Not fuel pressure. 89 4.0 auto 4x4. After a couple of miles my gas tank builds up a lot of pressure. So much pressure that it makes my fuel rail o-rings leak. When i take the gas cap loose it lets pressure out for at least 8 seconds! Ive replaced the cap. How does the rennix tank vent? If its through the charcol cannister im assuming that it is prpbally clogged. 242k on the jeep. Thanks in advance.
