Fuel pump replace
I'm looking at replacing the fuel pump in my car. Here is what I bought:
Will I need anything else? I realize I need to buy a fire extinguisher. I'm going to look into that tonight.
So, I took off the stuff the fsm says to remove. Now it's question time. They say in the manual to depressurize the fuel lines per the procedure. I didn't do real well finding the procedure. Any suggestions?
So here is where I am:
Should I take off the hoses before trying to undo all the bolts? How about that electrical connector, remove it? Should I put anything on the metal lines? Is the pump submersed in gasoline, or is it a pocket with a hose going to the bottom?
Thanks.

Just disconnect the electrical conector and then the three hoses, try twisting them with a pliers before removing. I have better luck with a needle nose and pushing from the end of the hose. Just let the gas run down, or you could wrap the hose with a shop towel. There really isn't that much fire danger unless you are smoking or have the car next to a gas water heater or such. You can relieve the pressure at the schrader on the engine if you wish. It's not near as bad as doing a fuel filter.

Yes, you are supposed to undo the hoses and connector before the bolts. Those old hoses can be a bitch to free. Brush off any loose dirt before hand, so it does not end up falling into the gas tank. You should also have a new gasket, because once the perimeter bolts are out and you lift the unit up and out, the old gasket is likely going to tear. And yes, the fuel pump is submerged in fuel, that's part of how it works.

Ok, I have to order the gasket, or are they stocked at most parts stores? I asked about submersion because it's possible for the pump to be in a void, with the pickup poking down into the tank. Just wanted to know what to expect.

Forget Ecklers. Their $21 price is higher than the GM listed price. And their shipping prices suck.
Autozone don't carry it. If you get it online, but it from rockauto.com
It's $19 at the dealer, and $10.97 from rockauto.com. But after shipping, it's almost the same price and you have to wait for it in the mail just to save a few bucks.
If you have a GM dealer nearby, it's faster and more economical to buy it locally if they have it in stock, since you already have the pump ready to go in. This is a situation where paying a few dollars more from the dealer makes more sense, if they have it in stock. If not, rockauto.com

There are orings on it now and you should replace them. If you don't want to wait for a gasket, one can be made from gasket material for fuel. Pretty easy to do and much cheaper. Would be a good idea to soak those bolts with pb blaster. The heads can snap off. (Ask me how I know!)

Dale, do yourself,and the car, a big favor while you have the sending unit out. See all the rust on the mounting plate? Clean the rust off and apply some coats of a rust killer and paint before you put it back. Saw an 89 vert that had been neglected to the point the plate rusted thru. Every time it rained the tank got more water. When it died the shop pumped 10 gal.of water from the tank. Water had wiped out the entire fuel system and had taken the engine with it. A couple of hours work could pay off very big.

Best and cleanest way to relieve the pressure is to start the car and then remove the fuel pump fuse, and let it die, then turn it over a couple times. Of course if your fuel pump just totally crapped out it won't have any pressure anyways. P.S. this is one of the easiest repairs and the easiest fuel pump you can do.

Fuel pumps have a lot of pressure for the injectors, while running they get hot. So to keep them cool they're in the gasoline.
The gas keeps the pumps cool, a hot fuel pump cooled by gasoline.
Its nuts.
Wow, East coast cars sure get rusty.

Yep, I'm in the "rust belt". Rust happens here. Everyplace has it's pluses and minuses. We get snow and stuff rusts. But, we have fewer tree hugging environazis, less restrictions, and no earthquakes. It's all in what you get used to.
