Aeromotive X1 Series EFI Bypass Fuel Pressure Regulator - 35-75 PSI - 0.313" Valve - (2) -08 ORB Inlets

The Aeromotive 13305 X1 Series EFI Bypass Fuel Pressure Regulator provides precise fuel pressure control in a modular, high-flow design. As part of the X1 platform, this unit is 33% lighter and more compact than the classic 13109 regulator while stepping up to larger -08 ORB ports to support increased volume. Its internal geometry is optimized to eliminate the performance compromises found in traditional convertible regulators, ensuring consistent pressure regardless of your induction setup.

Built for versatility and high-output builds, the 13305 handles up to 250 GPH and is fully compatible with gasoline, ethanol, and methanol fuels. It features a 1:1 boost reference ratio for forced induction applications and includes a 1/8" NPT gauge port for easy monitoring. The 0.313" bypass valve and matching spring are specifically tuned for EFI pressure ranges between 35 and 75 PSI.
