How to Clean a Fuel System ?

To inspect your fuel system, drive your vehicle to see how it performs. Your vehicle should drive smoothly, accelerate with ease, and go up and down through the speed limits easily. The mileage on your vehicle and the condition of the engine will also have an influence on how the vehicle drives.

If you have a clear fuel filter, inspect the color of the fuel. If the fuel is dark, the fuel system needs to be flushed.

Open the fuel fill cap and try to smell the fuel. If the level is low remove the Fuel Filter (see instructions for fuel filter replacing) and smell the fuel. If the fuel smells like varnish, the fuel is bad.

You may also want to inspect the condition of the fuel lines and fuel tank. If you notice that fuel lines are cracked; (allowing water/condensation to enter the fuel lines) or that the fuel tank is rusted or has cracks, you will want to replace these parts.

For basic cleaning, add a fuel system additive to your fuel tank and top off your fuel level with new gas according to directions on fuel system additive.

Test drive your vehicle to check for improvement. We recommend test driving on normal streets, freeways, accelerating using full throttle, and under regular driving conditions.

If you are still noticing the same symptoms as before the fuel additive, further inspection of your fuel system and drive train is needed.

For next step, the fuel filter needs to be removed, then drain the the old fuel into a metal container by holding the line coming out of the fuel tank in it container, make sure your container is large enough to hold all the fuel, you may keep adding fuel to the fuel tank from the top while the line is in the container, just to wash out all dirt and water out of the system, then install a new fuel filter, and fill out your tank.
For more advanced cleaning you may take your car to a professional mechanic shop, they need to open all the lines and connectors and fittings, and then apply pressured clean air into each line, then clean all the fuel injectors, change the injector O'rings, clean the intake manifold and that is all about fuel system cleaning.
