Pressurized gas tank


Recommended Posts

Hello all, 

I just took my car out and noticed when I went to the gas station and took off my gas cap the tank was pressurized. Anyone have this happen? I did some looking online and can't find anything for an old car. Mine is a 1971 Lemans Sport with a Pontiac 400 Stoker. No fuel injection. 

Thank you!

There is a vent cap next to where the fuel goes in. I took it off and ordered a new one. It was probably clogged.

More than likely the vent cap is the issue! Usually what you described is actually a vacuum, not pressure, but it happens so fast when you loosen the cap it seems like pressure.
