External fuel tank:
Generally suitable for open-frame diesel generator sets. Advantages: practical, suitable for various places, and can be used when installed with diesel. Disadvantages: unsightly.
Base oil tank:
Advantages: There is a large amount of oil, and the whole machine belongs to one.
Disadvantages: Because it is an integral fuel tank, diesel fuel is deposited in the base fuel tank for a long time, and impurities will be generated after a long time. If it is not cleaned for a long time, it will cause damage to the oil circuit of the diesel generator set. So relatively speaking, the external fuel tank has a slight advantage over the base fuel tank.
