My M998 was running like it was fuel starved, losing power at highest speed. At lower speeds, it ran fine. Parked it overnight and had a hard time starting it. Cracked the drain cock on the fuel filter, the engine died and will not start. No fuel spurting from the pump or filter while cranking. Therefore, I think I either have fuel line blockage or a bad pump. Perhaps both?
I have the rubber lines off the fuel (lift) pump. Should gravity allow fuel to just flow out of the lower line from the tank? It appears quite dry. Certainly nothing flowing out.
If I remove the fill cap on the fuel tank, should I be able to hear compressed air in the tank if I blow air back through that hose from the pump end? If the fuel line "sock" got sucked up, should I be able to blow it back open with compressed air through that same line?
Is there a location between the fuel pump and the top of the tank that I can break open the fuel line and see if I get any gravity flow? The tank is nearly completely full and I'd rather not dump or drop the tank just yet. I haven't crawled under there to trace the line back yet. Thought I'd ask first.
Thanks!
