    Anyone recommend what to use for a hole measuring .650 inch or 16.6mm?

    How thick is the plastic? Maybe a husky petcock that mounts with screws.

    Thanks guys, I have one on order that may work. Plastic is probably too thin to screw one on.

    Years ago or decades ago I took a hex bolt and drilled and tapped a 1/8" npt thread. I installed it in that hole with two o rings. The bolt on the inside. I used a lawn mower threaded gas tank shut off. It worked. Probably 25 years ago.

    hit up your local ski-doo dealer for the tank grommet and then the local lawn mower shop for a push (barb) style petcock.

    Don't forget if there is no fuel filter screen on the valve better put one inline.

    Measure the hole in the gas tank. It's either 5/8" or 3/4" that's the size hex head bolt you need.

    You drill a hole down the center of the bolt. You tap the outer end 1/8" npt. Install a rubber o ring under the head of the bolt using a 3' piece of TIG welding wire you guide the bolt to the hole inside the tank through the filler opening. Install another o ring, flatwasher, nut. Using a long extension on a wratchet tighten the outer nut. Do not turn the bolt inside do the o ring doesn't get distorted. Install the male 1/8"npt valve with the hose barb.

    when i used to use that style i had good luck safety wiring the ends of the rubber. i have abandoned those and run the single shock kicker on them now tho...the bullhorn kicker is not a fav.

    the bike is starting to really pop! nice work
