Hi guys this is a new leak down tester that I put together. I was walking around tractor supply and just seen the items so I picked them up only a couple bucks here and there. In the picture I circled where I am going to add a quick release valve so that I can use different size coupling ends which I'll already have made up to fit different size intake manifolds. I haven't seen this done but I thought it was a great idea now where the blue circles are I will be adding a cheap uni type air filter cut up and stuffed in the ends of the hoses so I don't blow debree into the engine the way I am I don't want even a grain of sand or anything that could have gotten in the hoses into the cylinder. Just hoping it's a good idea lemme hear some inputs. Also I have put hose clamps on all the connections just FYI. Just took the picture as a draft.
