Hi everyone , i been working on my 1967 for a year so far...
Im doing a full restomod not to crazy but with a few good mods .
I have a holly red fuel pump with a regulator , once i mount the return line to the tank where on the front i conect the return line , to the regulator (wich brand and kind ,model etc) im a lil lost and everytime i start the car and its in idle i can hear the pump dragin because its building too much pressure , folow...... because no return line . . . ..
If anyone out there have a solution let me know . . . . . .
Holley red fuel pumps only put out 5-7 psi. You dont need a regulator with it. Most carb needles will hold 7 psi without being unseated by the pressure. Your Holley pump has and internal regulator piston and spring that diverts fuel back to the inlet side of the pump when 7 psi is reached. You do not need a regulator or return line. And they are usually noisy and will sound like they are bogging down when max pressure is reached.
My wife calls me a transplanted redneck. All I got to say is. Hey Yall watch this!!!
Pacus90, that can't be your car in your Avatar pic, there are no hills that steep in Florida to get that kind of air!!!
I don't know why, but it seems hard to make a quiet fuel pressure regulator. My Dad has a 1950 Shoebox, and the regulator is louder than the McCullough supercharger! It is not in a good place though, right on the firewall. He intends to move it, but something always gets done first.
