What this video covers
The crew of a cruising sailboat attempts to resolve recurring engine failure caused by suspected diesel bug and debris in the fuel tank. While at anchor, they source replacement brass fittings and diesel treatment solution from a local town, though they struggle to find parts matching the specific thread size of the tank's existing shut-off valve.0:55 To clean the system, they drain approximately 50 litres of diesel into storage bags and use a 12-volt oil extraction pump to remove sludge from the bottom of the tank.9:03 They replace the fuel lines, install a new feed fitting, and filter the original fuel through a fine-mesh gauze before returning it to the tank.9:48 The crew also replaces the primary and secondary fuel filters.8:19 After reassembling the fuel system and verifying there are no leaks, they successfully restart the engine.12:25 The crew notes that while removing and pressure-washing the tank would be the ideal decontamination method, the process is impractical while at anchor due to the requirement of removing the engine.11:54
