Bosch High Performance 044 Fuel 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 255 "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. In addition, feeding these inline pumps with another pump (in series), will boost the output of the Bosch 044 fuel pump even higher.

806/23/2010Seems alright claims it flows more than the walbro's and stock denso's in supras. I mounted externally and it's the loudest thing on my car besides exhaust. Not bothersome loud though.
