My 1989 Mercedes 260 E is bairly working but with 250,000-300,000 miles(odometer broke) I wasn't suprised when one of my fuel pumps broke, and the other one started leaking, my freinds and I are planing on just fixing it ourselfs, so it can fail smog. Where are the fuel pumps located?

 

Under the car, right (passenger)side, in front of the right rear wheel, hidden by a black plastic cover.
