With a full tank of gas only. Could this be just the gas cap or maybe something more serious. 99 Dogde Ram

There's probably nothing wrong. When does it happen? Right after you fill it? Days after you fill it? What's happening?

hey Bleeddodge do you think that the breather on the gas cap isnt working properly?????

No.

This usually happens right after I fill up. Then will continue for a day or so depending on how much gas I run out. I think it usually stops after I burn about 1/8 of the tank.

When it first started I would not fill the tank up all the way and would not have this problem.

I can't explain it any better because to me it sounds like a gurgling or bubbling sound. This just started about a month ago. Never really heard it before but may not have paid enough attention.

What do you think bleed Dodge?

I don't think it's anything to be worried about, I don't know why you call it a problem. It doesn't prevent the truck from running or anything right? Maybe you have fish in your tank? LOL!

I don't believe there is cause for concern. If it bugs you that badly, just don't fill the tank so much.

If something actually does go bad as a cause of this, let us know. I know I've never heard of this before...
