How to Replace the Fuel Pump on a 2000 Saturn
The fuel pump to your Saturn is what pressurizes the gasoline in the fuel tank and sends it to the fuel injectors and then to the engine to burn. If you are experiencing problems while driving your Saturn, such as sudden bursts of acceleration when pressing on the gas pedal steady or if the fuel pump is making noise and/or leaking, then the pump may be faulty and need replacing. This is a task that requires additional and more advanced knowledge about automotive repair, specifically in fuel and exhaust systems.
Instructions
Removing the Fuel Pump/Level Sensor Module
- 1
Relieve your Saturns fuel pressure system. Remove the fuel cap to equalize the pressure in the fuel tank.
2Remove the negative cable from the battery.
3Raise your Saturn with the jack and support it with jack stands.
4Remove the fuel tank from under your Saturn. The tank must be as empty as possible, which may require some siphoning (with a siphoning kit).
5Pinch together the legs of the retainers on the supply and return fuel lines with your needle-nose pliers. Pull the fittings from the fuel pump/level sensor module. Use a shop rag for any spilled fuel.
6Mark on the fuel pump and on the fuel tank its exact position in the tank. Make sure these indicators align.
7Unscrew the modules locknut counter-clockwise with your large channel locks. You may need to loosen the locknut using a hammer and a brass (not steel) punch.
8Take out the module through the mounting hole. Be caul not to abruptly pull on the module, potentially breaking off the float or float arm into the fuel tank.
9Check the O-ring seal on the mounting flange and replace if damaged.
Installing the New Fuel Pump/Level Sensor Module
- 10
Mark the new module on the same areas you marked on the old module to erence its position in the fuel tank.
11Install the new fuel pump/level sensor module into the mounting hole of the fuel tank with care. Do not harm the fuel inlet strainer, float arm and float while inserting the module. Line up the markings you made on the module and fuel tank.
12Install and screw on the modules locknut. Tighten it down with your channel locks.
13Connect the fuel supply and return lines to the module. Check that they are secure on the module by lightly twisting and tugging them.
14Install the fuel tank back under your Saturn.
15Pour the fuel from the gas can into the filler hole. Install and tighten the fuel cap.
16Reconnect the negative cable on the battery.
17Remove the jack stands and lower your Saturn.
