Re: 1996 GMC K3500 fire engine, gas, 5.7 L engine....

Re: 1996 GMC K3500 fire engine, gas, 5.7 L engine. This truck has dual fuel tanks. How does one switch from one tank to the other? If this is automatic, how does the switching work? This truck, when out of fuel on one tank, does not switch to the other, and we cannot find a manual switch anywhere on the truck.
