General Discussion / Re: AC Fuel Pump Rebuilds
« on: April 18, 2025, 05:39:07 PM »
I had trouble with this issue MANY years ago. Car would NOT run and smoked. Fuel blowing by needle and seat. On advice from an old mechanic friend, I installed a $15 fuel pump from pep boys and problem solved. I said can I do THIS, or THIS. He said STOP. Don't tell me about anything until you install the cheapy pump and check the pressure. He was correct.
No matter what I asked, the rebuilder could not tell me what the final pressure would be at an idle or running down the road. So I did some experimenting. I wanted to retain the visual of the double AC embossed pump on several cars. I ended up hiding a pressure regulator in the first few inches inside the right frame rail. It has holes in the steel to run the lines. Did that to 4 or 5 different cars. Works great and nobody has ever noticed it after over 100 car shows. In fact, I just saw some light blue staining on one while I had it on the lift. Which is AVGAS. Guess I better take a look at that and see if it can be fixed. Or maybe just replace it. CRAP!!! I just looked at another car on a different lift and it has MORE blue stains on it. Always something with old cars. Danny
