Guess the vent was plugged

My Oliver 66 had been sitting in the shed since I put the corn planter away. When I parked it the float was sticking so I took the carb off and cleaned it before I started it this time. Before I put the gas line back on,I opened the shutoff to let a little gas out. All I got was a hissing and a little bubbling sound. It kept on for quite a while and I thought it was blowing out. I put my finger over it and it was sucking air IN. It never did quite quit til I loosened the cap. Must have been sealed up pretty tight to cause that much vaccum.

Flat sided tanks in cars can partially collapse! Condensed fumes suck in on the cap and make it seal even tighter! Neat discovery. JimN

Back in the 80's, I know of a car that the vent hole in the gas tank was plugged. The fuel pump collapsed the tank, the car was brought in, it would only hold a couple of gallons.
