JB weld is a great product for many application that do not involve fuels or constant heat cycles like a radiator brass or plastic tanks. I've seen that stuff slathered on everything imaginable. At best it will buy a little time and slow down a severe problem in an emergency. It has never been what I would consider a permanent correct repair material.

Yeah, JB weld is out for the gas tank. I've been looking online for a decent used one. I'm in Canada, so probably going to have to put the word out and wait.
 
All of the JD X series mowers had fuel tank issues eventually. They were just a poor design as if the engineers added the tank after the chassis drawings were approved. Oops!

Mine looks like a rat was gnawing on the corner. there isn't anything close by to rub/cut into it. weird.

And that could be the culprit. You should see the mess the mice made of the wiring. Too bad it was left outside for a couple of years before they decided to sell it.

HDPE plastic is highly chemical resistance. Nearly nothing will stick (bond) to it, I did find one product that claimed it bonded to it but the time it was over $300 for an ounce. The repair method is plastic welding. And badly deteriorated tanks it is best just to replace them.

I was just reading about West Systems G/Flex epoxy. Highly impervious to gasoline, and one of the best for adhering to HDPE - if the prep is done right. I bought some for the cracked JD 'Zenoy' hoods. Going to give this a go before forking out for a new gas tank. I'll let you know if it bonds.

Yes I have mice to chew on hydraulic oil reserve tanks. I even had a new bottle of hydraulic oil that a mouse chewed a hole into it that I left sitting out on the bench. What a mess.

I think part of the problem is that manufactures are combining modified soybean oils and regular petroleum oils to make some plastics and mice loves soybeans.

Here is one note from the user manual.
HDPE (high-density polyethylene) and LDPE (low-density polyethylene) must be flame treated for good adhesion.

So it is the cleaning and the removal of the oxidation layers. And the blue tip of the flame must touch the surface of the plastic being bonded. I definitely recommend practicing on scraps before attempting this.

So no gasoline or fumes can be present or it is a flame out.

Hi StarTech,

The same thing happens to modern wiring insulation. The rodents think it is a food source because it is made from cooking oil production waste.
Very little modern vehicle or equipment wiring insulation is made from petroleum products these days

Rubbing alcohol really works to get the petrol residue out of the plastic. I've steam cleaned it inside and out, and it's still giving off vapor big time. Going to let it sit a few days, and air it out. Possibly stream clean it again. I won't use the alcohol until right before I'm ready to patch. Thank you for the tip on flaming the plastic. I see it's also recommended before repairing the zenoy (soybean) hoods. Yes, definitely good to practice before the repair. A lot of recycle products are HDPE, so no shortage of practice pieces. I have a few scrap shards of the hood material too, but I don't know if it reacts the same way as the tank would.
