Bosch 044 Fuel Pump 500+HP

Not rated yet

Bosch 044 Fuel Pump 500+ HP. These are notorious and have a great reputation, however lately we have seen them often eschewed in favor of the E85 Walbro turbine pumps, such as the "400/450/485 lph" pumps

This is the popular Bosch Motorsports "044" fuel pump, as used by Japanese European & Australian tuner shops, JGTC cars, Touring cars, almost all WRC cars, and many more. 

Quite possibly, the most popular aftermarket fuel pump. Capable of providing 300 LPH free flow and 200 LPH at 5 bar (or 72.5 psi) for up to 685 BHP. In comparison, the Walbro GSS341 255lph "high pressure" fuel pump can support 390 BHP 

Note: Values calculated at 12V, 3 bar (43.5 psi) base fuel pressure, 2 bar (29 psi) boost pressure, 1:1 fuel pressure regulator ratio. These are inline fuel pumps, we recommend they be installed between the factory (or another aftermarket) in-tank fuel pump, and the fuel rail. 

These may be installed in the fuel tank, but some custom fabrication will usually be required. Technically, Bosch Motorsport doesn't want you putting them in the tank. Not sure the reasons. In addition, feeding these inline pumps with another pump (in series) will boost the output of the Bosch 044 fuel pump even higher.
