1998 buick regal SC 3.8 fuel pump removal

One is for the fuel delivery, one is for the return and the other one goes to the vapor cannister.

Sounds like a weak fuel pump or clogged fuel filter.Check your fuel pressure it should be 48-55 psi with the key on and engine off.

The fuel pump is in the gas tank. more than likely you have to drop the tank to remove/replace the pump. I would contact you local dealers service dept. as some of those cars had an access panel under the back seat to access the pump without having to remove the tank.

If you have an access panel, it should be an hour or less job with common hand tools.

Open the trunk. Pull the bottom liner free from the trunk by hand, then remove it fully from the vehicle.Remove seven nuts holding down the fuel pump access cover, using a wrench. Lift the cover up and off the cover studs.

Remove the fuel pump retainer with a pair of inside snap-ring pliers. Carefully lift the pump assembly out of the tank. Use caution when handling the pump assembly, as the float and float arm are delicate and can be easily damaged.

Carefully pry the fuel filter off the pump intake nipple, using a flat screwdriver.
Reverse the disassembly steps to reassemble the fuel filter on your Regal.

You didn't mention the engine size, so I included both diagrams...

i believe the washer pump is on the bottom of your reservoir,have to remove the bottle to access the pump

but what the pressure it should be at

check fuel pump fuse and fuel injector fuse.

In my regal gs 1998, the fuel pump is n fuel tank. There is a resister that I replaced to fix stalling and shutting down of engine.
