Cleaning automotive fuel lines involves cleaning out build-ups and slimy deposits that clog the fuel lines and cause lower engine performance, difficulty in starting the car, smoke in the car, unclean emissions and engine switching off. You can clean the fuel lines inside the car, or you can remove the lines and clean them from outside.Continue Reading
The first step is to locate the fuel lines in the engine compartment under the hood of the car. Ensure the engine is off. Connect the fuel inlet to the outlet or to another tube, or detach the fuel pump to prevent fuel return. This ensures that the fuel does not enter the engine when you start the car.
Next, connect a pressurized cleaning fluid to the fuel lines, and then start the engine. While the engine is still running, stream the pressurized solvent through the lines. When this is done, turn off the engine, and reconnect the fuel lines and any other disconnected parts. Confirm that the problems caused by the clogged fuel lines, such as dismal engine performance, have been fixed. Professional cleaning may be required if this process does not solve the problem.
It is important to wear eye and skin protection when working with cleaning solvents and pressurized systems. Solvents are also flammable and should be kept away from open flames.Learn more about Car Parts & Maintenance
