Hello I have purchased a 1995 6.5 TD Had the truck for a week and it ran great. This past Saturday i was having a loss of power. Truck won't go over 35-40mph. I changed the fuel filter out. Still no better I then noticed I wasn't getting fuel to the filter. I changed out the lp this morning and now have plenty of fuel and the truck starts up and idles I can rev the engine between 1800 to 2800 rpm in Park with problem. As soon as I take the truck on the road and get on it. The truck goes when I let off the engine dies.. Any ideas?
