The fuel line of your car supplies gas from the fuel tank to the carburetor, making the combustion necessary for the engine to run. If you smell a strong whiff of gas from your car when it is running, you may have a gas leak from the fuel line. It is essential to repair this immediately to prevent an explosion. If you are not certain of your repair abilities, it is best to take your car to a certified mechanic.

Step 1

Locate the fuel supply line in your engine. The fuel supply line is near the fuel filter at the back of the car, near the gas tank.

Step 2

Place a towel underneath the fuel lines to prevent gas leaks from forming.

Step 3

Use a wrench to unscrew the holding nuts, thereby removing the low-pressure fuel line to gain access to the high-pressure fuel line.

Step 4

Slowly turn the fitting for the high-pressure fuel line to relieve the fuel pressure from the fuel line. This prevents fuel from spraying.

Step 5

Remove the high-pressure fuel line and check for leaks. Replace the pipe if it is leaking.

Step 6

Squeeze the epoxy from the tube, applying a thin layer around the entire leak area, if it is coming from a connection point. Allow the epoxy to dry thoroughly, then tighten the bolts in place. Use a fuel resistant epoxy, found at most auto supply stores.
