Product Description
The ASE V2 twin fuel pump hanger is for IS300 and Altezza owners building beyond the limits of a single factory-style pump arrangement. It replaces the in-tank hanger with a setup that can support one pump for a simpler build or two pumps for a higher-output gasoline or E85 fuel system.
The hanger uses stud connectors for the electrical load of high-amperage pumps, an integrated venturi pump bracket, and AN or banjo connection options to suit the rest of the plumbing. The 8AN feed and 6AN return configuration has been tested above 1,200 horsepower, making this a real foundation part for a turbocharged 2JZ-GE or engine-swapped IS300 build.
Staged Twin-Pump Setup
ASE recommends staging the pumps instead of operating both full time. The car can start, idle, and cruise on one pump, with the second activated only when fuel demand requires it. This helps reduce fuel temperature and unnecessary pump wear during normal driving.
Before You Buy
Choose the fitting option that matches your fuel lines and confirm the pumps, wiring, fuel-pressure regulator, injectors, and ECU strategy are sized as one system. The optional relay harness is not vehicle-specific and uses standard four-pin relay wiring. The supplied dust seals are for the external connector only; do not install them inside the fuel tank.
