There used to be a thread at http://www.bonnevilleclub.com/forum/viewtopic.php?t=71718 that detailed the process for replacing the fuel sending unit wiper arm. It seems to be dead now. Does anyone know where else I can see that information?
I also had that page bookmarked waiting to fix my fuel level sensor. I ended up at Rock Auto and got the arm he talked about- but was attached to the float. The part cost about 92.00 and was simple to replace. Basically unplug the old one and plug the new one on. If you are interested, the part is in the catalog under Fuel/Air then under fuel pump. Mine was SK1035, but there are 2 designs depending on VIN.
