Quicksilver 810 Arvor — System & Component Overview and Operation

1. Fuel System

Your boat's diesel fuel system consists of a fuel tank, a fuel tank fill and vent fitting, a sending unit, a
shutoff valve, an engine fuel supply line, and an engine fuel return line. In addition, there is an inline
fuel filter to provide the adequate level of filtration for the system.

Fuel Tank
Your boat is equipped with a crosslink polyethylene fuel tank with a capacity of 300 liters. As a
precaution, all of the capacity may not be useable due to trim and loading conditions, so consider
keeping at a minimum 25% reserve fuel in the tank.
Fuel tanks with levels less than 25% capacity can cause engine stalling problems due to fuel starvation
or by allowing sediment and dirt to enter the fuel supply lines. Keep the tank full and monitor the fuel
level often to prevent this from happening.
Fuel Distribution
Fuel is delivered from the tank to the engine through the shutoff valve and the fuel feed line. The
shutoff valve, located on the starboard aft side of the cockpit behind an access plate, is a safety
feature designed to prevent fuel from siphoning out of the tank if the fuel feed line was ever cut or
broken below the level of the fuel in the tank. If the feed line ever broke, you can close the valve to
prevent the entire contents of the tank siphoning into the boat.
Filling The Tank
It is best to maintain a full tank of fuel when the engine is not in use. This will reduce the air flow in
and out of the tank due to changes in temperature.
When filling the tank, do not attempt to top off the tank. When the nozzle shuts off, the tank is full,
and continuing to fill past the fuel fill shutoff will cause the system to spit fuel back.
Fuel / Water Separator
The engine is provided with an element-type fuel filter built into the engine, however, to eliminate
water and dirt, a 10 micron primary fuel / water separator is installed in the system.
Maintenance
Periodically inspect for the presence of water in the fuel tank. If any is found, all water must be
