Fuel System
189FS Tank
The 189FS is equipped with a single, 40 Gallon, pressurized fuel tank. The tank is of Polyethylene construction and is secured/insulated with foam
during the construction of the boat. The tank is located on centerline between the aft livewell and aft end of the console. There is a sending unit
installed in the tank. Inspection ports in the deck and head compartment provide access to tank fittings. The 189FS fuel system “breathes” through a
carbon canister located in the anchor locker that vents overboard through a vent on the starboard side of the hull.
203FS Tank
The 203FS is equipped with a single, 60 Gallon, pressurized fuel tank. The tank is of Polyethylene construction and is secured/insulated with foam
during the construction of the boat. The tank is located on centerline between the aft livewell and aft end of the console. There is a sending unit
installed in the tank. Inspection ports in the deck and head compartment provide access to tank fittings. The tank vents though the gas fill that
incorporates a cap that allows air to move into and out of the tank.
Fuel Supply
There is a fuel pickup installed in the tank. The pickup incorporates a shut off valve along with an anti-siphon valve than can be accessed through the
in deck inspection plate under the leaning post. There is an on deck fuel fill located on the port side of the boat, just forward of the console. Access to
the fill is provided through an inspection port. The fuel fill also incorporates a vent that allows venting of the tank, It is recommended that these
connections be inspected annually.
The 189FS/203FS will come pre-rigged from the factory with an engine matched fuel water separator. The fuel water separator is installed in the
bilge and accessed through the bilge access hatch located in the splash well. The Fuel Water separator should be checked periodically to ensure the
fuel is free of water. Fuel should be disposed of in an approved waste collection device when servicing/replacing. The filter must be filled with fuel
after servicing/replacing them in order to prime the engine. A primer bulb for the engine is located in the engine splash well. It is used to prime the
engine and system before starting the engine. This should be done after service or after periods of downtime for the boat. When fueling your boat,
whether on trailer or at a marina, the pressurized system will prevent overfilling. Any blockage of the vent and or vent line will prematurely trigger
the shut off on the fuel nozzle and will prevent you from filling the tank completely. It is recommended to inspect your fuel system annually to
ensure that all hose fittings are secured and the lines are free of any kinks. All components of the 189FS and 203FS fuel systems are approved for use
with ethanol blended fuels up to 10%. E85 fuel should never be used. Key West recommends using non ethanol fuels whenever possible to reduce
the risk of moisture retention in the fuel system, especially in areas of high heat/humidity.
Due to the emission requirements of the EPA, certified fuel tanks and systems will not fill to the top of the tank. Instead, there will be a ullage in the
top 10% of the tank. The specified capacity of the tank accounts for this ullage when the tank is static and level. Therefore, it is important to make
sure the boat is as level as possible when filling the tank. Any forward or aft tilt will cause fuel to collect in one end of the tank and prematurely reach
either the forward or aft tank vent. When fuel reaches these vents, it triggers the shut off. When the boat is level, fuel will reach these vents at the
same time and allow the maximum quantity of fuel into the tank. The tanks ullage will also affect your fuel gauge as the tanks sending unit will not
reach the top of the tank, even when the tank is filled. This will cause the fuel gauge to not read full, even though it is. Do not rely on the fuel gauge
exclusively as variations will occur.
The stated capacity of the tank
DOES NOT
reflect the quantity of usable fuel in the tank. The tank and its pickup are designed to allow as much fuel to
be used as possible when on plane or in the boat’s level floating position, but it will not allow all fuel to be used. When using your boat, it is a good
practice to keep a log and a running count of how much fuel you’ve used.
