I'm bringing this over from the CUCV board on steelsoldiers.com
Truck is a 85 J code M1008 with 95xxx miles. Any help would be greatly appreciated.
I'm having some issues with my truck. If i drive my truck at a sustained speed over 45 or so it seems like its running out of fuel. It will kind of stumble and then catch itself and continue to do this until I slow down. When it does stumble I notice a small puff of black smoke though. I don't know if its overfueling causing the hiccup or if the pump catching back up is causing the smoke.... I replaced the fuel filter, checked for bad/worn lines, and put a new lift pump on it. It does it regardless of fuel tank level so its not the pick up. I pulled the return fitting of the top of the injector pump and it seemed to be stuck, so I played with it and got it to release and cleaned it the best I could. That made me think maybe it was getting to much fuel? Seems odd to say for a diesel. So now I think i'm looking at having the pump rebuild.
Any other ideas?
Is there anyone that you guys recommend to do this? Maybe someone near St. Louis that I could take the pump to. I really don't want to mess with the ebay crowd. Thanks
