BRACKET (L.H.) 7F5714 - Caterpillar

On power units, where the fuel tank is not installed at the factory, remove the corks from the fuel transfer pump and the fuel filter housing. Connect a fuel supply line from the fuel transfer pump to the fuel tank, and a fuel return line from the fuel filter housing to the fuel tank. The fuel transfer pump will lift fuel the height of 12 feet (3.7 meters) through no more than 50 feet (15.24 meters) of pipe. It is essential that there be no air leaks in the suction system. Even a small leak will destroy the suction lift of the transfer pump. To prevent leaks caused by engine vibrations, flexible fuel lines (1) and (2) are recommended for use between the engine and the diesel fuel tank lines. The flexible lines are available from your Caterpillar dealer.
CONNECTIONS FOR FLEXIBLE FUEL LINES
1-Fuel return line. 2-Fuel supply line.
Never connect line (1) to the fuel supply line (2) nor directly to the fuel transfer pump as this may cause the system to become air bound. If a pipe plug is installed in place of the return line or if the return tube is too small, fuel pressure can burst the filter housing.
