Gas tank crack repair

What is good to use to repair a crack on a plastic gas chainsaw tank?

Use a soldering iron. Get it real hot and melt the plastic back together. I haven't done it but I have a buddy that does it on tanks and covers. They turn out pretty good.

Not a long term solution.

I've had pretty good luck with the two-part epoxy stuff. The kind where you mix the two ingredients as it gets injected into the problem area.

Just be sure to properly prepare the area to be bonded.

He didn't say long term or permant he just said fix... The real way would be to buy a new one..

Try SealAll. Dries clear, stays flexible. Does a real nice job.

Actually using a soldering iron works very well.

If you want to ship it to me, I'll be glad to permanently fix it with a soldering iron.

Anybody tried q-bond on a tank? Or bicarbonate of soda and superglue?
Used q-bond on a 288 top cover and spilled fuel on it, it's solid

i like to fix tanks with a paddle element on a soldering gun. i actually cut a v like groove at the crack to fill cause it seems to make it more tolerant of the beatings i give my saws. a newbie to plastic welding should start easy and skip the v like groove part though. clean in as good as possible with acetone before attempting this though as the tinyiest but of oil can make a real ugly mess.
