[TR] Facet Pump

[Alex]

A few quick questions on the facet fuel pumps. I am putting one on my 59 TR3A
since I have now gone through my second mechanical one.
  1.. Behind the mechanical (tank to pump) or in front (pump to carbs)? I
prefer behind because of the rubber hose availability, any pros and cons?
  2.. Wiring connections?
  3.. Any need to modify the mechanical or will the facet push/pull through
it.
  4.. Does it require a pressure regulator?
Thanks
