The new Radium Engineering fuel pump hanger has been redesigned for improved fuel collection and for ease of installation. It completely replaces the factory in-tank fuel pump module and allows 1 or 2 aftermarket fuel pumps to be used. The OEM level sender is retained in order to maintain factory functionality.
PREVENTING FUEL STARVATION
The kit includes a 1-piece anodized aluminum collector box that makes installation a breeze and keeps fuel trapped around the pump inlet(s). There is a 355 LPH 1-way fill valve incorporated in the bottom of the collector that allows fuel in, but not out. The collector box is constantly replenished with fuel returning from the pressure regulator.
PORTS AND FITTINGS
- The pump-out port is tapped with 3/4"-16 (8AN ORB) threads.
- The return-in port is tapped with 9/16"-18 (6AN ORB) threads.
VENTURI JET PUMP
- The OEM venturi jet pump in the return line creates a restriction that can impact fuel pressure reliability.
- Radium Engineering has redesigned the siphon system to eliminate this restriction but still effectively scavenge fuel. This means higher flowing pumps can safely be used without fuel pressure issues.
- Depending on fuel pressure, the venturi jet pump will consume 15-45 LPH. Take this fuel loss into consideration when sizing the fuel pumps.
- If it is important for fuel pressure to hold steady after the engine is shut down, a check valve is required. NOTE: The 20-0966-0X fuel hanger plumbing kits below come standard with a built-in check valve filter.
