Manufactured with a large 0.69" internal bore, the fuel rail can support all necessary engine power requirements. They are CNC machined from extruded 6063 aluminum, media blasted, black anodized, and laser etched for a high quality surface finish. Like the OEM fuel rails, the injector bores are 14mm ID so factory injectors are permitted. If purchased after July 2017, there is a provision to reuse the OEM injector clips (shown below).
This kit is compatible with all fuel types including popular alcohol mixtures such as E85. The OEM insulating spacers (Honda P/N: 16638-PNA-000) are reused and phenolic washers are included to thermally insulate the fuel rail from the aluminum intake manifold.
This part only includes the fuel rail and the mounting hardware making it ideal for custom applications.
-Black Anodized Laser Etched Aluminum Fuel Rail
-Stainless Steel Mounting Hardware
-Phenolic Thermal Insulating Washers
FUEL PULSE DAMPER
Do I need a pulse damper? The opening and closing of the injectors creates pressure pulses in the fuel rail, which can lead to unstable fuel pressure. In order to achieve a safe and consistent rail pressure, pulse damper(s) should be used (especially with high flow injectors). The internal diaphragm will absorb oscillation pulses and stabilize fuel pressure. This correction can be measured throughout the RPM range and can often help an erratic surging idle.
If equipped, the OEM fuel pulse damper (shown above) can be reused with the Radium 14-0278 adapter fitting.
The Honda pulse damper and Radium pulse dampers (FPD-XR shown below) can be put on any of the fuel rail ports.
