jord Posted November 20, 2023 Share Posted November 20, 2023 Thinking of installing a fuel regulator, the higher pressure changed my float setting previously. Can I install one under the car next to the electric pump yet before the mechanical pump? Used only for priming. Also is the Holley brand any good, seems to have a few negative reviews?

19tom40 Posted November 27, 2023 Share Posted November 27, 2023 A fuel pressure regulator has to be on the output of the fuel pump. It should work if placed under the car. I would measure the pressure at the output of the mechanical pump. I cannot recommend any fuel pressure regulator as I am still running stock mechanical pumps on my cars. I would look for an electric pump that delivers a max pressure of 3lb. The Airtex E8902 is one for a 6 volt car. Link to comment Share on other sites More sharing options...
jord Posted November 28, 2023 Author Share Posted November 28, 2023 Thanks' Tom, they are currently unavailable so will have to wait and see if they make them again, my existing one is 5.5 lbs a little too strong for the carburetor. I will just have to learn to ease up on the primming. Messed up my float setting. Link to comment Share on other sites More sharing options...
19tom40 Posted December 6, 2023 Share Posted December 6, 2023 My cars both start with little cranking after sitting a couple of months. After sitting all winter, my Merc start after cranking 3 - 10 second bursts and my Lincoln takes about 8 bursts. My Lincoln carburetor leaks down so it takes longer to start. The key to starting after long periods of inaction is a one piece fuel line from the tank to the flex line, crimp the ferrules and then solder them at both ends, use a good flex line and a good sediment bowl cover gasket. Any vacuum leaks will slow the priming action. Link to comment Share on other sites More sharing options...
