fuel pump howl? video. vapors?

i was driving the whole day. then as im driving down the freeway today on a hot day . my rear seemed like it was howling. so i decided to record it, once again.http://youtu.be/aXrdNPdezmg


i took the gas cap off and air preassure came out. its normal, but not like today it was bad. u can even see the gas vapors for a long time. look at video carefuly plz. am i driving a timebomb? or poison?http://youtu.be/nzW4gNcZ0vA

also i turned on the switch to hear fuel pump, an it sounded realy realy loud. no normal at all. i could hear it from a mile away http://youtu.be/JZkYWZMyQmE

have a similar problem, too much pressure in the gas tank, my guess is that fuel lines clogged up, I put 2 cans of seafoam in, so far so good

Mine does this as well, it's even scarrier when you're filling up after driving for a while, the pressure builds as the gas enters and it sounds like it's going to start spraying everywhere or explode.

Seems to be a common issue lately. Check this thread on the TPI board:
