INSTRUCTIONS:
This Selector Valve is intended for use
with the following: • Vehicles with one main and one auxiliary fuel tank. •
Vehicles without fuel return lines. • 12 Volt systems. • Ambient temperatures
between -40°F and +180°F. The selector valve must be located between the Fuel
Pump and the Fuel Tanks. Not for systems using intank fuel pumps or pumps
located between the tanks and valve. Note: Fuel injection systems and diesel
fuel systems commonly have intank pressure pumps. • Vacuum not to exceed 8
P.S.I. • Not for marine applications.
Selector valve should be installed as shown
above. Choose a protected location near the original fuel line and mount the
selector valve to a chassis rail (horizontal valve position preferred). Bolt
valve mounting bracket to chassis using external tooth lockwashers for good
ground. Route the auxiliary tank fuel line to the selector valve as shown. Cut
the original fuel line. Using properly tightened clamps and 5/16” fuel approved
flexible hose, connect the fuel lines to the selector valve as shown. Fuel line
routing should minimize bends and have largest possible radius for better flow.
A fuel filter must be installed between each fuel tank and the selector valve
input ports to prevent foreign matter from entering the valve and causing it to
malfunction. After assembly, check the system for leaks. Choose a position on
the dash to mount the toggle selector switch. Cut the original wire from the
sending unit to the fuel gauge and connect it to the selector switch as shown.
Connect a new wire from the switch to the auxiliary tank sending unit and
another new wire to the selector valve. The connection to the selector valve
should be made by placing the properly stripped wire between the two washers
and wrapping it twice in a clockwise direction around the terminal. The nut
should be securely tightened and a coating of grease applied to prevent
corrosion. Connect a new wire from the “accessory” power to the selector toggle
switch through a 1 amp fuse. Indicator plate should be used for proper
indication of tank selected. It is normal for “Constant Duty” solenoids to run
warm. FUEL FLOW: Valve de-energized: flow is from the main fuel tank thru the
valve to the fuel pump. Valve energized: flow is from the auxiliary tank thru
the valve to the fuel pump.
