lol I thought that was a bit strange! Yeah, evap leaks can be tricky! "Technically" you can't use a standard smoke machine to check for leaks due to the possibility of igniting the gas, but the alternative costs over $1000! What I plan on doing if I have a leak is to use my homemade smoke machine and hook it up to some sort of holding tank for the smoke, then disconnect the smoke generator portion and blow the smoke into the system under pressure. Now, even this is risky since you'll be putting a slight pressure and air into a gas tank so any sparks will cause a big boom, but as long as you're not stupid and smoke around it, you shouldn't have any issues. It's a lot better than the alternative of having a shop do it! Just my thoughts on the matter.
