The primary rail mounts to the throttle bodies and feeds the four primary injectors on the supercharged H2. It is CNC machined from solid 6061 aluminum, anodized and laser etched, with three 3/4in-16 (8AN ORB) ports and four injector bores machined for 11mm upper injector O-rings. It is compatible with all fuel types including E85. Reaching it means pulling the intake plenum cover, which has fifteen perimeter screws, and the four velocity stacks, and the rail then mounts on new supplied screws rather than the four OEM bolts. Because the H2 runs its fuel lines on opposing sides of the engine, the feed uses a dual banjo adapter, which is supplied in the matching 20-1136-PK plumbing kit.
