Have a Power King with big plastic tank. Noticed a bad spot in it today that looks like a hard edge scraped along tank and deposited the rubbed out plastic at one end of the scrape. At first thoght it was cracked, but doesn't appear to be thru the plastic. Anyone have special trick or compound one could put on this area to strengthen? Fiberglass? I have some JB Weld like stuff that says it resists gas and fuels? Seems I've heard from snowmobilers that there isn't much you can do with those tanks. Anyone?

JB Weld makes a Plastic weld epoxy that will work on your tank.

I think POR15 also has a tank repair kit that works on PVC tanks...

Repair's off. Foud with flipping my rear-end and the bulk of the case is on top now, the tank won't set down in tractor anymore. It had big indent for the rear. Can't move forward enough then to get axles to line up with their indents either. SO, will be looking for smaller probly metal tank to mount on same cross member which goes hight to mount seat/tail too. I'm at Portland this week, will have to look around and see what I can find. Was setting up some today and lots of GT parts were moving in. Going back for more tommorrow, but rules say NO BUyING till Wednesday when show actually opens!! Can look around if set-up, just can't buy, or not supposed to anyway. They can throw you out if you do. Have heard of that happening to couple vendors in past.

I've used the plastic weld on an old tank. It does well on a straight smooth surface but at a seam it didn't do so well.

The only method that I have tried, is the heat up the plastic a little and try forming and melting the two pieces back together if possible. I have a windshield washer tank in my old truck that cracked and leaked, and all I did was melt it together again. Never leaked again after that.

When you are trying to weld two pieces together the main object is to get both pieces liquidfied so they melt together, other than that it is a waste of time. Just like welding metal you need to two pieces liquidfied to have any luck.

I've used a soldering gun, welding plastic many times. I've also used a soldering iron

welding heavy plastic; i.e.: 1/2" thick.

 

Filler rod (plastic) is available but, I usually just use a piece (strip) of plastic that

I cut from a milk or juice bottle.

 

Slow with the soldering gun. :wave:
