Any one know the Bosch fuel pump part number.

058 0254 044

thats good. same unit as my mates are using in the high powered cosworths.

Mine was 90 quid new from ebay.

Cool

Is this S4 or RS4?

it can be used in both, it is an after market item

Ok, so how does it compare to the stock ones? I believe that the stock S4 pump does not flow enough when upgrading with K04s. How "far" does this one keep up?

Is this the pump needed

Bosch 0 580 254 044 Inline Fuel Pump

Bosch 044 fuel pumps mount inline (out side of your gas tank), most commonly rear center under your car or truck. Each Bosch 044 inline fuel pump provides 300LPH of flow and operate at 72.5 PSI. Bosch 044 fuel pumps are comparable to the Walbro 255LPH high pressure inline fuel pumps which can both support vehicles for up to 600-700 horse power. Can be used in sequence with an intank Walbro or Bosch 040 fuel pump.

Bosch 044 Fuel Pump Specs:
Bosch Part Number: 0 580 254 044
Minimum Current: 12 Volts
Operating Pressure: 72.5 PSI (5 Bar)
Minimum Flow @ Outlet: 80 GPH (300 LPH)

that is the one most people use

many thanks

isnt there also an intank version? or have i got it mixed up.

thats the 040 not the 044

My 044 is mounted in-tank. I used the V8 Audi 80 strainer and basket.

Sorry for the bump, but could you clarify if its ok to mount a Walbro 255lph inline pump intank in place of the stock S4 pump?
