Popping coming from gas tank when off

Any thoughts? No it’s not water dripping above or anything checked all that lol. Been happening for a few days now even when dry out.

Can you determine if it's outside or inside of tank.

It’s hard to tell the location of the noise from the video, but it sounds like the ticking from the exhaust cooling down. I’m sure it’s not that though if it’s a new noise that you’re noticing near the fuel tank.

Those frame rails look so clean!

My old ears even say like fuel sloshing and something loose in tank but I doubt that's what it is.

Like sneezy said exhaust cooling. Like maybe a heat shield or something like that expanding or retracting as it was hot and now cooling down.

That’s an interesting one. Is that right after driving? And I agree with @Sneezy your frame rails look good considering you’re in Buffalo.

I bought it in February brand new and this winter we haven’t even had one major snowfall event with the El Niño. The chassis likely won’t be challenged with any salt until next winter. Yessir this was recorded after driving this morning.

While it's happening, try sticking the emergency filler funnel in... it might be a semi-blocked breather or one way valve?

Sounds like exhaust heat shield cooling to me but if you just started hearing it for first time then maybe it is something more.

So I asked about when it happened so I could check today. I checked when I got to work and shut the truck off and again after I got home. All I had was the heat shield cooling noise which you can hear in your video. I did not have the much louder tapping/thumping. I can take a video tomorrow morning if you’d like. I have the 3.5 EB and 36 gallon tank.

I topped the tank off today and it’s silent so it seems gas tank related. It was below 1/4 when it started making noise. No clue, I’ll try what SilverPigeon said if it happens as it runs through the fuel. This truck has so many relays and crap running under the hood even when off it’s hard to figure anything out lol.

For what it’s worth, I’m at about 7/8ths of a tank. I can run it down and see if I can replicate it if you’d like.
