The 5-gallon spill box screws into the existing fuel fill port of the base tank. It captures and
contains fuel if over fueling or spilling occurs during the fill process.

Tank risers are required in some municipalities to help avoid potential base tank corrosion
caused by mounting on rough surfaces.
A powder coat painted, steel fuel fill drop tube is required in some municipalities to prevent
sparking due to static electricity buildup, which can be caused by the fuel dropping into the
tank from the fill area. Using a drop tube also results in submerged filling, which increases
the fuel delivery flow rate and reduces vapors, foam and potential tank evaporation.

Some municipalities require the use of stainless steel fuel lines instead of the standard hoses
Stainless Steel Fuel Lines provided with the diesel generator products. These stainless steel lines are fire resistant for
additional safety.
E-stop allows for immediate fuel shutoff and generator shutdown in the event of an
emergency.

The spill box drainback kit allows fuel that was captured in the 5-gallon spill box to be drained
directly back into the fuel tank to avoid vapors.
