If its plastic it cam be plastic welded
I have on several occasions had to weld up fuel tanks and handles on saws as well as other items
If you get a good sizes electric soldering iron nice n hot you can then run the tip along the crack to a depth not more the 1/2 to 3/4s the thickness the parent material
the tip of iron will leave a furrow as would a plough
you can then used the tip to push or spread this material back into the trench and smooth it over nice
I will do this in short lengths so as to still hot material in the bottom of the weld that the top can stick better to
you can also use a filler rod of the same type of plastic that you are welding up getting a better result
this trick has helped me out several times now with very pleasing results saving me a few quid
Its worth thinking about
for helpful hints Google it and you'll get video on YouTube :O)
