    Fuel leaking

    SN#1B540491 250proxs Opti. I noticed that I have a very small amount of fuel leaking out of the hose that vents VST where it comes out through the adapter plate. I'm assuming that the needle is worn or has trash in it not letting it seal off and getting to much fuel in VST. Anything else I need to look at for this problem?

    I noticed that if I pump up bulb I don't get the leak. Only when running.

    It's a very small amount coming out while running. Not really dripping or pouring out but more of a mist.

    I wouldn’t run it until it is resolved. Fuel dripping, leaking or misting is not good.

    Don't plan on running it until fixed. I've just never seen one leaking because of inlet valve while running but won't leak pumping bulb. Hoping to get some ideas from the optimax gurus.

    Worn needle, worn divot in float where it contacts needle, hair/plastic/debris in passage between filter/needle are the most common causes.
