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.

WOW! A clear case of cost/weight ratio, but the ounces per dollar is really
steep in fuel valves. I need 3 of these puppies for a 4 tank system.
The andair guys are over $500 each.
$380 vs $1500. I don't even care what the marine valves weigh.
Thanks for an enriching discussion.
