Engine & Controls
take out some small debris as well as small amounts of water. Fuel
fi lters are not able to remove large amounts of water. If the fuel
becomes contaminated with water, the fuel must be run through a
fuel polisher available at select marinas to remove large amounts of
water.
Fuel Injectors
Aft er the fuel has passed through the fuel pumps and fi lter, it is ready
to be injected into the engine. Because boat engines run off four
strokes (intake, compression, spark, exhaust), fuel must be delivered
to the appropriate cylinders at the appropriate time for optimal
engine performance. Th
is action is performed by fuel injectors that
inject an air and fuel mixture into the engine cylinders.
Fuel Sender & Gauge
A fuel sender on the fuel gauge uses a dipstick/fl oat system to measure
the amount of fuel left in the tank. Th
is measurement generates a
specifi c resistance value in an electronic circuit connected to the fuel
gauge at the helm. As diff erent fuel levels are reached, the resistance
value in the circuit with the fuel gauge changes which is read by the
fuel gauge and is converted to an approximate fuel level.
Fuel Tank
Th e fuel tank should be inspected before each cruise. Th is should
be done when you check the fuel lines for tightness and leaks.
Your Regal boat uses an aluminum or polyester fuel tank that has
been tested several times along with other fuel system components
for safety requirements and dependability in house, and they
are inspected independently by National Marine Manufactures
Association personnel.
