Hey guys, I think I need a fuel pump. But before I buy one I want to see if you agree. Got a 302 with an Edelbrock carb, a (presumably) stock or stock replacement mechanical fuel pump, and what I'm told is a "reconditioned" fuel tank. The car runs great except for one thing. When I make a hard turn, say from a stop light, then nail it, it falls down after a couple of seconds. Bogs like it's not getting fuel or spark. I let off, hit it again and it's fine. Nail it from a stop without a turn and it's fine. Reason I say it's fuel is because it's only happening when I really put my foot in it after a hard turn. My theory is this: Fuel in the tank sloshes to one side, the pump sucks air, and there's not enough fuel in the bowls to to compensate for it. To me that sounds like two problems: One, the tank's possibly not baffled, and the big one - not enough fuel pressure to keep the bowls full. Am I right? My proposed solution is to get an electrical pump that pushes 4-6 constant PSI. I figure I'll wire it with a vacuum switch for safety. That has some advantages, although I'm not excited about putting yet more electrical load on my stock type alternator. Can I even get away with a mechanical pump with my setup? Is my mechanical pump going bad, or is it just not enough?
Me four. But if you do need a new pump, a mechanical one should work fine since that's what they all came with.
Somehow, I get the impression you guys think I need to adjust my floats. :16suspect That didn't occur to me since I rebuilt the carb recently and adjusted it to spec, but that idea's cheaper than a fuel pump, so I'll give it a shot. Thanks!
Well, the floats are set normal... What's the next idea? When a Ford mechanical fuel pump fails, does the pressure fall off? I mean does it "start to go bad" or does it just stop working?
