FUEL SYSTEM
Fuel Requirements
Low sulfur #2 diesel fuel or #1 and #2
commercial winter blend diesel fuels are the
most common commercially available and
recommended for use.
The use of #2 diesel fuel will result in
optimum engine performance. Obtain fuel
from sources that are replenished often, such as
large truck service facilities where fuel supplies
are fresh and the possibility of contaminants
is reduced. It is important to not empty the
engine of fuel. The fuel system on the engine
is sensitive to air. If the engine is allowed to
run out of fuel, the fuel system will need to be
thoroughly primed before the engine will start.
WARNING:
DO NOT mix gasohol with diesel fuel.
This mixture can cause an explosion.
NOTE:
Due to the precise tolerances of diesel
injection systems, it is extremely
important that fuel be kept clean and
free of dirt or water. Dirt or water in the
system can cause severe damage to both
the fuel pump and the fuel injectors.
Fuel additives for lubricity are not
recommended. There are numerous
diesel fuel additives to help remove
moisture from fuel, prevent microbe
growth and to prevent gelling during
cold weather. Before adding any type
of fuel additive or extender, consult the
Manufacturer’s Owner’s Manual.
Fuel Tank
Pick-up and return lines are placed at opposite
ends of the tank to inhibit fuel aeration. The
engine pickup tube is cut at a 45° angle to allow
optimum fl ow to the engine. The generator
intake tube is set to approximately ¼ of a tank.
This will prevent depleting the fuel supply while
dry camping.
Internal baffl es slow fuel slosh. A check
valve placed at the bottom of the baffl e, at the
end of the tank with the pick-up tube, prevents
fuel starvation through long corners when fuel
supply is low.
NOTE:
Fill the fuel tank if the motorhome is
going to be stored for any length of
time to reduce the amount of potential
condensation. After storage, check
the vent tube for blockage. It is not
uncommon for insects to plug the vent
tube. If pressure or vacuum exists when
the fuel cap is removed, the vent tube
may be blocked. The end of the vent
tube is located on the curbside of the
fuel tank, near the bottom.
Fuel Sender
The Centroid fuel sender has no moving parts
and works by measuring electrical property
between inner and outer tubes in the tank. The
more fuel between the tubes the higher the
reading. Electronics in the head of the sender
convert the capacitance to current to drive the
fuel gauge.
Connections:
The Centroid sender has four connections:
Positive (POS) and Negative (NEG):
Battery voltage to run the electronics in the
sender head.
SEND:
Connects to the SEND terminal of
the gauge on the dash.
ALARM:
Makes a connection internally to
the negative (NEG) terminal when the low fuel
alarm level is reached (when the fuel gauge is
reading about 1/8 tank). This turns on the fuel
indicator on the liquid crystal display on the
speedometer and is not adjustable.
