gas tank pressure

  1. I just read a post about this over in the corral and realized that I have this problem also. I didn't really get an answer over there so I was wandering what you guys think. It seems that I get a lot of pressure when I unscrew my gas cap almost enough to blow it out of my hands. I stilll have my canister hooked up and I also have 190 gas pump. Is this normal?
  2. No it is not normal. You need to replace the fuel cap which has a vent in it and also check the line that goes to the carbon canister and make shure it is not blocked off.
