Got a ghost in my shop.
Walk into shop one day smell old gas...didnt think much about it, got busy working around the house, wife found gas coming out of the drain hole on my Taylor SJ.
Do an inspection, appears to be one of the saddle tanks leaking, was eating the paint off the floor. So it was a pretty obvious trail. Tank was not completely full but guessing 3/4 full. So i have an idea to were leak should be, no fuel line around "wet" area, guessing tank was rubbing on floor and finally created a thin spot or something.
Pissed off, yank interior and tank. Filled the tank with water, was advised water is thicker than gas....no leak. Pressurized the tank with air, spray bottle soapy water....nothing.
Frustrated a little more....filled tank about 3/4 full with gas....let it set for 3 days...nothing...filled the rest of the way to the top. Let it set for a few hours...nothing...drained tank and got to scratching my head.
The tank has a rear pickup (at the transom) and sending unit, fill neck is 1/3 from front of tank, front of the tank is the vent, boat was level to slightly nose up.
The only "hose" around the area is the vent hose. About leaking spot is where the vent hose is connected to a check valve to prevent water going in, then hose to top side.
Could the vent hose created some kind of suction or vacuum? Maybe check valve is broke?
The battery is disconnected for winter time, so kids could not of done anything. Fuel pump is electric. I dont want to replace the tank...PITA...measure...order...hope it works.
I am not completely sold on putting the tank in and running it. Thought about smearing some JB Weld in the areas that look iffy and run it. Planning on taking it somewhere to get it pressure tested. Any ideas?
Also boat has been sitting for months, unmoved, heated shop, thermostat on 45 unless i am out there then i turn it up. Leak occurred a few weeks ago, heater has not been running.
