You're correct. The fuel would be injected when its supposed to, but what it would do is any residual pressure left in the line would be bled off into the cylinder. You would have a strong odor of unspent fuel at the exhaust. I've seen them before to where you couldn't stand beside the truck for it being so strong. My guess is the seals in the pump are bad, and thats where your problem is. You have fuel in the top part of the p-pump, and oil in the bottom to lube the camshaft inside the pump. The return for the excess oil is dumped right back into the crankcase. It's an educated guess, although it might not explain the external leak though.Yeah , there is definetly lots of fuel in the oil. Hope it's not more than 10%. I'll get an oil analysis done to be sure.
There is a lot of fuel coming out outside as well. If it was an injector there would be no external leak correct?
