When I start up the van I hear a clicking by the rear drivers side tire, I then hear a hissing from pressure being built up in the gas tank, when I shut the van off the clicking starts again like it is releasing the pressure. If I take the gas cap off in between all this there is a lot of pressure that is released from the gas tank, I have never heard this from any vehicle. Is this thing going to blow up?
why is there pressure in the gas tank and clicking by the rear tire? on 2001 Chrysler Town & Country
