This hose assembly is used to replace the last section of your fuel delivery to the rail on the 7m motor. This will allow removal and elimination of the Fuel Pressure Dampener and section of hose next to the intake manifold. This is the only feasible way to eliminate the FPD. The FPD is not really a restriction in the system, but many high-power builders like to remove the FPD for simplification of the delivery path. It looks great too! The kit has the fuel-rail fitting, the fitting for the mating assembly at the manifold, and a SS hose assembly with two add'l interface adaptors. It's pretty evident in the photo.
