ATV Fuel Cap Vent Tube

[KennK]

My newly purchased used Honda Rincon ATV has a vent tube that comes out of fuel cap and goes into the dashboard area.

My JD tractor doesn't have such a tube. Why does my ATV have one?

What does the tube "do" in the dashboard area? What happens in there???

I've searched and searched on the web and am kind of surprised that I can't find the answer out there.

When you take it in a deep waterhole up to the seat,keeps the tank from getting water in it.If its deeper than that youd be floating up side down by thenTractor doesnt have one...welll i think most of us dont run our tractors like that:
From an avid atver with 4 machines and do all my own repairs my advice is keep it out of deep water ..hard on stuff

The tube is also to keep gas from splashing on you while riding over bumps or up hills. A tractor is normally not going to be driven as harshly as a 4-wheeler. Plus the fuel tank isn't between your legs on a tractor. lol
The vent is necessary to maintain atmospheric pressure in the tank.

Thanks for the replies!

What is on the end of the tube opposite the fuel cap - where its stuck into the dash?

Is it just stuck into a dead-end hole? Or is there something else to that hole in the dash?

The tube is probably just open on the end.
The hole in the dash is just to hold the vent tube in place.

Yep - mostly the tube just "ends" , the "hole" in the dash is just a sort of holder for the tube and to keep it facing downward and away from the ride. You can just give it an easy pull and it will slid out and you can look at it then slide it right back in.
