Fuel Systems

Fuel systems include tanks, which may flank the engine, or stretch across the beam of the boat ahead of the engine, or both. Fuel lines may lead through manifolds that make it efficient to draw fuel from one or more tanks, and in the case of diesel engines, return unburned fuel to the proper tanks. Auxiliary bulkhead-mounted filters help keep water and foreign particles from reaching the primary fuel filter on the engine. Auxiliary fuel filtration devices, or fuel polishers, recirculate the fuel in tanks on a regular basis to minimize the chances of bad fuel reaching the engines.

In the world of marine fuel filtration there’s no shortage of opinions on the right, most reliable, and most effective set-up. There is one area, however, where opinions should not diverge, and that involves the fire resistance of the individual fuel-carrying components within the system…
