What You'll Learn
Removing the tension ring and o-ring from the new part before inserting it
To remove the tension ring and o-ring from the new part before inserting it, you will need to use a rasp to take the hole out to the first rib on the base. You can then press the new vent valve part into the old base, where it should snap in and be tight. Make sure to remove the tension ring and o-ring from the new part before inserting it.
The tension ring and o-ring are important components of the fuel tank vent valve, as they help to create a tight seal and prevent leaks. By removing the old tension ring and o-ring and replacing them with new ones, you can ensure that the valve functions properly and that there are no leaks.
To remove the tension ring and o-ring, you will need to use a combination of tools and techniques. First, you will need to use a rasp to carefully remove the old tension ring and o-ring from the valve. This process may require some force and precision, as the tension ring and o-ring are often tightly fitted onto the valve. Once the old components have been removed, you can then prepare the new tension ring and o-ring for installation.
It is important to note that the tension ring and o-ring should be replaced with new, high-quality components. Over time, these components can become worn or damaged, which can compromise the seal and lead to leaks. By using new, high-quality components, you can help ensure the long-term reliability and performance of the fuel tank vent valve.

Sealing the new valve
Before inserting the new valve, you will need to remove the tension ring and o-ring from the new part. You can then press the new valve into the old base. To seal the new valve, you can use 4000 PSI epoxy made by Super Glue. Make sure the nipple is pointed in between the two dashes on the tank so it will line up with the hose. After the epoxy has set, cut the nipple off the old vent valve. Then, insert the cut side of the nipple into the hose, leaving enough space for the locking clip on the fitting.

Cutting the nipple off the old vent valve
To cut the nipple off the old vent valve, you must first ensure that the epoxy has set. Once the epoxy is set, cut the nipple off the old vent valve. Then, insert the cut side of the nipple into the hose, leaving enough space for the locking clip on the fitting.
It is important to note that the nipple should be pointed between the two dashes on the tank so that it lines up with the hose. This will ensure that the new vent valve is installed correctly and securely.
Additionally, when removing the old vent valve, it may be necessary to lube the area pretty well to get the old valve out. This can make the process easier and help prevent any damage to the surrounding components.
Finally, when cutting the nipple, it is important to use the appropriate tools and safety gear to avoid any injuries or accidents. This may include wearing protective gloves and eye gear to shield your eyes from any debris.

Inserting the cut side of the nipple into the hose
To insert the cut side of the nipple into the hose, you must first ensure that the nipple is pointed between the two dashes on the tank so that it will line up with the hose. Once the epoxy has set, cut the nipple off the old vent valve and insert the cut side into the hose, leaving enough space for the locking clip on the fitting.
The nipple should be cut off the old vent valve once the epoxy has set. This is to ensure that the new valve is stronger than the original equipment manufacturer (OEM) fitting and seals back up nicely.
The nipple must be inserted into the hose, leaving enough space for the locking clip on the fitting. This is an important step to ensure that the new valve is secure and functional.
By following these steps, you can successfully insert the cut side of the nipple into the hose when replacing a fuel tank vent valve.

Removing the seal
First, it's important to understand the seal's function. The seal, also known as a grommet, is a rubber component that the valve fits into. It creates a tight connection between the valve and the fuel tank, preventing fuel vapour leaks. To remove the old seal, you'll need to apply some lubricant to ease the process. Work the lubricant into the rubber grommet, ensuring it's well-coated. This will help the old seal come out more smoothly.
Next, you'll need to access the seal. As suggested by a Jeep enthusiast forum, removing the fuel tank module can make this process easier. With the module removed, you can reach the seal more easily. Now, it's time to remove the old seal. Using a combination of pushing from the inside and pulling from the outside, apply gentle force to remove the seal. Be careful not to damage the surrounding components or the fuel tank itself.
If you're replacing the seal, it's important to choose a suitable replacement. A Crown seal is a popular option and may be available at your local parts store. Alternatively, you can order one online, but be mindful of shipping costs, as they may exceed the price of the seal itself. Once you have the new seal, inspect it to ensure it's in good condition and free of any defects.
Finally, installing the new seal requires careful alignment. Ensure the new seal is properly lubricated before inserting it into the valve housing. Position the seal so that it's wider at the top, matching the shape of the old seal. Gently push the seal into place, ensuring it's securely seated. With the new seal installed, you can proceed with the rest of the fuel tank vent valve replacement process, confident that your fuel system is properly sealed.
