This Bosch 044 fuel pump easily supports 600-700 horsepower applications. Quite possibly the most popular aftermarket fuel pump. Can be used in series with an intank Walbro fuel pump (or better yet a second one of these in-tank) for ultra high pressure applications up to 150PSI. Can also be used in a pair for setups well over 1200 horsepower! See related accessories for parts to convert this pump into an in-tank submerged pump for a stealth high flow single pump application that supports up to 700HP. AUTHENTIC EUROPEAN MADE, NOT A CHINA COPY.
Spec Info: 300 LPH free flow and 200 LPH at 5 bar (or 72.5 psi) for up to 685 BHP. In comparison, the Walbro 255 "high pressure" fuel pump can support 390 BHP. Values calculated at 12V, 3 bar (43.5 psi) base fuel pressure, 2 bar (29 psi) boost pressure, 1:1 fuel pressure regulator ratio.
The Bosch 044 Pump (this one) is for use with external mounting & comes with a threaded inlet for adapting a feed hose/line.
