Radium: FPR Kit 99-05 Mazda MX-5 RA-Series
This kit features a new adjustable fuel pressure regulator (FPR) that is compatible with all fuel pump hangers including the factory returnless system found in the NB chassis. As shown below, the FPR is mounted near the EVAP charcoal canister using OEM threaded studs.
The OEM fuel feed line from the fuel pump to the fuel filter is reused and unaltered. However, two new 6AN fuel lines are provided to and from the FPR.
A fuel pressure gauge mounts adjacent to the FPR on the feed line for easy adjustment. A stainless steel SAE quick connect plug is provided to block off the "TEE" on the OEM feed line.
