Spool Performance FPR-T Compact Billet Fuel Pressure Regulator

Spool Performance FPR-T Compact Fuel Pressure Regulator

Precise, stable fuel pressure is the foundation of a well-built fuel system. The Spool Performance Compact FPR was developed to deliver exactly that — reliably, over the long term.

Built Differently

The budget regulators flooding the market share a familiar set of failure points: rubber diaphragms that deteriorate under sustained use, internal components that struggle to seal correctly, and materials that wear far sooner than they should. We built ours differently. The body is CNC-machined from 6061 billet aluminum, and the internal wear surfaces are all hardened stainless steel — materials selected for their ability to hold tolerances, resist corrosion, and perform consistently whether you're running pump gas, an ethanol blend, or straight E85. It also features a fiber reinforced seal diaphragm that guarantees a higher reliability and operational stability.

Fitment

The M18 ORB inlet ships with a 6AN fitting included as standard. For builds requiring larger fuel lines, it accepts M18 ORB-to-AN adapters up to 10AN, keeping the regulator compatible across a wide range of fuel system configurations.

Compact by Design

Size was a priority from the start of development, not something addressed at the end — but so was aesthetics. The goal was a regulator that fits where others don't while actually looking like it belongs in a well-built engine bay, not something you hide away. The machined billet aluminum finish and clean overall profile reflect that intent. An integrated fuel pressure gauge is included, sized to match the compact footprint of the regulator itself, keeping the installation tidy without sacrificing visibility.
