These plumbing kits integrate with Radium’s in‑tank fuel hanger to provide everything needed to route fuel from the tank to the rail with filtration and pressure control. With two filter options available.
Key Features (Both Kits)
-
8AN PTFE high-pressure fuel feed line routed around the rear of the fuel tank to a billet-mounted filter in the original location.
-
Fitted fuel filter with your choice of stainless or microglass media.
-
8AN PTFE feed line carrying fuel to an aftermarket RA‑series fuel pressure regulator (FPR) under the right-hand strut tower.
-
From the FPR, a second 8AN PTFE feed line runs to the front port of a dead‑head fuel rail (rail sold separately, e.g. Mazda B6 or BP rail).
-
The OEM fuel feed hose is retained and repurposed as a high‑flow return line connecting directly to the FPR.
-
A fuel pressure gauge port is built straight into the feed line for easy adjustment.
- A 10‑micron stainless steel filter element for durability and reusability.
- A 6‑micron microglass element for finer particle trapping and improved flow.
