Fuel Systems
The fuel systems aboard your Hunter yacht consists of
the following components or sub-systems.
• Fuel Tank
• Fuel Fill
• Fuel Vent
• Fuel
• Lines
• Fuel Filters
• LPG (Liquefied Petroleum Gas) System

5.1 Fuel Tanks

Your boat is equipped with a fuel tank, having a total
capacity of 150 gallons (568 Liters). In the aft stateroom
under the bunk.
The tank is filled through a fuel fill (5.2), on the Stbd. aft
side of the boat.
If your boat has a metal or aluminum tank installed, then
the fuel tank should be inspected for signs of leaks, cor-
rosion, and/or pitting at least once a year. Corrosion
normally appears as a white, chalky, or flaky substance
on the surface of the tank. Sometimes, it also appears
as pitting or small pockets of missing aluminum. Another
indication of corrosion is bubbles on the paint that coats
the tank. If any of these conditions are present, have an
authorized service technician inspect the tank immedi-
ately. If a leak is found, turn off battery switches and dis-
connect shore power (See Connecting & Disconnecting
Shore Power, AC Electrical System), which explains
the proper way to disconnect and disable any possible
source of ignition). Contact your dealer or Customer
Service immediately.
5.1.1 Fuel Tank Capacity Monitoring
The fuel tank is equipped with a fuel level sending
unit, which provides an electrical signal to the multi-
purpose display located at the helm. The monitor (Fig.
5.1) also handles engine monitoring and general baot
data from all connected items to this unit, and will
allow the same to be displayed in a variety of formats.
This monitoring system
screen call up that is easily read at day or night.
Be sure and review the documentation for this monitor
supplied to you by the manufacturer.

5.1.1 Fuel Tank Grounding System
The fuel tank and fuel fill on your boat are electrically
grounded to the engine negative. (see the DC Electrical
chapter). This grounding system is designed to prevent
the discharge of static electricity when fueling your boat.
An authorized service technician should inspect this sys-
tem at least once each year.
5.1.2 Fuel Gauge
The fuel gauge as shown in Fig. 5.1 is located at the
helm, and is the indicator of the fuel level in your tank.
Visually inspect the reading against what is show-
ing in the tank to see that the gauge is operational.
!
Never enter the engine room without proper ventila-
tion first. A spark caused by power tools or lighting
equipment could result in fire or explosion which
could cause personal injury or death.
