[s-cars] Fuel pump

[David Giannandrea]

I bought the Bosch OEM from my favorite parts supplier, not Audi. Due to
connection issues I then bought another bosch from Audi. There was a very
noticeable difference in weight between the two pumps, the Audi version
being heavier.

I recommend buying the part from Audi. This was 5-6 years ago. My 93 S4 had
over 200,000 miles on the original fuel pump. I took advice from this list
that it was time to replace it. Other than that, it was still working fine,
maybe with a bit more noise than the new one, but without problems.

My concern with the replacement fuel pump was not with pressure rating, but
pressure rating combined with high flow. That specification is impossible to
determine from sales literature.

Just my experience on my high mileage urS4.
