I just spent the better part of 4 hours replacing both of the A8's fuel pumps. What. The. Frack. It's tank is shaped like a saddle. On each side of the saddle is a pump and each pump has a fuel level floater and an additional pump to pump gas to the other side of the saddle to keep the tank balanced.
This all wouldn't be so bad if you didn't have to crawl in the trunk to replace them but you do. Then there's the fact that one pump feeds the other and they are connected by 6 different hoses. To connect them there's a tunnel that runs in the tank, above driveshaft and you need to feed the hoses through it and reach in to grab them from the other side.
This job sucked but I got my A8 back so I'm stoked. Time for the Bimmer to take a nap.
