This universal inline fuel pump will fit most import and domestic vehicles. The fuel pump is usually mounted outside of the gas tank by itself, with another inline fuel pump, or as a booster for the existing in-tank fuel pump.
In a majority of cases, it does not hurt to install a high pressure fuel pump into a non-performance vehicle because most of the fuel sent towards the engine is unused and get sent right back to the gas tank via the vehicles fuel return line.
  • Superior turbine pump design virtually eliminates fuel pulsation
  • Bosch impeller ring provides smooth fuel flow
  • Precision, spin-balanced and polymer-encased armature reduces noise and vibration
  • Premium carbon brushes, utilizing advanced materials provides longer, reliable service life
  • Noise suppression coil virtually eliminates radio frequency interference

The Bosch 044 is one of the most popular external fuel pump upgrades for vehicle enthusiasts in need of high pressure fuel for their high powered engine. Bosch 044 fuel pumps mount inline (outside of your gas tank), most commonly as close to the gas tank as possible. 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.

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 an amazon 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

Bosch 044 fuel pumps are comparable to the Walbro GSL392 255LPH high pressure inline fuel pumps and will support up to 700 horse power. Can be used in sequence with an in-tank Walbro GSS340/GSS341/GSS342 or Bosch 040 fuel pump for even more support.
