Fuel Lines & Hoses

Aftermarket & OEM Fuel Lines & Hoses

If you drive a car, truck, or anything on the road with an engine, chances are good the vehicle you're driving has a fuel system. The chances are also pretty darn good that the fuel system uses lines or hoses to transport the fuel from the reservoir, or tank, to the engine cylinders for combustion. These are an integral part of the fuel system for you vehicle. Eventually, the rubber components will need replacing because they age and become brittle, and this is the most common reason for failure of these parts. Typically, the inside of tubes are made to handle the deteriorating effects of fuel, however the outside of the rubber tubes are exposed to the elements and the constant hot, cold, hot, cold can cause the rubber to dry up and crack, causing a leak. A leaking fuel line is an extremely dangerous hazard that can result in fire damage to both you and your vehicle. If it's leaking, you may notice a puddle of fuel under the vehicle, or you may smell gas when you're inside the car. If you notice either of these symptoms, get it repaired right away. If you purchase a length of hose with the correct inside and outside diameter, it's a relatively simple job to do yourself.

Most modern fuel systems have multiple lengths of different materials for their lines and hoses. Usually, there's a metal line that runs the length of the underside of the vehicle, and there's rubber connecting hoses on either end. It's at these rubber connectors where the high majority of problems can occur. The metal portion in the center normally doesn't need to be replaced unless it's been damaged. Fuel lines in modern electronic injection vehicles are high pressure lines so caution is advised when replacing them.

Replacing the rubber portion of the fuel lines is a pretty straight-forward job so long as you have the proper tools, the correct replacement hoses, and a repair manual. Below, we've provided a few very basic steps to replace them.

  • Remove the fuel pump fuse and run the engine until it stops. This removes the fuel from the lines without pumping more fuel from the tank.
  • Un-clamp the hose and remove it. Have shop rags and maybe a container ready for excess fuel.
  • Remove any dirt or residue from the metal line ends.
  • If you need to, use the old hose length to determine how long to cut the new hose.
  • Place the clamps loosely over the new hose and slide each end over the metal tubes.
  • If there is any kinks in the tube, remove it and trim some off an end to remove the kink.
  • Tighten the clamps at both ends. Replace the fuel pump fuse.
  • Dispose of any fuel-soaked rags or parts properly.

A cracked and leaking fuel hose is a very dangerous situation that needs prompt attention. It can result in a fire causing damage to the car, to you, and most insurance companies catalog fire damage as a total loss.
