Okay guys I need help on a reoccurring issue I'm having...
1988 international s1900 with a DT466
Dump truck
I recently purchased this truck and it broke down on the way home. I know the previous owner and he's a trustworthy guy and he says he did not have this issue prior.
Breakdown #1
15 Mile road Trip. Broke down at Mile 13. Crank no start, no fuel. Tank full
Dragged it home, drained all the fuel out of it put fresh fuel in and changed the fuel filters which were nasty. Bled it all out. Started right up.
Breakdown #2
Thought it was all good to go. Headed to the fuel station to fill her up.... Made it 3 miles. Same crank no start. No fuel. Dragged it back home. Checked the fuel filters. They had no diesel in them. Suspected a clogged supply line. Blew backwards through the supply line. No restriction. Then I clamped off the vent hose to the fuel tank and pressurize the fuel tank with shop air. Fuel pushed through the supply line no problem. I filled the fuel filters with this procedure. Re bled the system. Started right up.
Breakdown #3
This time I was cautious and only drove the truck around the farm. Sure enough it broke down again and this time I went directly to the fuel filters. When I spun the first fuel filter off there was a vacuum on the filter. as soon as the o-ring cracked open you could hear a rush of air being pulled in. Of course the filters were empty. I needed to use the truck to move some stuff on the farm so I just pressurize the fuel tank again to push fuel into the filters and rebled the system. Started right up.
Anybody have any ideas where to look next? I'm thinking maybe a restriction in the filter housing itself????
