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.
