Product Description

CJ Motorsports fuel rails offer the perfect foundation for building your RX7 fuel system. CAD designed and CNC machined from 6061-T6 Aluminum.

The CJM primary rail includes -6an fittings on either end. The secondary rail includes a -6an outlet at the front, and a -8an inlet at the rear, but can ship with either a -8an inlet fitting or a -6an reducer inlet fitting. Optionally, the CJM Y-Port secondary upgrade features an integrated split for parallel plumbing to the primary rail.

Select your secondary rail with 2 fuel injector ports for use with the factory 13B-REW lower intake manifold, or 4 injector ports for an aftermarket LIM. Optionally, our 2-port secondary is available with an integrated fuel pulsation damper. The FPD upgrade is an OEM-style option that reduces fuel pressure oscillation and noise, flattening out the fuel tables during tuning and smoothing out part-throttle engine behavior.

Our v4 rail sets are offered in 2 colors. The rail spacers are offered in black or semi-polished set for 60mm or 48mm injectors.
