@NMKawierider and everyone.

I want to delete the evap canister it catches all the mud, one screw is stripped and it is rattling.

Ok so from the top of the tank there is a line going to a check valve (passive no wires), then to the evap canister, then to another check valve that is wired, and then finally to the throttle body.

I will keep only the first check valve and route the line somewhere high.

What's the purpose of the first check valve? Let air in? Let air out? In theory it should do both. Can-ams have two check valves one blue and one red, one lets air in and the other lets air escape if the tank is under pressure (e.g. sunny day).
I tried blowing into the valve with my mouth (force air into the tank), i couldn't. Tomorrow i will try with the air compressor from both sides.
After a ride when i open the gas cap there's a woosh, air is rushing out, so there is pressure inside the tank.

Do i keep the valve, or not? Do i put a filter on the end of the line? what kind of filter?
What about the second check valve, the one that is wired, what is its purpose? Do i remove it altogether or do i keep it plugged in?

Thanks.

On the older ones like mine, it has a check valve built into the tank that only lets air in as the pump takes fuel out. When heated or shaken pressure builds but it's only a couple of Ozs although from the feel it acts like much more. I do not know how they vent the new ones and not sure on the evap can and how it works but...its is supposed to take gas fumes and through an EGR valve, it pulled them in from being collected in the canister. That EGR valve is electric and on the intake. I have to assume that new first tank check valve must be pressure sensitive so that pressure will send the fumes/vapor to the can. I would not put compressed air on it as it could damage it...but maybe it's not the type you want anyway. On mine the builtin check stuck open and let gas run up the vent and into the frame where they stuck the end. I put an inline check valve and fuel filter on it and put a loop high on the frame. I have a how-to in the how-to section on that.
I would leave the wires on the other valve(s) and just cap them well because anything else would likely cause an error code to come up on the dash.

Ok, so i was blowing in the wrong hose...
After i removed the rear fender, i found the correct hose. The valve is a two way valve that has some resistance but i can blow air in and out. When blowing air out there is a little more resistance, i guess in order to block gas from leaking out in case of a roll over.
Deleted the evap junk, capped the throttle body and the solenoid valve, and i put a small gas filter on the end of the line resting below the seat.
Everything as it should be now.
