Re: How do I replace the fuel pump on a 1997 Isuzu Rodeo
To replace a mechanical fuel pump, remove the inlet and outlet lines at the pump.
Use a plug to stop the flow of fuel from the tank.
With the correct size socket wrench, remove mounting bolts. Then, remove the pump from the engine.
Clean the old gasket material from the engine block.
Apply gasket sealer to the mounting surface on the engine and to the threads of the mounting bolts.
Install the new gasket, then position the pump by tilting it either toward or away from the block to correctly place the lever against the cam.
If the pump is driven by a pushrod, the rod must be held up to permit the rocker arm to go under it.
When the pump is properly positioned, there should be an internal squeaking noise with each movement of the pump.
Tighten the mounting bolts firmly.
Attach the inlet and outlet lines, start the engine, and then check for leaks.
