BB fuel pump replacement

Gees, I'm not looking forward to this. 70 LS5 with %{#* a/c

Whats the easiest way to do this? Pull the body, pull the engine, sell?

I know how you're supposed to go about it, I'm looking for sympathy or someone with fingers like ET.

It’s a shitty job for sure, especially with factory AC. A lift is your friend. Good luck. Make sure to put a good quality AC Delco pump on there if you can.

I like pulling the wheel. It helps.

Piece of cake doing it this way,also make sure you're on #1 firing order as that's when the rod will go up the farthest and use a little grease to hold it up.

GOOD TIP! I never thought about this. I just always fought it for hours trying to get the bolts started against the compressed pump..

Thanks for the tips guys.

Getting the rear (left) bolt out/in is tough, had to use a long extension and go in between the frame and the inner fender to get to it. I'd like to replace the rubber section of hose that goes between the pump and the steel fuel line but I can't get to it.

FYI There is a "S" shaped hose available. Don't just use a piece of straight fuel line as it will kink.

Replaced my pump a few weeks ago in my 70 ls5 with air. Not too bad getting it off. Getting it sucked with getting the bolts in, but got it done. Passenger wheel off, long extensions to go between inner fender and frame.
