Bob,
Yes, bike breakers here are the same thing as your salvage yards. The tap came from a recently broken (dismantled for spares) bike, but I don't know which model.
There are quite a few variants of vacuum tap, on the one I got the lever goes in a 180' arc from horizontal rear for off, through straight down for on, to horizontal forward for reserve.
Here's the link to the thread I got the idea from:Slinky's fuel tap mod'
If you look at the picture of my bike you can see the vacuum connection from the inlet stub, the fuel line is the larger rear facing hose.
