Fuel Hoses
Fuel hoses transport gasoline from one component to another.
ese hoses are required to be of certain diameters in order to
comply with engineering standards. Hose clamps are o en used to
seal the hose to a tting, and should be checked regularly.
Fuel Pumps/Filter
From the fuel tank, gasoline is moved from the tank to the engine by
the pressure produced in fuel pumps. Fuel lters are used to catch
debris and water. Typically, a fuel lter is located before the engine
fuel pump and a water separator lter is found between the fuel tank
and the outboard engine.
Fuel Sender & Gauge
A fuel sender on the fuel gauge uses a dipstick/ oat system to measure
the amount of fuel le in the tank. is measurement generates a
speci c resistance value in an electronic circuit connected to the fuel
gauge at the helm. As di 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
e fuel tank should be inspected for damage before each voyage.
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. Typical fuel tank and hoses shown below.
