Gas spurts when filling up (2 Viewers)

[Seabert]

Hi mud, need some help here. Like many others, I had the hissing and pressure issues with my fuel tank. I swapped my charcoal canister with the VC 120 a while back which eliminated the hissing completely and was able to fill up my tank again with no issues. I thought I was in the clear!

I started having little dribbles when filling up and thought nothing of it, but lately it's been getting worse. Also have been questioning if I've been filling up to full. I've think that my fuel gauge may not be accurate. There's no hissing or vacuum when I go to open the gas cap. Any ideas on where to start?

What does this mean-"having little dribbles"? Gas is leaking somewhere?

Sorry for not being clear, I meant gas dripping from the nozzle as I’m filling up due to what could be back flow, positive pressure, or maybe back splash?

Gotcha, thanks. Yeah, I don't know. Possibly a clogged vent somewhere?

I've had that happen a few times also but literally like shooting out while filling

Replaced mine with a VC120 probably 5 years ago. Maybe just due again idk
Now I just fill on the slowest pump setting

I had that a moth ago when I drove cross country. Basically the fuel in the tank had heated to a point where the tank was pressurized.

I started to pay attention to tank pressure when I first took the cap off. And started to add fuel slowly at first to allow the new colder fuel from the underground tanks to cool off what was in the truck.

I have fore and aft skid plates and think they limit airflow some

Always stop fueling after the first click. Never top off.
The extra fuel and vapor are going straight to the charcoal canister.
