Man I HATE plastic gas tanks! I got this old free boat and it has a '70's Mercury 70hp engine on it. I've posted a few times with various questions on fixing it. Maybe this ought to be in another forum since it's more tank related than Mercury related but I wasn't sure so sorry if so.
Anyway, the boat had some old plastic tanks in it. Seemed like the thing to do to replace the tank so I bought a new Moeller 6gal tank. This thing baloons up in the sun, yesterday I found even with the floats in the carbs sealed it still weeps out of the overflow when the sun hits the tank. What to do?
I have a machine shop. I'm tempted to take the stupid cap off and remove the vent valve, which is only a vacuum breaker, and make my own vent. I do see caps for sale that supposedly have vents in them but maybe these are the same? Not sure.
