I'm really surprised nobody else has answered you yet.

I assume the air you are seeing is in the clear plastic filter right before the injection pump? If that's it a little air is normal in it, just a few bubbles. If the car starts it should be able to purge any air that shouldn't be there by itself unless air is constantly being reintroduced. I would think air would make it run really rough if that's the problem too. Have you been able to determine if the primer pump is leaking still (other than when you pump it)? Also if it's the old style primer pump (white plastic top)you have to screw it back in to lock it closed I think and unscrew to pump, the new style (black top) you just push to prime.

All of that said it does sound like raw diesel in the exhaust or water getting into the engine (have you looked at the oil and the coolant level?) What does the smoke smell like? I really don't have any other thoughts, there are a lot of guys that know 100X more than I do about these cars maybe one of them will jump in soon. Good luck.
