Designed for K-SWAPPED Vehicles.

The fuel rail includes a specially designed fitting that can be used to mount the OEM damper in the factory location.
Most people remove the factory rail and the pressure damper without knowing its purpose.
It is actually on the rail for a reason. The purpose of the stock fuel pressure damper is to dampen the minor
fuel pressure fluctuations that are caused by the pulsing of the fuel injectors. This is known to cause small air
bubbles in the rail, which can starve the injector. The pulsation damper acts as an accumulator to smooth out these
pulsations, ensuring more accurate and constant fuel pressure.
The optional 6AN or 8AN center port fitting can also be used as the fuel feed on stock or all motor engine set-ups
to hide or “tuck” the line for the very popular stealth look.
Another common setup for high HP is to use a dual-feed system on both ends of the rail, with a center return.
