Which vehicles does this fit?

2003+ Nissan 350Z, Infiniti G35 and 2008 Infiniti G37. The 370Z uses a different hanger.

Should both pumps run all the time?

No. The pumps should be staged — the car should start, idle and cruise on one pump, with the second coming on only when demand requires it.

Do the dust seals go inside the fuel tank?

No. They are for the outer connector only. They are neither fuel safe nor watertight, so they serve no purpose in-tank.

What pumps does it support?

Walbro 450, 485, 525, 535 and 255, plus AEM and DeatschWerks pumps with 34-35mm diameter bodies.

Does it retain the factory fuel level sensor?

Yes, there is a mounting provision for the factory sensor, and a Venturi siphon jet assembly for the OEM fuel line is included.

Q: Is the relay harness specific to my car?

No. The same relay harness is used across every ASE pump hanger, and standard four-pin relay wiring is identical on any application.

How the pumps should be wired

Pumps should be staged, not run together continuously. The car should start, idle and cruise on a single pump, with the second coming on only when demand calls for it.

Relay harness

The ASE relay harness is not application specific — the same harness is used across every ASE pump hanger, and standard four-pin relay wiring is the same on any car.

Seals and connectors

Supplied dust seals are for the outer connector only — not fuel safe, not watertight, and not used inside the tank. The hanger uses Deutsch connectors; a full replacement connector kit is available separately.
