Fuelab Fuel Pressure Regulator with 0.69" Center Bore

This component can help resolve idle surge, especially with high-flow injectors, and can also address erratic lean air/fuel ratio spikes. The kit features an anodized aluminum housing with a large 0.69" center bore and two in-line inlet/outlet ports.

These ports are machined with 3/4"-16 UNF threads for 8AN ORB fittings, and the kit includes adapter fittings that seal using Viton O-rings. It is safe for use with all fuel types, including alcohol blends like E85, and includes an 1/8" NPT female port for a fuel pressure gauge or other sensors. The damper requires 40-105psi static base pressure and can be mounted at any angle using the supplied M6 hardware.
