Gas tank noise

A few minuets after I park my jeep I hear a noise like a can pop. I think it is my gas tank. Is it pulling vacume and then letting off after I stop the engine? Is there some sort of vent that may be clogged?

Re: Gas tank noise

very interesting ... has your car ran on E a lot of times ... sometimes it can be the fuel system because it's pressurized and if you run it low for a while i mean a while there maybe some faults but I'm no mechanic and this is just taking a shot at the problem

Re: Gas tank noise

my pops old caddy did this.

when i used to ask why it popped like so, he would say its combustion issue. build up of carbon causes it.

side not- that caddy had a corvette engine in it!!! lovely car-

gl with ur issue- i took a shot in the dark about it-

its just something that happens. if you look at it after you stop (under the passenger side) it will be red hot, once it cools it will pop. mine heated and cooled too much and blew out in the spot when it got red hot.

Re: Gas tank noise

Mine did the exact same thing as well. What i dont get is the muffler blew out at 29k miles on the jeep... I took it to the dealer and they were like yeah looks like physical damage ( never took the jeep off road at this point) and would not replace it. Took it to three separate muffler shops, all said that it blew out and Jeep should warranty it. Ended up getting a dynomax anyhow but all in all, WTF, mufflers should not be blowing on a freakin' couple year old vehicle ( at that time). Just a quick vent.
