dl456 Posted July 31, 2017 Share Posted July 31, 2017 Hello, I will be on my third new fuel pump in the last few years and my car is not officially on the road yet. The last one was a new Airtex I believe. The car has been sitting in the shop during assembly. The push rod is new and appears to have good travel. When I remove the pumps and work it by hand, I have little to no vacuum or pressure. Anybody have a similar experience with replacement pumps? Any suggestions on finding a good one? Thanks, Dennis Link to comment Share on other sites More sharing options...
peecher Posted July 31, 2017 Share Posted July 31, 2017 Yes , even though "they" tell you the pumps are rebuilt/made with soft parts that are "fuel" proof; they aren't. Some seem to lose their "seal" at the diaphragm after about a year? I've had the best luck with pumps from Earle Brown Jr.; see "sources". Link to comment Share on other sites More sharing options...
dl456 Posted July 31, 2017 Author Share Posted July 31, 2017 Thanks Peecher, I suspected that. One pump that I disassembled clearly had some leakage at the diaphragm but no apparent cause. The second one that I had apart had some issues with the valve function but no apparent corrosion or decay. I just don't get it. Will try Mr. Brown. I for one, miss your once frequent posts on these forums. Hope all is well. Dennis Link to comment Share on other sites More sharing options...
Tom_Overfield Posted August 2, 2017 Share Posted August 2, 2017 I rebuilt my carb twice, once over 30 mph, it couldn't supply enough gas. I had installed an electric fuel pump earlier and when I drive the car now, I reach under the dash, flip the switch, end of problem. Either a worn cam lobe or worn pushrod on mine.

DSpringer Posted September 20, 2017 Share Posted September 20, 2017 My original pump could not supply enough fuel. I ran it for awhile with a spacer to get more lift, but that was an imperfect solution. I bought a new one from Sacramento Vintage Ford, and couldn't keep it from overpowering the float valve and flooding the engine with gas. I replaced the spring with the spring from the old one, and now it is "just right." I have over 2,000 miles on it and no problems. Link to comment Share on other sites More sharing options...
