Working on a 2009 GMC C5500 with a 6.6L. The fuel tank on this truck is underneath the driver's side door/step. We've been searching for a replacement fuel sending unit with no luck. The GM number is 19168835 and the ACDelco number is MU1658, and have been discontinued through GM with no info as to what another option is. We're striking out through aftermarket, and short of trying to adapt something "universal", we're at a dead end. If anyone has had to replace one of these or has any insight on where we could find one, that would be much appreciated.
