1972 Cutlass Supreme with a 350. No output from the fuel pump. Any recommendations on a brand for replacement? Never replaced one before. Any tips on procedures and can it be done from the top?

 

For a stock 350 any decent brand-name pump should be fine.

It's not hard to change: Remove lines, remove nut and bolt, remove pump, replace with a new one.
Personally, I'd be inclined to put a smear of grease on the arm, and to turn the motor until the cam is on the low side, to make it easier to install, but it should work fine even if you don't.

No my pic but here is what it looks like installed.

 

Thanks! Hopefully it won't be too bad then but will need to work around the AC bracket.

 

Are you sure it's the pump? Does the oil smell of gasoline (which would indicate a rupture of the pump diaphragm)? If it does, it's the pump. If not, I'd check the rubber hoses from the tank to the hard line and from the hard line to the pump before spending a dime. These hoses crack, causing the pump to suck air.

 

I inspected the rubber fuel line and Joe was right. The small section of rubber hose near the tank had a crack. Since I had it apart, I decide to replace all the rubber hose and fuel pump anyway.

 

Keep the old fuel pump in the trunk.

Glad you got it fixed!

I just replaced mine in my 72 Cutlass S a few months ago, you were right about the fact it's a tad tricky working it around that A/C bracket, but otherwise it was a fairly easy operation. I'm suspicious the ethanol did it in, it was SHOT. I got mine from Rock Auto, if that ever helps anyone in the future. No issues with the replacement thus far.

 

Since mine might still have some life in it, it's not a bad idea to keep it around for a spare. I bought an Airtex off of Amazon for about $25.
