EPA Fuel Tank
Your Cobalt boat may be equipped with a fuel
system that has been designed and manufactured
to meet the latest U.S. Coast Guard and EPA EVAP
(evaporation) regulations. A decal located at the
helm will indicate if your boat is equipped with this
fuel system.
Some of the new features in the fuel system:
• There is no “spitback” at the deck plate when
fueling. The filler nozzle automatically shuts off
when the tank is full. Do not attempt to continue
fueling after the nozzle automatically shuts off,
indicating the tank is full.
• A carbon canister is present to capture
hydrocarbon molecules before air is vented
outside the fuel system.
When filling the tank for the first time:
• Fuel vapor will expand within the tank, causing
back pressure that may close the inlet check
valve and cause the filler nozzle to prematurely
shut off. To eliminate this problem, slowly add
only about 2 gal (7.5 L) of fuel and stop. Wait a
few minutes to let the pressure within the
system stabilize; then proceed filling the tank.
• During the first few fills, the new carbon
canister within the vent line may generate heat
from being initially saturated with
hydrocarbons and cause water droplets to emit
from the outside air vent. This is normal. After
the first two or three fills, this should not
happen.
Troubleshooting
New tank is hard to fill / nozzle keeps shutting
off:
This is called the “Green Tank Effect.” With a new
tank that has never seen fuel before, you must let
the internal tank volume become completely
filled with the fuel vapor, very similar to what
occurs in non-diurnal tanks currently. The
difference is now you do not get the huge amount
of spitback; instead the nozzle just shuts off.
When filling a tank for the first time, the fuel vapor
expands and builds back pressure, shutting the
inlet check valve and causing the nozzle to shut
off.
To eliminate this problem, add a few gallons to
the tank very slowly and let sit for several
minutes. Then proceed with normal filling.
Hot air comes out of vent and it drips liquid:
This is completely normal. When you fill a tank for
the first time, the canister becomes saturated
with hydrocarbons and generates heat as it
performs its intended function. The water from
the vent is just water vapor condensation as a
result of the carbon canister operating correctly
and stopping hydrocarbons (fuel vapor) from
venting to the atmosphere. After the first two or
three fills, the system will stabilize and these
issues will go away.
Cannot
“
top off
”
/ keep filling tank after it shuts
off:
This is due to EPA regulations preventing
overfilling the tank to prevent expansion from
causing fuel to overflow through the vent.
DO NOT CONTINUE TO FILL THE TANK ONCE
IT IS FULL AND THE NOZZLE SHUTS OFF.
