Fuel Pump Replacement

[ctaco]

I have a 1996 Buick Regal Gran Sport. There is no access hatch for the fuel pump. I have noticed an electrical whine coming from the pump and want to plan on a replacement at some point. I think that dropping the fuel tank seems like a major pain especially while only using jack stands. Has anyone else found a good solution to replacing the fuel pump? I'm okay with cutting out a portion of the trunk and patching it when I am done. Is there a good way to do this without sparks so I don't have sparks near gasoline? Are Delphi fuel pumps a decent replacement?

I just dropped the tank on my Lumina a few days ago. Don’t cut a hole in the floor, it’s really not that hard, just kind of sucks to reattach the vapor lines. 
 

 In a nutshell…

 -there’s an exhaust heat shield that had to come off. 

-unplug 2 fuel lines, 3 vapor lines, the electrical connection, and two fuel fill pipes at the tank. 
-15mm bolts on the straps, and it comes down.

It took me all of 10 mins to drop the tank. I’ve replaced the tank and fuel sending unit twice (from rust damage from sitting) and a third to reseal the sending/pump unit.

 Delphi pumps are good, but buy a GM fuel sending unit gasket. Don’t use aftermarket.

How loud is this whine, one is supposed to hear the pump running........when one turns the ign key to *run* you will hear the pump spin up for a moment then it stops. When the engine is running if you get under the rear of the car you will hear the pump running.

It depends on the day, but it is pretty noticeable. It doesn't get louder if I am driving or if I am sitting still. It is however loud it is until I turn the car off and then the next time I start it, it might be loud or it might quiet down some. I don't have my rear seats installed which contributes to some additional noise, but pretty sure it has gotten louder in the past couple months.

Thanks for the info. That is a nice looking tank. Where did you order that from?
