Re: Gas tank vacuum
No it should not be under vacuum your gas cap should be vented

Re: Gas tank vacuum
If it helps any, I order and received one from LMC last week. It is a vented one.
Fram part # PRG-23. I bought two locally one from Oreilys and the other from Car Quest. I told them vented gas cap. Well you guessed it, both were non-venting. Good luck! Keith |
