Product Details

The Holley Billet Bypass Fuel Pressure Regulator Kit provides precise fuel pressure control for return-style fuel systems. This complete kit includes everything needed for professional fuel pressure management, including a billet aluminum regulator body, mounting bracket, fuel pressure gauge, and adapter fittings.

Key Features:

  • Adjustable fuel pressure range from 4.5 to 9 PSI for carbureted applications
  • Billet aluminum construction for durability and heat dissipation
  • 3/8" NPT inlet and outlet ports for standard fuel line connections
  • Includes Earl's fuel pressure gauge (100187ERL) with 1/8" NPT gauge port
  • Complete mounting bracket included for secure installation
  • Bypass design requires return line back to fuel tank
  • Adapter fittings included for gauge installation

Designed for use in return-style fuel systems, this regulator maintains consistent fuel pressure by bypassing excess fuel back to the tank. The included gauge allows for real-time monitoring and precise adjustments to ensure optimal engine performance. Ideal for street rods, muscle cars, and carbureted performance applications requiring low-pressure fuel delivery.

Super quick and easy

Quick easy processing and buying format.

So far so good waiting for delivery date

Great

Overall experience was very good. There was a delay in the shipping but that was due to the shipping agent. It does seem that the website is not optimized for tracking shipment using smart phones. Tracking worked fine on a PC, not mobile functionality seems to be difficult. Price was good and making use of Affirm provides additional ways of payment which is very helpful.

Didn't receive what I thought I was getting, but still a good purchase
