PORTS AND FITTINGS
The end ports of this fuel rail are tapped for 8AN ORB. A center port for the factory fuel pulse damper is also included.
8AN ORB Adapter Fittings can be found HERE.
8AN ORB Direct Mount Regulators can be found HERE.
Fuel Pressure Gauge Adapters can be found HERE.
Appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.
This high volume fuel rail works on all 2ZZ-GE engines. Both ends of the rail are tapped to 8AN ORB female threads. These ports use positive o-ring seals instead of tapered pipe threads which commonly damage aluminum threads and lead to fuel leaks. The center port accommodates the 2ZZ-GE fuel pulse damper (not included) from the OEM fuel rail. This helps alleviate all high frequency pressure fluctuations.
The fuel rail was designed to clear the intercooler mounting boss (Exige-S/2-Eleven only) as best as possible without sacrificing fuel flow. Some grinding may still be necessary.
