Shopping was quick and easy. Part price was OK, but when shipping was added they were about the same price as others with free shipping. After receiving and checking the vacuum switch, I found the casting ridges quite pronounced where the hose is supposed to seal, also the switch looks like it was not threaded in squarely to the fitting. Don't know if it leaks, I have not installed it yet. I did smooth out the hose connections with crocus cloth.
