1972 Fuel Transfer Valve - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have an Imperial gas valve installed under the driver's seat. The lever in the pax compartment looks similar to the assembly manual, but it seems to be a valve for two auxiliary tanks. It has one 3/8 inch hose coming from the main tank and two smaller 1/4 inch hoses going to each side of the vehicle. These have ferule type fittings. The lever has "Imperial" on it. It just freely turns and doesn't seem to "click" in any position. Is this a stock set up or something a previous owner installed?
