Matt, my friend (also lives in SM) has a home made drip tube. No help on the compression tester - you're better off with a new one on that item I suppose Ebay for many things is hit or miss.

Let me know if you want to contact the man for the drip timing tube by PM. I don't envision any midnight auto work, I did that in my youth like changing a clutch in a driveway using cinder blocks for jackstands and a 30 degree North wind to keep cool!
