Bosch Motorsport Fuel Pump 5 Bar High Pressure Inline
The Bosch 0580254044 pump can no longer be manufactured. The tooling and equipment was old and it was not feasible to be replaced. Bosch however, has designed an alternative that will have some technical differences but the performance will be similar.
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. Feeding these inline pumps with another pump (in series)- will boost the output of the Bosch 044 fuel pump even higher.
