Doug&Deb Posted April 24, 2023 Author Report Share Posted April 24, 2023 I’m definitely leaning towards the pump being the culprit but I need to drop the tank also. I have a leak somewhere on top but not from the sending unit. I’m planning on swapping engines soon and I don’t want this to continue to be a problem. The rebuild has a good mechanical pump so I want to check the tank and fix or replace if necessary. I appreciate all of the help. This forum keeps me half ways sane lol. In the meantime I’m going to drive it and hopefully the electric pump keeps it going. Quote Link to comment Share on other sites More sharing options...

If you stand infront of the car and look at the engine, The engine turns clockwise, Every other engine I have worked on turned ANTI-clockwise. When I was setting the timing I was accidentally retarding the timing thinking I was advancing it. What have you been working on!? With the exception of some dual engine boats i've never encountered a CCrotation. Quote Link to comment Share on other sites More sharing options...

DJK Posted April 25, 2023 Report Share Posted April 25, 2023 10 hours ago, Doug&Deb said: DJK what you’re describing sounds like fuel percolation. That happens when you shut the car off for a short time and it’s hard to restart or it stalls after being restarted. To answer the other questions: my cap is vented and I don’t think the electric pump is causing any restriction. I’ve had it on the car for about 2 years now and this problem just started. Vapor lock or percolation to me result in the same thing, but either one usually occurs sitting with engine off, I may stand to be corrected. I was thinking a restriction in your manual pump which would cause the e pump ineffective???? I completely eliminated the manual pump and use a Carter P4259. 1 Quote Link to comment Share on other sites More sharing options...

The toilets rotate backwards, why no the engines, lol. 1 Quote Link to comment Share on other sites More sharing options...

I suffered vapor lock on a very hot day here. It was over 100F. I was part of a large group of vintage cars. In excess of 150 cars I estimate. It was slow going in the downtown core. Block to block, light to light. My engine was getting hot and it started bucking and kicking. I left the parade of cars, and got my ground speed up on more-open roads. Shortly after I got my speed up, the wind cooled things down. No more engine bucking. It was indeed vapor lock. On my other car I experienced similar. I installed a back up 6V electric fuel pump, in line. When vapor lock starts to appear, I hit the electric pump toggle switch and the symptoms immediately disappear. Whether parked or when actually driving it has happened to me. The electric backup pump solves it. I still run mechanical fuel pumps full time on both of my old Mopars. I have rebuilt them both myself. It's not hard to do. Since those episodes I also only run non-ethanol infused fuel. It helps too.

maok Posted April 25, 2023 Report Share Posted April 25, 2023 Three changes I make to my cars; 1. Electric fuel pump (full time) and a regulator. 2. 12volt and alternator 3. Electronic ignition - Pertronix. If your fuel filter is clean then I would not bother with cleaning the fuel tank, though it wouldn't hurt. I am about to cut open and clean the tank on a '74 DS23 Citroen, it's been causing me all sorts of trouble. Quote Link to comment Share on other sites More sharing options...

Haven't seen under the hood of a Subi in years, but all mopars(flatheads, /6, all V-8s) are cw rotation. Again, except for some dual boat installs. 1 Quote Link to comment Share on other sites More sharing options...
