Why is it suggested to refuel a dumper at the end of the day?

Refueling a dumper at the end of the day is suggested mainly to minimize condensation build-up in the fuel system. When a fuel tank is partially filled, there is a greater amount of air in the tank. This air can lead to temperature fluctuations, causing condensation to form inside the tank. Water from this condensation can mix with the fuel, potentially leading to fuel quality issues and damaging the engine or fuel system components.

Filling the tank completely reduces the air space, thus limiting the potential for condensation formation. This practice keeps the fuel system in better condition and helps ensure optimal performance, which is particularly important for heavy machinery like dumpers that rely on consistent and reliable fuel quality for operation.
