[s-cars] RS2-related Fuel Pump Question

[Sean Douglas]

Dave:

As you know, I have the pinging problem too with a similar setup. My
fuel pump was replaced in May 2003 at Audi of Richmond (under warranty)
and the part number is 8A0 906 091G, they also replaced the resevoir it
sits in.

I replaced my FPR too as a preventative measure, maybe I'll look into
the fuel filter.
