New question-Plastic welding?

[ericandrews331@msn.com]

Okay folks has anyone ever had any success with patching a crack in a plastic FUEL tank. Ive tried JB weld works for a little while sometimes days sometimes weeks but it always starts again

I would replace the tank. That stuff is hard to get anything to stick to - and whatever you use has to be able to stand up to constant contact with the gasoline.

yeah I have tried but this is actually an early Stihl Auger that works and runs like a scalded dog but other then a gas cap and an auger extension no parts are readily available for. Since most of the tanks I have seen on the club cars are plastic I thought somebody may have come up with a method

friend of mine had this problem. cracked out all the way around the cap. he tried several times different ways. worked for a day or 2. he finally got a new used tank

I have already used a soldering gun with a flat tip and melted the crack back together.

I had a 4 wheeler once with a spot worn thru the tank. It leaked all the time. I was able to fix mine and it never leaked again.

I have a good airless plastic welder. It comes with lots of different types of plastic filler rods for things such as the plastic bumper covers, dash covers and the such. In the bunch is something they call universal rod as well. It's a kit that is sold by Snap On tools as well as other places. It isn't cheap coming in at $200 plus but I've found was a good investment.

With the right tool a plastic tank can be repaired successfully.

Use zip ties and melt then in with the soldering iron

Tank should be HDPE (High Density Polyethylene) if that helps.
