I have a 2004 Dura Max 6.5 deisel with the Allison trans. I can not get it to hold its fuel prime, Ive changed out the fuel filter with new O rings on the filter, and used the onborad manual fuel prime pump, but still cant get it to hold its prime, once its started, it only runs a few minutes and its back to primeing again. Any ideas?
