    OK, I think I may have just gone thru my second Summit electric fuel pump... [​IMG] Do I have to stay electric, or can I go mechanical to avoid this PAIN of replacing my fuel pump every other month?

    Why stay electric on a carb'd motor? The only thing I can think of is security... I run a hidden switch to kill the pump when I'm leaving the truck anywhere questionable. I could just as easily switch the coil + too...

    Thanks all... [​IMG]

    Since you don't have the stock '87FI motor in your beast, I'd go mechanical. Heck, I'd go mechanical if I could on my TPI motor [​IMG]...........

    Then which mechanical pump to buy? I've looked at a few... Edelbrock and BG. Holley probably has one too. Anyone out there running any of these have nothing but good stories to tell? Or bad stories too for that matter [​IMG]!!!

    I had a pretty rowdy 454 in the '75 Blazer I used to have, put an Advance Auto Parts pump in it and never had a problem in the two years I owned it............seems to me a mechanical fuel pump does not need to be a name brand. Unless you're revving that rat way high I'd check the difference in price between a name brand and a stocker and make the decision.

    That's a very good point... but I'm not sure that I can get a refund out of Summit for the pump I bought from them - so I might be stuck taking a Hi-Perf. brand name pump... which is just fine too. [​IMG] If I can refund, I will go that route!

    Just in case though, can anyone give any quick feedback on the three pumps I mentioned previously?

    holley blue pumps work great. The first one I had lasted 3 years in the firebird. The only thing I had to do once in a while is pull the bottom cover off and clean it out since I run the original tank so its got a lot of crap in it :) Its easy to clean the veins out (4 bolts)and the gasket is reusable. DONT USE BG JUNK. everyone I know that uses barry grant has had nothing but problems and try to get rid of it fast.

    Well, I took out the electric and am returning it to Summit for a refund. I went to AutoZone and bought the mechanical pump and pushrod for $20. Installed it in 1hr in the 30* driveway, and she started right up! And as for the BG pumps, I was never into paying out $200+ for a elec. fuel pump.

    For the 454 I bought a pump for a '70 Chevelle w/a 454. It works with no issues.

    Thanks for everyone's replies! [​IMG]
