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 auxillary fuel such as port injection. NOTE: The modification is NOT compatible with the larger 39/50 DCCS pumps (Walbro F900002XX) but does have all the provisions for a brushless pump.

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.
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.
