COMPATIBILITY 2020+ Toyota GR Supra (A90/A91)   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)   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. NOTE: 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 (shown below). Inside the assembly features a deflector that evenly disperses the fuel and prevents turbulence and unwanted foam.  Instruction PDF
