Tank is leaking with a small crack in it. My plan: Drain gas. Rinse the tank with water. Rinse the tank with acetone. Let sit for an hour. Clean outside of crack with a degreaser and then some thinner. Weld it shut with plastic and a soldering iron. Plastic epoxy over the weld. My question is does anyone know the plastic make up of most fuel tanks so I can choose a proper epoxy? ---

The only real way of fixing a leak is repairing internally. Have you priced out a used(wrecking aka junkyard) fuel tank from a similar vintage CRV? ---

$400 for one… I was thinking about a sealer from the inside, but so many of these seem to be incompatible with plastic tanks. I have used them on motorcycle steel tanks and they work well.
