Would an electric tire inflator pump be a good or bad choice for testing for vacuum leaks? I already modified the fitting to connect to a vacuum hose and it pumps a nice amount of smoke through the rig I made, but I just don't want to blow out any of my vacuum system or anything. I don't know how powerful this thing is or if I should worry about that. Anyone had any experience? I also have a hand pump that I used, but I'm not seeing any smoke come out anywhere.
