What engine ? Cummins ? I had issue with the fuel solenoid on mine one time. Just died on the road. Had to zip tie it to make it run and cut it to shut it off. A previous thread about solenoids and a cheaper source. Not sure this applies to your situation and do your own homework but looks like good cost savings.
