Ok, got the truck to start. what i did was change the spin on filter and bypass the water separator, only because i could not find one. I tried pumping the primer and the same vacuum symptom was happening, sucking the primer back down? i ended up just for kicks cranking the engine and it started up. it started up again the next day, so i am thinking the water separator was clogged, i will put a new one in.

another symptom the truck has always had since i have owned it was, when you first start it up, for the first few seconds it runs ruff, like its missing, then it clears right up and runs perfect. only on start up? any ideas?

thanks.
