Gas tank pressure fueling up!! 🤬

[KCKracker]

I have a 20 ft trophy with an outboard and when I go to fuel up I can barely put gas in slowly otherwise my tank pressurizes and blows gas back out to put in $10 literally took me like 15 minutes. My tank has a 5/8 hose coming off of it but the problem is the vent going outside the boat has tiny little holes in it and I have been unable to find something with much bigger vent holes so the 5/8 hose is pointless what do I do should I tee off the line and add multiple vents or what

Check your tank vent line. The vent itself is fine from your description
also check the fill line

I would say the vent screen or hose is plugged.

The vent screens also plug up, although you would not expect them to. Maybe it is time for a new vent.

Or a sag in the vent line and the vent line is now full of fuel.
