What this video covers

Installing a new diesel fuel tank higher than the fuel pump does not cause operational issues, provided the system is bled of all air during installation.0:48 Fuel lines frequently route above and below the fuel pump, as seen in common installations where filters sit above the engine for accessibility.0:38 If the new tank sits above the fuel filter, a shut-off valve at the tank is mandatory to prevent fuel drainage during filter changes.1:57 Nigel Calder notes that ABYC standards require a shut-off valve in the fuel supply line regardless of tank or filter positioning.2:10 Metal fuel tanks, particularly those built into the cabin sole or carpentry, eventually corrode and pose significant environmental and legal risks if they leak into the bilge and are pumped overboard.1:01 Plastic tanks designed for diesel fuel offer a superior, corrosion-resistant alternative that can last the life of the vessel if properly supported to prevent stress on hose connections.2:32
