    EFI fuel tank vent question?

    hope I can explain this clearly:
    when there is fuel in the tank and the tank sits in the garage or even in the sun for a few, if you were to remove the fuel cap, you can hear some pressure escape when doing so.
    Even when the ski was stored over the off season, as the temperature changed in the garage, you could remove the fuel cap and hear the same...
    since the beginning of this season, it has not done this at all, either way while sitting indoors or out in the sun with fuel in the tank, there is NO pressure build up in the tank...

    the ski itself runs fine, just thought it was weird that all of a sudden it stopped...

    does this mean the white check valve in the vent line is stuck open? or went bad? Thanks...Andy...

    Hey PR def check the valve. The GPR,s only have one valve to let air in. Most other's have two valves to let air in and out. I believe the cracking PSI is 3-5 psi.

    Also remember that in the republic of NJ you have summer gas from June 1st. Summer gas has a lower RVP then Winter gas. I also notice a difference in venting during the summer. In the summer I have zero tank farts. In the winter its like a toilet after a Chinese buffet.

    hey Steve, I have not seen the tank or hose collapse, just no vapor or fume build-up as it would during the winter...

    seriously that is a great point that you bring up!
    That`s exactly what Im experiencing...lol...

    but I`m pretty sure it would gas in the heat... maybe some new formula`s or ethanol has something to do with it...

    Thanks for the tid bit!
