What this video covers

A DIY fuel processing system designed for the 90-liter LPG cylinder on the trawler Brupeg removes water and contaminants from diesel and waste vegetable oil.3:23 The system uses a two-stage vacuum pump to dehydrate fuel at room temperature, pulling it through a 10-micron bag filter into the cylinder.3:34 Once the fuel is dry, positive pressure from an air compressor forces it through a 1-micron bag filter into the boat's fuel tanks.6:01 This setup allows the vessel to run on both diesel and waste cooking oil, which offers higher lubricity and lower costs than standard low-sulfur diesel.2:12 To prevent fuel contamination, the crew installs water drains at the bottom of the tanks and uses ball valves on sight glasses to meet survey requirements.23:30 The owner also repairs a leaking tank bung by cleaning the threads with brake cleaner and wire brushing before applying fresh thread sealant.11:24 Proper tank maintenance, including keeping tanks full to minimize condensation, remains essential for preventing diesel bug growth.
