The fuel lines transfer fuel from the fuel tank to the throttle body or the fuel rails. Fuel lines are made of plastic, nylon, rubber, or metal. They are also called hoses, tubing, or pipes. A hose is flexible. Tubing may be flexible or rigid. Pipe is usually rigid. Understanding what type of hose you are replacing is critical to a successful instalation.
Determine type of fuel line to be replaced. Rubber hoses will have clamps on both ends that should be loosened with screw driver. Nylon and steel lines will have a ferrule at both ends removed and replaced using proper size line wrench
Using proper size line wrench or screwdriver, loosen fittings by turning counter clockwise. Catch fuel remaining in lines in a gasoline safe container.
Remove defective fuel line and install the new line or hose opposite of removing. Take care not to strip or cross-thread fittings as this will cause leaks.
Dispose of remaining fuel in an OSHA safe container.
