Radium Fuel Pump Hanger Suit Walbro 460/525/535

Important Notes: Aftermarket fuel regulator required, sold separately. Aftermarket fuel filter required, sold separately.

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. Part number 20-1073 is specific to the 12-21 Toyota 86 and Subaru BRZ fuel tanks.

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 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, install one of these CHECK VALVES somewhere in the fuel system.

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 add-on plumbing kit listed above.

NOTES ABOUT FILTRATION

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.
A post-pump fuel filter is included in the add-on plumbing kit listed above.

NOTES ABOUT WIRING

Single fuel pump installations can re-use the OEM fuel pump controller wiring.
Radium recommends upgrading the wiring to ensure the pumps are operating at their full potential.
Universal fuel pump wiring kits can be found separately in the add-ons above. Select one for each aftermarket fuel pump used.
