• Do not allow the module to draw fuel below 75% of the fuel tank
capacity. This is required by NFPA standards to ensure that there is
fuel remaining to move the apparatus.
• Set the return line 1/2 inch (13 mm) below the supply line.
• Non-metal lines must withstand operating at 212 °F (100 °C).
• Route the lines as straight and as short as possible.
• Make sure that the line doesn't kink.
Choosing the Fuel Tank
• The fuel tank must vent at any operating angle.
• The tank cannot be made with or contain a high level of zinc.
• The tank must allow sludge to drain.
• The fuel intake cannot be lower than 78 inches (2 m) from engine fuel
