1991 F350 7.3 idi : It has a new lift pump, new return line kit, new Motorcraft Glow Plugs, and all injectors have been externally cleaned, and all seem to work.
It was running smoothly UNTIL I hooked it to a large RV. After driving 15 miles with no problems whatsoever, I was faced with a semi-steep grade. The truck made it 1/2 way up the hill and immediately died. It had lost its prime. I primed it 3 more times on the way to the campground, and dropped the RV. Then headed home and had to prime it 3 more times just to get it home. Prior to this scenario, it was running perfectly for a full month.
How could it lose it's prime over and over?
I thought possibly due to the load, then I dropped the load and still it kept losing prime.
Ideas? Experience with this issue? Thanks for your assistance.
