facet pump mounting BJ-8

["David Z" <davzu29@cox.net>]

I purchased a facet pump as a temporary replacement in case my current one
gives up at an inopourtune time.  Does anyone have a suggestion as to
how/where the pump should be mounted under the car?  Does it matter as long as
I follow the pump instructions? I recall some people writting in suggesting
they've wired one in with a switch to quickly turn off the old pump and turn
on the new one, but what's the primo location for the pump?
TIA
