Title: Leak Down Testing Tools and Accessories Question
Post by: tinkerswithengines on February 16, 2014, 06:21:20 pm

I was planning on buying a Mityvac 8500 Silverline vacuum and pressure testing tool kit for performing leak down and vacuum testing on 2 cycle engines but I noticed it dosen't come with a 14mm spark plug adaptor to connect the air hose to the pump/gauge. Can I buy or make such an adaptor?
Any suggestions would be helpful. Thanks!

Dave

Husqvarna also makes one not a dual purpose like the one gunrac pointed you to. It is HVA pat number
503 84 40-02

The mityvac works very well, I use one however if you want to do it on the cheap buy a used blood pressure cuff at a garage sale for $5, get rid of the cuff and you have the pump, gauge and hoses right in your hand.

All you have to do is convert mmhg to psi or kPa.
