V8 Fuel Pump Options

[scoti]

78 Malibu w/a <50k stock 2bbl/sbc. The fuel pump was/is leaking from around the crimped seam that held the top & bottom together.

The previous owner had purchased an 'AC Delco' pump & it was swapped on before I started working on the car (prior to Feb '19). While diagnosing possible issues after the car died (Jun '19), I replaced the 'new/leaky/Delco' pump when replacing all the rotted fuel lines. The 'new' pump I installed is a Delphi unit & was installed @ the beginning of July. It is the same constuction as the AC Delco was. After noticing a strong gas odor when parked in its garage, I found it's also now leaking @ that same crimped seam.

Is there a standard replacement parts manufacturer that makes one thats bolted together vs the crimped version? This doesn't need anything high end but I'd like to eliminate the leak.

Carter, holley, edelbrock have 80 gph fuel pumps in bolt together. They won’t be as cheap as a stock one.

I had one of the Holley/Mr. Gaskets break the neck at the block on my Olds; won't do that again. I've never seen one fail at the crimp like that. I've always had good luck with Carter mechanicals.

I had a moroso pump that was worked well and no leaks

My stock one failed at the crimp, but after 100,000 miles. Was a really bad oil leak all over but like you said, I had never seen one fail there either.

I'll try a Carter next. That was the only other OE supplier type I could think of.

How many lines/inlets/outlets on the pump 2 or 3

Just two. Supply to the pump & discharge to the carb.

u have a factory V8 u should have 3

where is the return line

 

[Bonnewagon]

Not all had the third return line. AC equipped surely did to eliminate vapor lock. I just installed an NOS 30+ year old Airtex fuel pump and it is in perfect working order.
