Pressurized gas tank
I fixed my gas fumes into the cabin problem with a new gas cap but that led to a problem with pressure building up in the tank.
So I replaced the roll over valve and the ventilation valve but I still get pressure building in the tank. There are no visible kinks in the hoses. Is it possible for the charcoal cannister to fail and clog up so that fumes do not pass thru? What would be the next logical step in checking this? I guess the good news from this is that my tank does not have the dreaded cracks at the top since it is passing the pressure test. Any thoughts? Thanks, Jon

My 951 did the same thing. I suspected that a valve somewhere in the emissions system had failed allowing the fuel tank to become pressurised. I ripped the whole lot out and the problem was fixed.
