gas tank pressuring up
 
i removed the emmissions box in my 82 grand prix. the gas tank vent tube was blocked off and then the gas tank was pressuring up alot and when i would undo the gas cap the tank would go back into shape and release its pressure.

i bought a new gas cap wich says its vented but the tank still pressures up.

what do u guys do when u remove your emmission boxs?

Why would you remove it?....you aren't helping performance any by doing so.

To be perfectly honest with you. I just drilled a small hole throught the cap on my brother-in-laws truck and never had the problem again.

i removed the emmissions box so the engine bay is cleaner looking and also i dont know how its supposed to be hooked up plus it would need all new hoses. plus i got no EGR thing on my intake or anything so i didnt see a point of putting it back on... the gas tank vent tube was also cloged up with rusty looking stuff that smells bad, very bad.

i never removed it for performance.
