Repair rear shock air lines

I've got a pinhole (from rubbing on the inner fender) in one of my rear shock airlines (2001 Aurora). I've been searching for something to patch it, as the dealer wants $140 for a new pair of lines. I have seen plenty of suggestions in the archives for aftermarket air shocks, reusing stock lines, or using aftermarket lines on aftermarket shocks, but I haven't been able to find anything that would let me cut and splice my existing damaged line to the stock shock.

It appears that the airline OD is about 1/8" or so, and the ID seems too small to use a barbed coupler.

Thanks!

Welcome to AF. They make 1/8 compression union fittings also.
