    Fuel Vent Location

    Does anyone know where I could find the vent for the fuel tanks on a 2013 Z520? I’m thinking that I may have a clogged line or vent screen.

    Ok, so I figured out that the fuel tanks vent thru the cap from a rectangular fitting at the top of the filler hose. My question now is, should I be able to blow air into that rectangular fitting? I tried to do so and am getting resistance so I either have a clog or their is a check valve of some sort?

    there is a check valve sometimes, seems to slow venting down and causes the pump to keep clicking off if filling too fast.

    So is there anything for me to check to make sure that my fuels tanks are venting correctly?

    Lightly pressurize tank.
    If venting properly, then, if epa compliant, should vent anything above 5 psi.
