Radium: FUEL HANGER PUMPS NOT INCLUDED : Toyota GR Supra
OVERVIEW
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.
The following components are retained and operate exactly how BMW/Toyota intended:
-OEM brushless fuel pump (for direct injection)
-OEM fuel pressure regulator (for direct injection)
-OEM pre pump filter (for direct injection)
-OEM post pump filter (for direct injection)
-OEM fuel collector basket (for starvation protection)
-OEM venturi jet pump (for saddle tank crossover)
-OEM fuel level sensor (for fuel gauge)
FEATURES

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.
