Thanks Kday, I checked genuineaudiparts.com for the OEM pump but they don't have the RS6 in their catalog. I need to pull the pump and remove the protective sleeve to get the part number first. Of course, if you know of an easy way to figure out the part number, I would appreciate knowing how. I just didn't want to deal with the gasoline leak until I have the replacement part, so I left it hooked up to the pipes for now.
Also, does anybody know what pressure the OEM pump puts out? I kind of like the smaller pump from ECS tuning (both price and mounting configuration) but I am not sure if 3 bars would be too much with the original pipes. I called ECS but the guy on the phone was kind of clueless as to how well of a fit this one is for RS6. http://www.ecstuning.com/Audi-RS6--4...nce/ES2189784/
