FG Wilson Generating Set Installation Manual page 19

Flexible piping should be used to connect to the
engine to avoid damage or leaks caused by engine
vibration.
The fuel delivery line should pick up fuel from a
point no lower than 50 mm (2") from the bottom of
tank at the high end, away from the drain plug.
10.5 Day Tank Capacity
The capacity of the day tank is based on the fuel
consumption and the expected number of hours of
operation that is requested between refills.
Particularly with standby generators, the availability
of fuel delivery service will determine the number of
operating hours that must be provided for. Don't
depend on quick service the very day your set
starts to operate. A power outage may hamper your
supplier's operation also.
In addition, the size of the day tank should be large
enough to keep fuel temperatures down, since some
engines return hot fuel used to cool the injectors.
