Challenger Posted April 2, 2013 Share Posted April 2, 2013 If the lightening bolt only comes on with the new sending unit I would try another new one.

bbigrig Posted April 17, 2013 Share Posted April 17, 2013 For one of my CXN's I was given 2 defective fuel senders out of the box. 3rd one seemed to be the charm. Seems to be a common issue with the supplier of these new tank senders.
