PETROL FUEL SYSTEM LAND ROVER 110 TWIN TANK INSTALLATION Description The fuel system includes two fuel tanks, one at t h e rear of the vehicle and an additional fifteen gallon litres) capacity tank on the right-hand side of the vehicle. Both tanks contain an electrically operated submerged fuel pump in addition to a fuel level indicator unit in each tank. An ignition controlled on the control panel enables the driver to select the tank to be used. The switch also energises the fuel level on the single indicator dial. When t h e ignition is switched ‘on’ the pump in the selected tank will draw fuel into the carburetter float chamber via a paper element type filter and a vapour separator. To prevent fuel vapourisation and air locks a return system is incorporated in the fuel pipe layout to pass back vapour vapour separator to the tank in through a restrictor and a solenoid operated valve. The valve, which is by the tank selection switch, closes the port to the tank not i n use and simultaneously opens the port to sclccted tank. The restrictor is necessary to prevent fuel by-passing the carburetter and flowing back to the selected tank t h e rear and side tanks to prevent the possibility of back-flow of fuel along the supply lines to fuel tanks. A. Fuel tankswitch LAND ROVER 110 REAK TANK AND 90 SIDE TANK Description Fuel drawn by the electrically operated in-tank pump, the right-hand front footwell attached to a chassis outrigger from fuel enters a vapour separator located on the left-hand side of the bulkhead in engine compartment. Fuel finally carburetter float chamber from the port at the base of the vapour separator. The vapour separator comprises part of the spill return system and its purpose is to the carburetter. Vapour and excess fuel flows back into fitted return port on the vapour separator. The restrictor is designed to assist in maintaining a constant fuel level in t h e vapour separator bowl and to prevent fuel flowing back to the tank at the same rate as the delivery. FUEL FILTER C.
