1/8 NPT on the block side. 1/8 compression on the other. Should be available at the big box lumberyard, OR your local auto parts store. Take a close look at the compression side- some GM used a slightly different style of compression fitting and they are NOT interchangeable. If the ferrule on your existing line is cone shaped it's the one GM used. If it's a round looking ball, then it's a commercial fitting.

The cone shaped ferrule will not rotate when you tighten the fitting, cutting into the plastic line. Also the cone fittings have course threads and need a special compatible nut.
Some fittings have a captive ferrule that is locked into the nut and these also will not cut the line. Hope this helps. Lou.
