Specifications

Piston, not bladder

Most regulators use a rubber bladder that flexes, bounces and flutters under load, so pressure swings away from the target. The Hybrid Racing FPR uses a machined piston that moves smoothly, and its built-in damping keeps the gauge needle steady, so air-fuel ratios do not swing mid-pull.

Construction

The Hybrid Racing FPR body is machined from 6061-T6 aluminium with 304 stainless internals, hard anodised with Teflon impregnation against corrosion, and sealed with quad O-rings. It is compatible with E85.

What you need to know

The Hybrid Racing FPR is for return-style fuel systems only. It does not work with factory returnless systems such as the RSX, EP3, FA5 or FB6, which must be converted to a return line first. The kit includes the AN fittings for a -6 AN return system, works with up to -8 AN lines, and comes with a billet mounting bracket.
