Default fuel pump change

I had wanted to do quite a few things performance wise by this time but havenít gotten around to it. So now Iím aiming for spring and in the mean time I want to take care of a few things for peace of mind (coupler is a easy one) and before they become a issue down the line. One thing being a fuel pump with a rewire kit. Any body got a walk through they can give me and any tips and tricks that would aid me? Thanks everyone

Only thing I can suggest is get the tank strap in advance.. some are PITA to get out and may not be saveable once you drop the tank to get the fuel pump.. if you're able to re-use it.. ensure the place you buy it from will take the new ones back.

Ed, is your fuel pressure low? Have you diagnosed it so that you know it'* not an FPR? Check your straps in advance. They may not be in bad shape. Pre-lube the two bolts a day ahead of time with PB Blaster.

That'* good advice, because when you break them off you have a whole new problem that definitely happend to me.

I would also suggest that if your car is still fine and you are replacing the fuel pump, run the car very low on gas before you do it so the tank isn't as heavy

Have new fuel line clips available. Mine had fused themselves to the corroded sender tubes to the point I had to remove them piece by piece with needle nose pliers.
NAPA had a few different pumps, and the cheapest was not direct fit, but the second cheapest was an exact fit. Looked exactly the same as the old one....And was only $11 more than the cheapest.
My straps were fine. The only corrosion on the entire car was on the metal fuel lines...

The gasket included with the new pump that seals the fuel pump assembly into the tank is usually just a rubber o-ring.

These suck. Buy the gasket with fingers that drops down into the hole from the dealer. It seals better and saves tons of time.

Thanks for the advice everyone, my fuel pressure is not low nor is it doing anything to make me suspect my fuel pump is on it'* way out. I just want to replace it and not have to worry about it for miles and mods to come.
(right now I'm just planing this out )
