The fuel injection supply manifold delivers high-pressure fuel from the vehicle fuel supply line to the six fuel injectors. The fuel injection supply manifold consists of:
- an integrally molded fuel pressure regulator cup with retaining clip.
- two molded thermoplastic composite tubes with one fuel injector connector for each fuel injector.
- a fuel pressure relief valve for diagnostic testing or field service fuel system pressure bleed-down.
- mounting attachments which locate the fuel injection supply manifold and provide fuel injector retention.
