Mounting Fuel Regulator
I am need to mount a fuel regulator to the fuel line between mechanical fuel pump and carb. fuel rail. I was thinking mounting it on the driver side interfender. Is there any other places to mount the regulator.
The reason for the fuel regulator is that pressure is over 5 lb.of pressure. |
I have always mounted my regulators just before the carb, AT THE CARBURETOR.
There's no reason to have 3 flexing rubber fuel lines, 1 to the pump inlet, then pump outlet to a solid mounted regulator, then flex line back to the carb. Of course we need to know what carbs you have, what regulator, what engine, and what fuel pump please. Gary |
If you're using Webers, try to mount the regulator at the same level as the carbs. If you mount it lower, you'll lose about 1/3 psi for every vertical foot.

The carb is a 750 vac secondary . The fuel regulator is a Holley pressure 4 to 9 no return line. The fuel pump is a carter just replaced last fall. The pressure bounces around from 5 to 9. So I am installing the regulator. Looked the manifold to mount the regulator couldn't fine a place

FYI: I installed a Carter electric fuel pump in my Cheetah. A few hundred miles later it began to run badly. After a lot of troubleshooting I determined the fuel pump was sending about 10 PSI to the carburetor and overwhelming the float valves. I replaced it with a Delphi unit with the same specs and have had no trouble since then. I paid a little more for the Carter because of their reputation. Perhaps they are not what they once were.

The pressure bounces because of the fuel consumption versus the pump operation, typical of many combos running mechanical pumps, and no pressure reg. Your little Holley dead-head reg will be fine for med horsepower. Can you post some pics of your plumbing between pump and carb? |
