fuel tank selector switch

[blown_superjet]

I have dual 10gal tanks that need a high flow capacity tank seletor switch. (1/2") I'm running -10 line to a new blower motor and the original manual selector switch is maybe 5/16 at best. I would like in electric unit that I can switch from the dash. Any one have any suggestions?????

Imco superflow valve will get what you need. Outside of that, Dana Marine Products makes a new valve, but I'm not sure of the price or availability.
