What You'll Learn
Why you should replace your fuel lines
Replacing the fuel lines in your vanagon should be a top priority, especially if you have recently bought the van or don't know how old the lines are. Old fuel lines are one of the main causes of vanagon engine fires, which can cause a total loss of your van.
Vanagons use specific 7mm high-pressure rubber fuel lines and plastic fuel lines around the rear wheel wells. It is important to buy the correct replacement fuel lines, as buying the wrong ones can lead to ballooning and fires. The plastic grommet/nipple piece in the fire wall is known to fail, spraying gas over the engine compartment.
If you neglect to replace your fuel lines, it can burn your van to the ground. It is recommended that you replace your fuel lines every five years or when they become worn.
To replace the fuel lines, you will need to cut one of the short hoses that connect the fuel rail to the injectors. You will then need to cut the same length from your new hose. Removing the hoses from the fuel injectors can be tricky, and you will need to use an X-Acto knife to cut the rubber gasket.

What to do with the old fuel lines
Replacing the fuel lines in a Vanagon is not a difficult task, but it is important to do it correctly to avoid the risk of fire. The old fuel lines should be cut with an X-Acto knife, and one of the short hoses connecting the fuel rail to the injectors should be saved to use as a guide for cutting the new hose.
The old fuel lines can be disposed of in a few different ways. One option is to recycle them, as some recycling centres accept rubber and plastic fuel lines. Another option is to repurpose the old fuel lines for another project, such as using them as tubing for a garden hose or a vacuum cleaner. If the old fuel lines are still in good condition, they could also be donated to a local garage or mechanic shop.
It is important to note that the old fuel lines should not be burned or thrown in the trash, as they may still contain traces of fuel or other hazardous materials. Proper disposal is crucial to prevent fires or other environmental hazards.
When replacing the fuel lines, it is also a good opportunity to inspect the rest of the fuel system for any signs of wear or damage. This includes checking the fuel injectors, fuel pump, and fuel filter. If any of these components are worn or damaged, they should be replaced as well to ensure the safety and proper functioning of the vehicle.
