Return line.
#1 · November 5, 2024, 10:21 am
I have a 30002 EFI 4 600hp system, I bought a Holley in-tank pump 12-374 with a built in regulator at 58psi.
Not sure if I need a return line for my set up, on Holleys product web page it states:
Fuel pressure is internally regulated to 58 psi eliminating the added expense and effort of purchasing and installing an external fuel pressure regulator - no separate return line is required because this module returns excess fuel right inside the tank!

I guess try the pump w/o a return line but be prepared install one if it doesn't work as expected.
