My kids quad bike's plastic petrol tank has a crack on its neck . Is there a
glue that is petrol resistant to fix this ? My other option is to use a
soldering iron to melt it back together . Would this ignite the fumes in the
tank causing an explosion or fire ?
A glue which will glue plastic and then be petrol resistant? Hard to do,
depends on the plastic, but eg some structural acrylics or hot melt FEP
adhesives might work.
Tell me more about the plastic - does it float? what happens if you burn
a small piece, melt? smoke?, smell?
Where are you?
Use of a soldering iron should be fairly safe, it should not ignite
petrol or petrol vapour. Whether it will mend the crack is another
question, plastic welding can be tricky. Take your time, if possible
practice on some similar plastic. It's one of those skills you can only
really learn by practice.

Peter is right that a repair might be possible given time and practice, but
you then have to ask yourself if you really want your child riding around on
a machine that may erupt into flames if you got it wrong?

Thanks Peter , I'm in darlington , England . I decided to weld (solder) the
plastic and it's worked a treat , it's a fantastic way of repairing cracks or
splits in plastic . The soldering iron doesn't get hot enough to ignite the fuel
( I practiced by dipping the hot iron directly into a very small amount of
petrol ) . The weld lokks and feels solid and we took the quad for a test run
and there is no leaks , a great quick fix that means you don't have to mess
around taking the tank off . Happy days !
