Fuel pump pressure

JasonNC

I have installed a Carter rotary electric fuel pump, a Holley 12-804 fuel pressure regulator, and a Holley 26-500 pressure gauge on my 49 Super Six coupe. It has a 262 engine with a Twin-H setup. According ChatGPT (my daughter turned me onto it), I should shoot for pressure in the 4 to 4.5 psi range. Thought I would get an opinion from a human source.

The manual lists 3 to 4 psi for the combination pump and 3 1/2 to 4 1/2 psi for the standard pump. I run 3 1/2 on my 262 twin H and don't have any issues with carb needles leaking.
