Snap On Tools Diesel compression adapter set #MT3509 This set has only been used a couple of times and is no longer needed due to health problems.
Those of you who've rented or borrowed my diesel compression testing setup know that this is the set of GP adapters I use.
I've been trying to put together a second testing setup. I have had another low-profile 90° adapter fabricated, I have a second gauge setup, but no GP adapters. I have been looking for exactly this set for months, but my Gawd, somebody sure wants it more than I!
I think I paid under $50 for the 3509 set I have now.
