HELP.....GAS TANK REPAIR...HELP
I have a Crestliner 1754 with a built in 22 gal fuel tank.
The tank has a small crack in the corner near the location where throttle cables go thru hole leading back to the engine.
This was done by previous owner when he tried to fish wires.(at least that’s what I was told)
I can access this area after removing the control box and pushing cables out of the way. That leaves me with a very limited area to work on crack but manageable.
I tried to heat(melt) crack with soldering iron and then using zip ties to fill area of crack. Then a small amount of JB weld marine grade on top of that. (It lasted a while).
Wondering if I used the plastic from old gas tank and melted it over crack it would be better????
Sorry for the terribly long post.
Any suggestions would be appreciated.

Agree might be more trouble than it's worth and then you would never have to think about it again.

I’d replace tank. Gas fumes in a boat are to dangerous to try to save a few bucks on. And I have seen nothing in the plastic welding world that is designed for gasoline or diesel fuel.

You can get polyurethane sticks to melt into poly, but,,,it takes heat as the sticks are used on repairing kayaks that develope cracks and holes from whitewater kayaking. But you have to melt the poly or plastic your repairing as you melt the sticks to fill the crack. In your case this being a gas tank, get a new one.

Worked in a chemical environment for years. Flammable vapors are the culprit of most accidents. Please replace your tank and be safe. Seen boats burn to the ground with just a simple fuel line leak.

Can’t remove tank.
It is completely covered by rear deck.
I think I can fix the very small hole without doing that, but thanks.
