Anyone thinking about buying a diesel compression tester from HF, part #93644, they have changed the adapters for the glow plug, THEY DON'T WORK. See the difference in the two sets below.
The first two pic's are of the one I bought several years ago, same part #93644. IT DOES HAVE THE FORD ADAPTER THAT WORKS, #17 in the pic.
Bottom pic is the one for sale now, same part #93644, THIS ONE WILL NOT WORK, adapter will NOT fit.
Still a good price at $25, if you need the guage, the Ford GP adapter can be reworked to fit by turning down the diameter on the end.
