Ran out of fuel on a busy highway in a lane of traffic. Cars speeding by dangerously close I needed to get to a side road so I took a bottle of Howe's lubricant I was carrying and put it in the tank. Got it running and off the busy road to safety before it died again. Help came and we put 5 gal in, it started and ran for maybe 10 seconds before dying again. I was close to home so a friend came and pulled me home. Filled the tank, changed the fuel filter and been trying to prime it for a couple of days now but it will not fire up. My questions are: Is the Howe's in the system keeping it from running? Had a Cummins before, do i need to crack open the fuel lines to bleed the air and or Howe's out like on the Cummins? Finally did I screw something up with the additive and what would it be? I'd deeply appreciate any help I can get. Thank you
