Well it has been awhile but we have covered some ground, acquired a low mileage roller motor, took to machine shop and it was still usable in factory specs, had vatted, squared, decked, heads decked, crank checked...only thing required was a crank polish (I did learn about metric rings, lol) motor is built and back in car.....only issue is somehow the fuel pump went out between taking it out and re installing it, any ideas? I'm using same eccentric, took pump apart (Holley mechanical 80gph) and all seemed well but will not draw. I am missing something or do I need to just replace it?
wrong It's hemi-orange and only did that because my kid wanted Black with orange trim paint (of course now he's having second thoughts.....how do I prime it?
Disty btw I took that disty to parts store to get a bronze gear and the fellow said he had never seen anyone use a GM disty with Ford bottoms) oh well it's not for long, lol
Primed Ok poured fuel down outlet hose until it was running out inlet side of pump, still no go, however did finally get friend over and we force gravity fed the fuel line into carb, she FIRED! And what a glorious sound, these roller motors are so much more responsive, I can tell it's going to be a beast......guess fuel pump and we will be running right after we fix the water leak that was pouring from the water pump, lol. BUT glad to hear it run, very pleased with the initial fire up and sound, thanks for all input
If it wouldn't prime that way I'd just replace it. Even if you get it working you don't want to be on the side of the road kicking yourself for not replacing it when you had the chance to lol.
Carefully check your fuel line and the hoses that go from the fuel tank to the fuel pump. The metal line could have rusted a hole in it and/or the fuel hoses could have a crack in them. The fuel pump will only pull air if this happens. Since the car has sat for awhile these things can happen!
yes That entered my mind, however I placed a soda bottle fuel of fuel right at the inlet with a hose stuck in it, no way Josa and thats even after priming it, It's gotta be shot, what gets me is I dismantled it and there is nothing to these type pumps, the ballast works fine, the one way valves fine....it just wont draw
Yeah,sounds like a bad pump to me.At least you will get outcheap,I`m getting ready to put an injection pump on my Dodge diesel tow vehicle,$$$$$$$$$$$$$$$$$$$$$$$$.
yep oh yes just FYI I resolved this issue with a Mr. Gasket P95 Electric fuel pump, 7 psi pump requiring no return line or regulator, it supplies plenty fuel...just odd how parts will fail in middle of a project like that, going into tear we know the mechanical pump was working then when we go to fire new motor had me questioning did we put the ecentric back in? does it need a diff ecentric? etc? just plain weird man
