Hello Paul,

   Does anyone have a source for a reasonably priced duplex fuel valve
   like the one
   you sent a photo of? Aircraft Spruce has them at over $500.00.

   Check out the boat shops. They are heavier but they are very
   robust.

   Check out Andair.com here:

   They run around $300, depending on options.

   Thanks Brian.

   Looks like the best price is from JMSonline.net    current price is
   $126.51

   As for disabling the "both" selection-- I think that a mechanical lockout
   of the
   both selection is possible, no?  I imagine it'd be quite easy to add
  blocks
   or
   selector stops that would prevent the valve from swinging through it's 360
   degrees.  It's swing would be more like 180 degrees instead, is my
  thinking
   flawed here?

   Good idea.

   Thanks again to all.

  This looks like a nice product but not many people will see it.
  Brian to prevent this happening go to tinyurl.com
  and plug in the long url and out will come a short version.
  cut and paste that into your message.

  Alternative maybe to the marine/aviation 6-port

  I like the price point, but I'm cautious about the electric operation, and no
  real product detail in the description. In order to feel comfortable, there
  would have to be some form of independent indication of actual valve position.
  In other words, when I select a tank with the switch, I want to know that the
  valve changed position right away, not when the engine stops from fuel
  starvation.
  With a manual valve like the Groco, there is no ambiguity.

The Pollack six port valve that we are referring to is used extensively in Aux tank installation to injected 4x4's and vegetable oil burning instalations. It has switched contacts to indicate which port is open.
Circuit attached.
