My Type44 Audi 5000CS Turbo Quattro wa having a problem where it would stumble under high load.

This car uses the old Bosch K-Jetronic Lambda fuel injection system. As such, fuel pressure and flow are critical for proper operation. The aftermarket fuel pump the car has was giving not quite half the required volume!

Thankfully, I was able to get an OEM fuel pump for not too much $$, and the install process wasn't too hard!
