Radium Engineering Fuel Pump Hanger | 2020-2026 Toyota Supra (20-0760)

The B58's direct injection maxes out before big boost does, and port injection needs its own pump.

The Radium Engineering Fuel Pump Hanger for the MK5 Supra is an excellent solution for increasing fuel flow on the 2020+ Toyota GR Supra: the kit leaves the entire OEM direct injection system intact while permitting one additional independent 39mm fuel pump specifically for auxiliary fuel such as port injection. Drop-in installation, anodized aluminum construction, high current electrical hardware, fuel resistant tubing and wiring, and gasoline, ethanol, and methanol compliance throughout. The modification is NOT compatible with the larger 39/50 DCCS pumps (Walbro F900002XX) but has all the provisions for a brushless pump. Pumps sold separately.

What You'll Feel

• Port injection fueling capacity added while the factory DI system runs untouched
• Starvation-proof supply, the collector basket fed from three sources during aggressive driving
• Full pump power through the high current electrical hardware
• Flex fuel and methanol readiness from the compliant materials
• A drop-in install in the factory hanger location

Features

• Drop-in hanger for the 2020+ GR Supra (A90/A91); adds one independent 39mm auxiliary pump
• OEM direct injection system fully retained; auxiliary pump serves port injection duty
• Collector basket kept full from 3 sources: the venturi jet pump scavenging the passive tank side, returned fuel from both the DI and port injection regulators, and the one-way fill valve on the OEM basket that lets fuel in but not out
• Port injection feed port: 8AN ORB female with male 8AN low profile banjo preinstalled; return port: 8AN ORB female with male 6AN low profile banjo preinstalled (both changeable via 8AN ORB fittings)
• Brushless pump provisions; NOT compatible with 39/50 DCCS pumps (Walbro F900002XX)
• Anodized aluminum, stainless hardware, fuel resistant tubing and ETFE-class wiring; pumps NOT included

The Details

The A90's fueling ceiling is the DI system's, since the factory high pressure pump and injectors run out of duty cycle as boost climbs, and the tuning world's answer is supplemental port injection with this hanger as its foundation: an independent pump feeding a B58 port injection rail like Radium's 20-0753, regulated separately, blended by the fuel controller. The starvation architecture matters at track pace, with the venturi scavenge, dual regulator returns, and one-way basket valve conspiring to keep the collector full while the chassis works. Pump selection follows the 39mm standard with brushless provisions ready, wiring runs through the high current hardware, and the 20-0761 plumbing kits complete the path from hanger to rail.
