Radium Fuel Pump Hanger - Toyota Supra A80 JZA80 (1993-2002)
Application: Toyota Supra MK4 (JZA80)
Part Type: Billet aluminium fuel pump hanger - pumps not included
Part Number: 20-1510, 20-1511, 20-1512
The Radium Fuel Pump Hanger allows one, two or three aftermarket fuel pumps to be run in the stock MK4 Supra fuel tank without permanently modifying the fuel access cover. Pump outlets merge into a single 10AN billet collector, and barb fittings are included to reconnect the OEM return and vent hoses.
A redesigned venturi jet pump scavenges fuel from outside the sub-tank and feeds the pump inlets directly, addressing the weak starvation protection of the OEM system without restricting the return line. A high-flow check valve on the merged outlet holds pressure after shut-down, and anti-rotation stainless studs, non-conductive acorn nuts and ETFE-insulated wiring handle the electrical side.

Important Notes
- Fuel pumps are not included
- AEM 50-1230 / 50-1235 pumps have no check valve - each requires one 20-1533 check valve kit
- Ti Automotive E5LM pumps (20-1511) require one 20-1534 check valve kit per pump and a Ti Automotive BKS1001 controller
- Protec 11928, Fuelab 49614 and DeatschWerks DW810 pumps do not fit the included strainer and require the 13-1187 base
- The venturi jet pump draws approx. 15-45 LPH of pump flow depending on fuel pressure - factor this into pump sizing
- Single-pump setups can reuse the OEM controller wiring, but upgraded wiring is recommended (one wiring kit per pump)
- The optional 20-0415 plumbing kit is designed for the Radium 20-0215 fuel rail and is not compatible with the stock 2JZ rail
