6-Port Motor Driven Valve

[jensenkennels]

I'm looking for an 6 port valve with 1/2" ID supply ports to use on my twin Ramcharger gas (now fuel) tanks. Something along the lines of a Pollack Item # 42-300 Light Truck 6-Port Motor Driven Valve (Light Truck 6-Port Motor Driven Valve on Pollak ), but with 1/2" ID hose for fuel supply ports instead of 3/8".
I like the design of the Pollack because with the flip of a button, it switches both lines simultaneously, avoiding cross-tank contamination. It even switches the fuel tank senders so your gauge reads whatever tank it's feeding off of.
Anyone have a source for such a valve?
