Radium Engineering Fuel Pump Hanger for 2013 to 2020 Scion FR-S / Toyota 86
The Radium Engineering Fuel Pump Hanger has been redesigned for improved fuel collection and 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. Furthermore, the collector box is constantly replenished with fuel returning from the pressure regulator.
NOTES ABOUT THE PLUMBING PORTS AND FITTINGS
The pump-out port is tapped with 3/4"-16 (8AN ORB) threads. The provided fitting is an 8AN ORB to 8AN Male
The return-in port is tapped with 9/16"-18 (6AN ORB) threads. The provided fitting is an 6AN ORB to 6AN Male
NOTES ABOUT THE VENTURI JET PUMP
The OEM venturi jet pump in the return line creates a restriction that can impact fuel pressure reliablity.
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.
NOTES ABOUT FUEL PRESSURE
This system eliminates the OEM fuel pressure regulator inside the stock unit.
This system requires the use of an aftermarket fuel pressure regulator.
A fuel pressure regulator is included in the plumbing kit listed below.
NOTES ABOUT FILTRATION
1. This system eliminates the OEM "post" fuel pump filter. A low-micron aftermarket fuel filter should be installed downstream to protect the injectors from debris.
2. A post-pump fuel filter is included in the plumbing kit listed below.
