What makes Radium FPDs unique?
Along with having the flexibilty of using common fittings, Radium Engineering FPD's use a vacuum/boost reference port which allows for proper fuel pulse damper performance even at elevated fuel pressures. This becomes essential for boosted systems that use a 1:1 rising rate fuel pressure regulator.
What is the difference between FPD-R and FPD-XR?
The FPD-R (green top) is slightly shorter than the FPD-XR (black top) allowing it to be used in space-contrained applications.
FPD-R base pressure requirement = 40 - 70psi (static)
Male fitting seals using a FKM O-ring.
Even after tightened the newest 8AN ORB dampers (20-0776 and 20-0777), will swivel permiting the vacuum port to be clocked 360 degrees.
This product is safe for use with all fuel types including alcohol blends such as E85.
