2003 chevy suburban gas tank pressure build up
trying to figure out why my 2003 suburban builds up so much pressure in the gas tank. Its been so bad that it wouldnt start and i had to remove the gas cap to let pressure out in order for it to start. Also if it gets below 1/4 of a tank it gets vapor locked? Any ideas would help alot.
