with a new one. If your gasket is damaged, you’ll need to replace it with a new one as well. In most cases, these parts are readily available at your local auto parts store or online.

2015 Grand Cherokee Gas Cap

If you’re like most people, you probably don’t think much about your gas cap. But if you own a 2015 Jeep Grand Cherokee, you might want to start paying attention. That’s because there have been reports of the gas caps coming loose and falling off, leaving your vehicle vulnerable to fuel leaks.

The problem seems to be with the O-ring that seals the gas cap to the filler neck. If this O-ring is damaged or defective, it can cause the gas cap to come loose. And since the filler neck is located near the engine, a fuel leak could potentially lead to a fire.

So far, there have been no reports of fires or injuries related to this issue. But if you own a 2015 Grand Cherokee, it’s best to be safe and check your gas cap regularly. If it feels loose or looks damaged in any way, replaces it with a new one as soon as possible.

2018 Jeep Compass Gas Filling Problems

If you’re a Jeep Compass owner, you may have experienced problems filling up your tank. It’s a frustrating issue and one that’s been affecting owners since the 2018 model year. The problem seems to be related to the gas cap design.

For some reason, the gas cap doesn’t always seal properly, which can cause fuel to leak out or evaporate. This can lead to a loss of power and decreased fuel economy. Inevitably, this problem will need to be addressed by Jeep.

In the meantime, there are a few things you can do to try and mitigate the issue. Make sure you tighten the gas cap firmly every time you fill up. And if you notice any leaking or Evaporating, bring your Compass in for service as soon as possible so that dealers can take a look at it.

How Does the Capless Gas Tank Work?

The capless gas tank is a new type of fuel system that is becoming increasingly popular in newer model cars. This type of system does away with the need for a traditional gas cap, instead using a sealed, vented chamber that is opened and closed by a lever or button inside the vehicle. One of the main benefits of the capless gas tank is that it helps to prevent fuel evaporation.

In traditional systems, gasoline can easily evaporate through the small opening left by the gas cap, even when it’s tightened correctly. This not only wastes fuel but also contributes to air pollution. The capless system eliminates this problem by sealing off the tank completely when it’s not in use.

Another advantage of the capless system is that it’s more convenient than a traditional setup. There’s no need to fumble around with a gas cap when refueling, which can be especially difficult if you’re wearing gloves or have long nails. Simply open the chamber and insert the pump nozzle into the filler neck.

Fuel economy may also improve slightly with a capless tank since there’s less chance of vapor loss during fill-ups. Studies on this are still ongoing, but early indications are positive. Overall, the capless gas tank is a major improvement over traditional designs and is likely to become standard in new vehicles going forward.

How Do You Put Gas in a Capless Gas Tank Jeep?

If you own a capless gas tank jeep, you may be wondering how to go about filling it up. Here are step-by-step instructions to help make the process as easy as possible.

1. Park your jeep in an area that is well-ventilated and away from any open flames or sources of ignition.
2. Remove the cap from the filler neck on your gas tank. If there is a plastic cover over the opening, remove this as well.
3. Insert the nozzle of the pump into the filler neck and begin pumping gas into the tank.
4. Stop pumping when you reach the “full” line on the pump’s gauge or when the automatic shut-off feature kicks in (if your pump has one). 5. Replace the cap on the filler neck and secure it tightly before driving away.

FAQs

Can I Put a Gas Cap on a Capless Gas Tank?

Jeep Grand Cherokee Capless Gas Tank Problems. Sure, you can put a gas cap on a capless gas tank – but it’s not going to do much good. A capless gas tank is designed to not need a gas cap, so there’s no real opening for the gas cap to seal.

The only reason you might want to do this is if your car came with a capless gas tank but you really prefer the look or feel of a traditional gas cap. But in terms of functionality, it won’t make any difference.

Why Does the Gas Pump Keep Stopping When My Tank is Isn’T Full?

If your gas pump keeps stopping before your tank is full, it may be due to a vapor lock. A vapor lock occurs when the gasoline in the fuel line boils, creating a bubble of vapor that prevents the flow of gasoline. This can happen if the fuel line is exposed to too much heat, such as from the sun or from the engine.

If you think you have a vapor lock, try moving your car to a shady spot and see if the problem persists. You can also try running the engine for a few minutes before filling up to help warm up the fuel line.
