Holley EFI has all the goods for all your street and track enthusiasts. Holley's new universal bypass fuel pressure regulators are built to handle fuel systems in any application, whether you're tearing up the streets or dominating the track.

Designed for systems with a return line back to the tank, these regulators give you adjustable base pressure with ranges from 15 up to a whopping 90 psi. You have the power to fine-tune that fuel pressure exactly to your combination. They come with a 1/8-inch NPT boost reference port, set at a ratio of 1:1. That means you've got that extra boost control right at your fingertips. We've also included a 1/8-inch NPT fuel gauge port to keep an eye on fuel pressure.
