When operating the BPU in a humid environment, what is necessary to prevent contamination build within the fuel tank?

To maintain the integrity of the fuel tank in a humid environment, refueling more often is essential as it helps to minimize the chances of water accumulation and contamination. In humid conditions, moisture can enter the fuel tank and cause issues such as microbial growth, sediment formation, or water accumulation at the bottom of the tank. By refueling more frequently, there is a reduced likelihood for contaminants and water to settle in the fuel tank, as fresh fuel can help displace any water that may be present and keep the system clearer of debris and biological growth.

While moving the tank indoors or rerouting fuel lines may seem like plausible options for preventing contamination, they do not directly address the underlying issue associated with humidity and its impact on fuel quality. Draining water hourly may be impractical and may not significantly mitigate the long-term effects of moisture intrusion, particularly in a humid environment. Frequent refueling acts as a proactive measure to ensure fuel quality and prevent contamination.
