My 60 has been getting pretty bad about pressure in the gas tank. Went to church Sunday(about a 5 minute drive) and when I came out afterward there was fuel dripping out of the both sides of the fuel filter where the hoses connect because of the pressure. The hoses clamps are tight. I kinda thought the heat might be making things worse but it was only in the mid 80s. Also fuel in the tank gurgles almost everytime I drive now so I've been going to the gas cap and letting pressure off whenever I get anywhere because I dont want my new tank to get ruined. When I get home I'll remove the gas cap and lots of pressure will release but I can go back 10 minutes later remove the cap and its has generated more pressure again. The truck has been desmogged and I connected the fuel vapor hose to the other port on the charcoal canister without the check valve and I thought that helped for a while but its getting pretty bad. I'm not sure I wanna drive until I get some idea what to do about it. Any ideas on what I should check or why it builds so much pressure?
