I swear by doing tried and true fuel system configs, and recommend that others do. Regulator as close to the load as possible, properly sized feed & return, and quality parts ( including line, fittings, and proper sumps/vents).
I recently had an issue with fuel delivery, and was surprised when I discovered the cause. My fans have the same gauge wire as the ones coming out of the motors, and used that gauge to wire to a controller, and battery. Total distance, MAYBE 5 feet, probably closer to 3.5 feet.
Running at full blast, for a period of time over 20 min, the wires got hot, and resistance increased, snow-balling until the alt was maxed out, pump (and ECU) starved for power, psi dropped to 36-38 lbs.
Once I picked up speed, and the fans dropped to say 35%, pump picked back up, and car ran stupid rich, until it leaned itself out again. And the cycle started over again once my speed slowed down. Took me a while to figure that one out.
