Hi folks end hope everybody’s having a decent Saturday.
I need to button up another project car that was previously (long time ago and original engine long gone) a fuel injection car so it’s got the return line like they all do. It looks like many of you like to use a pressure regulator in the return line, rather than simply capping it off, and I was wondering if there’s a specific regulator that you would recommend or if a Holley rotary dial to select pressure unit is fine to use. Thanks! |

Thanks! How are you running the return? With a "T" fitting, or flowing into one carb and out the other carb then returning to fuel tank? With the right fuel pump you wont need to regulate. Matt |
