Leak tester
This tester is a great tool for any mechanic that is serious about performance finding leaks is simple and effective especially in snowmobiles we have found that the exhaust is always suspect to leaks and should always be addressed. It does not fit everything out there but gives you enough to test 90+% of what is out there. Just as a side note dont lend it to friends I am still looking for the one that I worked for and someone borrowed!! A+++ product and would strongly recommend it. I'm saving to buy another one.:)

I bought this leak down tester in '98 for my TZ 250. I've been using it ever since. It works and lasts. When testing a 2 stroke engine for air leaks I want the engine to hold 7 psi. Ed Sorbo EDventure Racing
