north east IN
My semi converted to a straight truck started dying like fuel filter plugged. Stop and change filter and it would run ok for 2 hours then found out let it set 1 hour and it would be ok for 2 hours. Driving down the road it was ok but get out into the field chasing the chopper it would stall again. Took it to the fix it shop twice and they could not get it to act up. Then it started working ok and got all my custom work done then got home and it started again. I put a vacuum gauge on the fuel line and when it started acting up it was pulling 15 to 25 pounds vacuum. Took the fuel tank off and this is what we found it came off the fuel gauge float. Driving down the road it would lay there ok but when out in the field it would role in front off the fuel pickup and get sucked fast.
