Default Plastic gas tank repair

I have an ATV made in China I didn't buy it!! It's a gift for my 7 year old Granddaughter. The nipple where the gas line is split someone cut the gas line off and slit the nipple . i want to epoxy it the epoxy I have says it will not work on polyethylene or polypropylene . What can I use on it ? What can you stick in hole in nipple that I can get out after what you tell me to use as not to get repair in hole and plug it ?

Ronny,
Can you get a bulkhead fitting into the tank and get the nut tightened up? If so this may be a longer term fix. More than likely if you can you will need to drill the hole oversize.
Just a idea.

I've done this in the past.

Take the gas cap off and cut a sliver of plastic off at the top of the threads. Then use this piece as a filler and weld it with a soldiering iron.

Because it is the same material it will bond quite nicely.

I went to u-tube and it showed welding with soldering iron. But i think welding the split nipple would be a bugger . But if I messed it up I like the valve stem Idea. I want to try epoxy but from what I've read not many over the counter that will work on this type plastic. New tank only 14 bucks but heck of job to get plastic housing off ATV to remove it.

I like the cutting sliver off filler neck your shure plastic is same to weld with. Theres no place like here for sugestions on doing things.

It has worke for me in the past. One of the challenges of welding plastic is that what you use for 'filler rod' must be the exact same chemical compound as what you're welding. Salvaging a sliver off the filler tube will ensure that it's the same material.

As has been suggested use a soldering iron for your heat source.

Check out this website. http://www.stealth316.com/2-dp8005.htm. Any bodyshop will have the correct glue for the plastic tank. The same type of plastic is used on many auto parts. 3M make the glue.
