Stock 1.8t Fuel pump specs ?

[Europotvin]

Hi fellow Audiziner's,


Ive been looking around the net for a couple of days, but cant seem to find any exact info. I want to know how many GPM or LPH the stock fuel pump on my 1.8t flows, and how much pressure it pushes ?

I think the correct part number is 8E0906087P.


Thanks !!!

Pressure is controlled by the regulator (in the filter on my car, maybe all B6. B5 had it on the rail). It's not super high pressure, maybe 4 bar (60psi).


They bentley had a flow test but I don't remember exactly. Maybe 1l in 15s (~1gpm, 240l/h). I don't remember if that is wide open, or past the reg.

Shouldnt matter as these pump at a constant voltage and amperage.The pump is not varied like on newer cars.

Ok, because I am putting a TDI in my B6, and I wanted to know if I could use the pump for a little bit while I finish every everything else (dont know If running Diesel in it will make it fail faster.)

I need around 180 l/h at around 10psi, so I guess ill get a adjustable regulator and bring it down to around 10 psi instead of 60 psi.

Ok, checked the bentley

the output with car not running (i.e. 12V battery) is minimum 375ml/15s
at 13V it is 450ml/15s

which is only 108l/h (@450ml/15s). Guess my guess was on the low side, although that is minimum, lower is a fail. Maybe actual output is higher.
