That's a pretty good find, Guruerror. I'm impressed. But the product description gives little information and the one reviewer complained it only fits the type of gas cap with a "narrow top." What's the size of narrow? </rhetorical question off>

I am thinking of finding a tightly wound stiff spring with the proper I.D. and pushing the two ends into it, Chinese Finger Trap style. Something in this set should work:

Next, I'll secure the joint with some Adhesive Lined Heat Shrink Tubing like this stuff:

I'm hoping the spring will provide some stability to the broken joint and the tubing should keep both pieces held together. It just might work.
