Yacht Fuel System
The most important element in the yachting world more specifically in marine environment is to have dependable fuel systems on board together with all necessary equipment and accessories as a part of propulsion systems.
There is a saying among sea going people that ?a chain is only strong as its weakest link?. This is certainly applicable on the propulsion system when the diesel engines stop unexpectedly, one can experience helpless feeling and knows that the stress that these might brought problems attached to those unpleasant situations which could create. Don?t underestimate the link in the chain here which is the fuel system.
Serious manufacturer recommends products which require in operating power boats as well as sailing yachts are complete fuel systems. Complete fuel systems are composed of components like fuel tank, clean oil pump, air went, injector, hoses, standard fittings, switches, manifold, valves, some electronics like alarm sets, filters and including other safety equipments installed in confine space in the engine room from filling point to the engine.
Most importantly complete fuel system should have CE and ABYC approval which keeps environment clean not allowing any spillage of fuel into the water. This should be our main concern when we are filling the fuel tank.
Tanks: Tanks are the important part of the fuel system. It stores fuel as gasoline for the diesel engines
or petrol for petrol engines. Tanks are measured by gallon or liters in capacity. There is a big problem which tank material creates is the condensation in the tank. Condensation of humidity makes water in the fuel which could cause blockage or rust in injection systems which works very tight tolerance. Water in the fuel also could carry lots of dirt particles which might cause blockage as well. Try to use tanks which are made up of plastic or synthetic material since the heat exchange on the surface of the tank is less.
Now a day?s concern to environmental pollution brings bio diesel applications in order to enhance the performance of the diesel engines. Bio diesel added into the fuel either in the tank on board the boat or whilst in the bunker, land storage facilities, since the fuel is more susceptible to the diesel bug, the worse the problem becomes.? Try to fine seamless tanks which protect the fuel leakage. These tanks have only one opening on top of them.
Hoses: Hoses should be flexible enough to absorb the pressure which created by the fuel pump to regulate the flow of fuel in line mechanically. Hoses give flexibility in controlling the confine space most of the time maintenance service and repairs are very hard to do due to the tight space in the engine room. To make necessary connections of hoses connectors are used for easy maintenance and delivery of fuel.
Fuel Filters: Fuel filters are devices which is integral part of the fuel system, which eliminates and separates dust particles, water drops from the fuel. Water separators and fuel filters when combined, are designed to do these functions. CE and ABYC standards also come with resistance to fire in certain period of time for safety reasons.
Fuel filters are mainly two types design, spin on filter type and centrifugal type. There are some No-Smell filters for diesel engines as well. No-Smell filters remove the unpleasant smell of the diesel fuel. They are normally mounted on top of the breathing line.
Some fuel filters are designed in dual filter system which allows changing the contaminated filter cartridge easy just switching from one to other. A vacuum gauge on the filter also indicates the dirtiness level of the cartridge in order to help user to monitor. Cartridges are normally recyclable.
Fuel Safe: Fuel safe is the simple protection is used against marina thieves. Sometimes it happens in some marinas, that some people insert plastic hose into your boats filling line to siphon the fuel from your tank. Fuel safe in these kinds of circumstances, which is simple high carbon fuel resistant material which is inserted like spring into the fuel line blocks the filling line against the intruder attacks while letting the fuel go in during the supply.
Splash Stop: This appliance is directly connected to the deck entry filling plate in order to protect overflow in your fuel tank which soiling the deck and polluting the water. Splash stop provides inside reservoir to keep excess fuel over flown. This reservoir is connected to the tank and in time frame excess fuel in the reservoir drains to the tank.
