Bosch Motorsport Replacement for 044 Electric Fuel Pump

Bosch Motorsport replaced their popular "044" fuel pump with this revised design. This high-flow pump is commonly used in aftermarket racing fuel systems and fuel cells. High flow rate meets your fueling needs up to 685hp. Up to 300l/hr and 200l/hr at 5 bar (72.5psi).

This new version is part # 0580464200 (0 580 464 200) and replaces discontinued Bosch part # 0580254044 (0 580 254 044).

Inlet: M18x1.5
Outlet: M12x1.5

Outlet fitting:
If you are using an outlet fitting that is not the factory Bosch check valve that comes with the 044, you will need to buy an M10 x 1.0 threaded fitting to screw directly into the new pump

Inlet Fitting:
The adaptor that comes with the pump screws into the inlet which makes it an M18 x 1.5 which is the same size as the 044 original.
If you don't want to use the adaptor, you will need to buy an M14 x 1.5 fitting to screw directly into the inlet of the pump

Adapter Sleeve:
The pump housing is smaller diameter than the old "044" design. The old unit was 60mm diameter, so Bosch includes a spacer sleeve to fit around the new 52mm housing. This adapter allows for proper installation when upgrading from the old "044" unit.

This is a universal fuel pump that requires custom mounting and fuel lines. Typical applications include full race cars with fuel cells or other cars that need additional fueling in addition to the stock fuel pump.
