Radium Auto Fuel Pump Hanger - A90/A91 GR Supra

The Radium Engineering fuel pump hanger is an excellent solution for increasing fuel flow on the 2020+ Toyota GR Supra. The kit leaves the entire OEM direct injection system intact. However, it permits one additional independent 39mm fuel pump, specifically for auxiliary fuel such as port injection.

The entire OEM fuel system and its components are retained and operate exactly how BMW/Toyota intended. The OEM brushless fuel pump, fuel pressure regulator, filters, collector box, venturi jet pump and level sensor all remain in place. The Radium hanger installs alongside these components and adds a complete second fuel system for adding port injection. For a compatible B58TU port injection system, click HERE.

PUMP COMPATIBILITY

⁽²⁾Fuel pump filter socks for these pumps are included with the pumps.

Fuel pumps larger than 39mm such as Walbro F900002XX, Deatschwerks DW400, Bosch BR540, etc. are not compatible.

HOW IT WORKS

An additional fuel pump with a pre-pump filter sock is integrated into the OEM fuel collector basket. The fuel from this new pump is sent out of the fuel hat through a low-profile 8AN male adapter fitting.

This line must be regulated using a fuel pressure regulator (not included) and a low micron aftermarket filter must be installed downstream. These components are not provided in this kit but are available separately.

The returning fuel enters the fuel hat through a low profile 6AN male fitting. Fuel enters the OEM collector basket through a machined fitting assembly. Inside the assembly features a deflector that evenly disperses the fuel and prevents turbulence and unwanted foam. The direct injection fuel feed is retained and there are no fuel tank modifications required.

PREVENTING FUEL STARVATION

Several systems work together to move fuel into the collector basket and keep it full at all times. This ensures that the pumps have adequate fuel available, even during aggressive driving. The internal pumps are supplied with fuel from 3 different sources: the venturi jet pump fuel scavenged from the passive side of the tank, the returned fuel from the fuel pressure regulators (direct injection FPR and port injection FPR), and the one-way fill valve on the bottom of the OEM collector basket. This valve allow fuel in, but not out.

PORTS AND FITTINGS

The outlet on the fuel hat is female threaded for 8AN ORB (3/4-16 O-ring). A male 8AN low profile banjo fitting comes preinstalled. This can always be changed using any 8AN ORB fitting.

The return port inlet on the fuel hat is female threaded for 8AN ORB (3/4-16 O-ring). A male 6AN low profile banjo fitting comes preinstalled. This can always be changed using any 8AN ORB fitting.

The OEM direct injection pump outlet is an SAE quick connect to directly connect the OEM feed line.

ELECTRICAL

The custom designed stainless electrical studs easily handle the high current demand that compact multi-pin bulkhead connectors lack. These serviceable connections are hermetically sealed and impervious to all standard and exotic fuels. Non conductive anodized aluminum acorn nuts are provided to prevent any accidental short circuiting. Electrical hardware is included for the fuel pumps and OEM level sender. Furthermore, the in-tank wiring is insulated with high quality chemically resistant ETFE.
