I've got a 2012 and a 2011 CXU 613 with what appears to be the same problem no brake lights. Checked for power going to the brake switch under the dash drivers side foot well. No power. Checked fuse checked out OK. Ranba jumper wire to the switch and applied brakes lights worked. Any suggestions to were to look next.

In GA going to try and get it up to the Mack shop in Atlanta

Thanks

Any help here have a 2011 CXU 613 with a mp7 was driving when the hard dog came on said clogged fuel filter. Right after that truck shut down . Replaced fuel filter strated and ran for a few minutes. Fuel filter lost prime. Checked banjo fittings at pump and at the filter housing and on the plate. All clean . Reprimed and started truck smells thing would run till fuel in the filter was gone. Let truck sit over night started but again stopped due to no fuel . Any suggestions.
