 :) i'm not that good with a comp yet.
there is still a checkvalve in the pump body. it is stuck and you can't get to it without destroying the pump body. you need to soak it for a couple of days, then work at it like i said. even worn out old pumps will still pump oil. the only reason these type do not pump, is one or both of the checkvalves is stuck closed or open. the way you were describing about the 'bubbles' coming out of the tanks vent pretty much tell me the 'input' side of the pump is stuck open.

mcculloch power mac 380.
when I grow up, i wanna be an adult.
