Supplemental electric fuel pump and regulator rec's

This is what I’m running with 540hp, 3/8” feed and return lines, QF 850 and a regulator. No issues with heat or maintaining stable fuel pressure, even in CA heat. The only time you’ll hear it is before you start the engine.

Jimmy, thanks for the link I was just about to search for where I got my current one and you posted it! Been about 6 years since I installed mine and wanted to pick up a spare.
