It is a good idea to inspect your fuel tanks every so often. Keeping them dry and well secured is vital for toruble free cruising. It also helps to check other components that come in contact with the tanks. Having piece of mind is a good thing.
Putting together a fuel delivery system is best done by taking a high level view and making it as simple, as accessible, and as futureproof as possible. Eliminate unnecessary fittings, use fire rated, CG-approved fuel hoses and high pressure fittings, and your system should be reliable and trouble free for the life of the boat.
