High Pressure In Gas Tank

[John M.]

My '85 seems to have a lot of pressure in the fuel tank. When I go to remove the cap, air escapes for a good 10 seconds and I really have to hold the cap. I don't know if this is normal, as my '74 has no pressure. I have the factory service manual, but it seems pretty vague. I've replaced the vapor canister, the vacuum valve, and the rubber hoses. How would I check the purge canister solenoid. Any suggestions would be appreciated.

My 70 and my 85 retain a good amount of pressure that is released when I remove the gas cap. They both have sealed gas caps that work.

Just make sure you're not smoking when you remove the cap!!!

Thanks for the responses, it looks like the valve is stuck.
