What is this box and why is the top wet with gas?

[Mean_Green]

Filled with gas a week ago and it's been parked since. Much warmer today than back then, garage is hot. Notice faint smell of gas and found a small spot on the garage floor, then this. Wiped it with a paper towel, but it kept weeping from that center hose. Removed gas filler cap and a loud hiss began as it vented. Weeping stopped.

Vehicle started and ran fine.

Maybe just too full on a cold day and now the hot day is having an effect?

I hope.

Nawh, something else going on.

The plastic nipple coming up out of the box is broken. Not sure if it was, or I did it messing around. There is a white/beige e-clip looking thing on the elbow, but I can't see how to release it. If I could get that off, I might be able to JB the nipple temporarily until I can get to the next step.

I'm guessing this is the box: https://www.amazon.com/911-297-Compatible-Chevrolet-Silverado-1997-2002/dp/B0DFYCXYC7

There should never be liquid fuel in a charcoal canister -- vapors only. When filling the tank, is more fuel being added after the pump first clicks off? If so, that can cause the fuel to overflow into the canister, and that can destroy the canister's ability to store vapors. Or maybe it's being parked nose-down on an incline, allowing fuel from a full tank to migrate through the evap lines.

 

[Mean_Green]

Neither of those. I may round up to the next whole dollar, but that isn't much.

How does that clip release?

I'm not familiar with those, but one of the other OBS members may know.

OK, so you squeeze the clip instead of trying to retract/remove it like a normal c-clip.

But the nipple fully broke off now before I could fully remove the elbow ... it was cracked most of the way through, which just might be part of my evap leak code that keeps poping the CEL.

I may try to JB it tomorrow, or just order a replacement.

So, is this why the canister filled with gas, or is there something else?

When you fill your tank with gas to let it click once only or do you keep adding gas after the click? If the later then you may have forced gas into the canister.
