The JSP Billet B-Series fuel rail is finally here. Most people upgrade their fuel rail as a means to increase fuel flow and adapt aftermarket fuel lines or gauges. Up until now most options are either bulky and boxy extrusions, or composite designs that don’t match the classic look of the B-Series engine.
Our goal was to create a simple and unique OEM+ design that compliments the OEM design while adding the performance features you need. The thru bore is 1/2” for high flow needs. The ends are both -8 ORB for aftermarket fuel fittings. However the rail is slim and adapts the OEM fuel pressure regulator in a near stock location on OBD1-2 engines. If you decide to have a remote mounted regulator, or want to mount an aftermarket regulator to the end of the rail, we have tapped the fuel port for the regulator so you can seal it with the included 1/8” npt plug. Each rail includes one -8 orb port plug as well.
Please note : This does not work with the factory fuel feed line. It requires the use of AN or similar fuel fittings and lines for the feed.
