The Superbus shall be refueled prior to the end of the shift regardless of the miles driven.
When filling the fuel tanks on a Superbus, stop when the nozzle clicks off. Do not attempt to top off the tank, as fuel expansion will cause an overflow and spill fuel.
When fueling, the pump hose shall be attended at all times. Due to the large size of the fuel tank opening, it is very easy for the nozzle to fall out of the tank and cause a fuel spill. If fuel is spilled around the fuel pumps or overflows when the vehicle is parked, grease sweep or some similar absorbent shall be applied to soak up the spill.
