Replacing the fuel line on your vehicle can take anywhere from two to six hours. Depending on your car’s make and model, it may be a complicated procedure that involves removing many components. You should have your fuel line inspected or replaced once every 50,000 to 75,000 miles or according to the recommended schedule in your owner’s manual. It’s essential to get this service regularly because a faulty fuel line can undermine the operability, performance, and safety of your vehicle. If you have a leaky fuel line, it can potentially start a fire.

While you can save money by replacing your fuel line yourself, bear in mind that fuel lines come in different types, materials, and sizes. Make sure you choose the correct fuel line for your vehicle. If you’re unsure, refer to your owner’s manual. In some cases, the fuel line may be difficult to locate or can only be replaced after removing the fuel tank or other components. If you don’t have the necessary skills to perform the repair, it’s best to leave it to a professional.

What Is a Fuel Line?

A fuel line is a hose or pipe that carries fuel from the fuel tank to the engine of a vehicle. It’s connected to the fuel pump, which draws gasoline or diesel from the tank to the fuel injectors or carburetor. A fuel line is designed and installed in such a way that it can withstand the severe vibration that comes from the engine and road surface. Additionally, it’s placed away from exhaust pipes and mufflers so that excessive heat won’t cause vapor lock.

What Does a Fuel Line Replacement Include?

Typically, the process of replacing a fuel line begins with draining the fuel out of the line. You will need to use jack stands and a hydraulic jack to raise your vehicle high enough so that you can work under it. After that, loosen the fuel line connections to allow any residual fuel to drain out. To remove your old fuel line, disconnect the fittings on both ends of the fuel line and loosen all the mounting clamps that hold the line in place.

While changing your fuel line, you should also check each fitting for stretched or damaged threads. Replace the fittings if they aren’t in good shape. Furthermore, you’ll need a new ferrule on each end of the new line. Allow about 1/16 inch of the new line to stick out from the ferrule to ensure a good seal. When installing the new fuel line, make sure it conforms to the locations of the end fittings and mounting clamps. Then tighten the fittings and clamps.

If you prefer to have your fuel line replaced at an auto repair shop, the process will be pretty much the same. This procedure usually takes two to six hours, but a professional mechanic can do it more quickly thanks to having a lift and specialized tools for this purpose.

What Happens If You Don’t Replace a Fuel Line?

Your fuel line plays a vital role in the operation of your engine, as it delivers the fuel it needs to run. An old fuel line has a greater tendency to get clogged, which may lead to starting problems. Fuel lines may also develop leaks as they become worn or damaged due to rubbing against the metal surfaces around them. Particularly in northern climates, metal fuel lines are prone to rust, which can also cause leaks. A leaky fuel line can cause fuel pressure to drop, potentially resulting in engine misfires, stalling, or hard starting. It also poses a safety risk to you, your passengers, and nearby motorists. As a highly flammable substance, leaking fuel is one of the leading causes of vehicle fires.

How Often to Replace Fuel Lines

Generally, experts recommend replacing fuel lines every 50,000 to 75,000 miles. However, the ideal interval may vary depending on a number of factors, including the make and model of the vehicle, type of fuel line, and driving environment. To be safe, you should check your owner’s manual or use the free FIXD app to find out the suggested interval for your specific vehicle model.
