SAVE THESE INSTRUCTIONS
CAUTION:
The vessel manufacturer must comply with the
requirements of CFR 40 1060.202. Any questions can be
directed to www.attwood.com
Failure to follow these instructions may result in accidental
fuel system over-pressurization. Users must follow these
instructions to ensure vessel function and operation
EMISSION-RELATED INSTALLATION INSTRUCTIONS
Failing to follow these instructions when installing the Attwood 99CC
series Carbon Canisters in a piece of nonroad equipment violates federal
law (40 CFR 1068.105(b)), subject to fines or other penalties as described
in the Clean Air Act.
CARBON CANISTER INSTALLATION INSTRUCTIONS:
Federal regulations (CFR 40 1060.101 (f) (1) (iii)) require that the fuel system is
designed so that liquid fuel and/or liquid water can not reach the carbon canister. This
ensures that the carbon does not varnish or degrade which can result in the reduction
of the performance of the carbon canister and its ability to perform the required
evaporative emission control.
Take the following steps to ensure liquid fuel and/or liquid
water does not reach the carbon canister
1. Install Attwood 99FL and/or 99GV series vent valves in the vent line between any
liquid fuel reservoir and the Carbon Canister. Install the Attwood 99FL between the
carbon canister and any 99GV series vent valves. The Attwood 99FL and 99GV series
valves have been validated to ensure liquid fuel does not reach the vent line and/or the
Carbon Canister during vessel storage, operation and maneuvering due to sloshing,
filling or expansion of the fuel. Follow all installation instructions for the 99FL and
99GV series Grade Valves to ensure safe and proper function. The Attwood carbon
canister can be mounted in any relative position to the fuel tank when Attwood 99FL
and Attwood 99GV series valves are installed in the vent line between any liquid fuel
reservoir and the Attwood Carbon Canister.
Note: Installations relying upon self draining vent/fuel lines as the method of
preventing liquid fuel from reaching the canister do not meet the criteria for preventing
liquid fuel from reaching the carbon canister.
2. In order to prevent liquid water from reaching the carbon canister, install Attwood
1674 Series P-trap Vent in the vent line after the Carbon Canister. Follow all
installation instructions for the Attwood 1674 Series P-trap Vent.
Important safety instructions
(for all Attwood 99FL/99GV/99CC/99ICV/99DF components):
When a fuel system is configured with Attwood 99FL and/or 99GV series vent valves
the following safety precautions must be taken;
1. Use an Attwood 99ICV series Inlet Control valve between the liquid reservoir and
the deckfill to prevent the accidental wellback of fuel. Use only an Attwood 99ICV
series Inlet Control Valve in-line with the fuel fill hose. No other fill hose valves
should be installed in order to ensure the safety of the fuel system and vessel. The
Attwood 99ICV series inlet control valves includes features to allow vapor and liquid
to pass the valve in order to ensure the system does not become accidentally over
pressurized.
2. Use only an Attwood 99DF series Deckfill. The Attwood 99DF series Deckfill includes
overpressure relief safety valves that allow unintended pressure to be released in the
event that the tank becomes accidentally overfilled and/or over pressurized.
REQUIRED FOR INSTALLATION
• Bracket-hull mount: Phillips screwdriver , flat head screwdriver, and hex key, or hex
socket (depending on fasteners selected)
• Bracket-canister mount: hex socket
• Pilot drill for mounting screws
• #10-24 GH3 tap (optional for aluminum construction
• Four (4) #10 stainless steel pan or flange head screws (for bracket mount to hull)
• Two (2) .25"-20 X .75" (or .25-28 UNF) stainless steel fasteners. Flanged head with
.625" minimum flange diameter acceptable.
• Two (2) self locking, nylon insert or deformed thread, stainless steel hex nuts which
meet ANSI/ASME B18.2.2 (i.e. 7/16" hex)
• Two (2) stainless steel flat washers of .625" minimum diameter if flange headed
fastener is not used.
LOCATION
1. Mount on a flat surface where risk of torsional loads being applied to the canister is minimal
2. If mounted within the engine compartment, the canister must be equipped with a
heat shield (99CC030HS1, 99CC085HS1, 99CC150HS1). Please refer to your Carbon
Canister Heat Shield instruction sheet for details.
3. For aluminum construction, the bracket must thru-fasten. If the substrate is of sufficient
thickness, they may be installed by drilling and tapping the aluminum substrate.
4. For fiberglass construction, the substrate must be of sufficient thickness, with a
fiberglass-wood, or similar, laminate construction.
5. The carbon canister must be installed using the provided brackets.
6. Do not install canister where it can be stepped on.
7. When possible, install carbon canister above top surface of tank to allow self draining
lines (not required).
MOUNTING INSTRUCTIONS (Figure 1)
Horizontal orientation
1. Select a flat mounting surface high above the bilge, clear of moisture from spray or deck wash.
2. Using mounting holes which have direct access with driver, with canister installed in
the horizontal position (2 per bracket), mark mounting holes.
3. Drill holes for #10 screws and secure unit in place using stainless steel screws.
Do not over tighten screws.
4. With hardware provided, tighten bolt to nut at 58

3 in-lb torque.
Vertical orientation
1. Select a flat mounting surface high above the bilge, clear of moisture from spray or deck wash.
Note: the brackets may be on the same side or opposite sides in the vertical position.
2. Using the two (2) mounting holes which have direct access with driver and are at
opposite corners with canister installed in the vertical position (2 per bracket), mark
mounting holes.
3. Drill holes for #10 screws and secure unit in place using stainless steel screws. Do not
over tighten screws.

Hose Installation
1. Use 5/8" I.D. A1 or A2 vent hose to connect to the inlet and outlet of the Carbon
Canister. If the vent line is self draining AND located outside of the engine.
compartment, then 5/8" I.D. B1 or B2 hose may be used.
2. Install vent hose from the FLVV to inlet of the canister and from the outlet of the
canister to the Attwood 1674 P-trap Vent.
3. All hose connections must be sealed and pass 3psi leask test per CFR 33 requirements
(canister may not be pressurized to more than 3 psi).
4. All connections must be inspected annually.
Note: During the first refueling event, the canister will heat up due to the
carbon being activated for the first time.
MANUFACTURER REQUIREMENTS
The information below applies only to EPA CFR 40 1060.135. The vessel manufacturer
is responsible to meet all additional regulatory labeling requirements including EPA,
CARB, USCG and others as necessary. The below information is for reference only.
The vessel manufacturer should refer to CFR 40 for complete labeling guidelines.
In order to meet the requirements of CFR 40 1060.135, the vessel must be labeled with
respect to evaporative emissions in the following manner when installing
certified components;
Excerpt from CFR 40 1060.135
(a) You must affix a permanent and legible label identifying each engine or piece of equipment before
introducing it into U.S. commerce. The label must be—
(1) Attached in one piece so it is not removable without being destroyed or defaced.
(2) Secured to a part of the engine or equipment needed for normal operation and not normally
requiring replacement.
(3) Durable and readable for the equipment’s entire life.
(4) Written in English.
(5) Readily visible in the final installation. It may be under a hinged door or other readily opened
cover. It may not be hidden by any cover attached with screws or any similar designs. Labels on
marine vessels must be visible from the helm.
(c) If you produce equipment without certifying with respect to evaporative emissions, the equipment
label specified in paragraph (a) of this section must—
(1) State: ‘‘MEETS U.S. EPA EVAP STANDARDS USING CERTIFIED COMPONENTS.’’
(2) Include your corporate name.
Below is an example of a label specified by CFR40 1060.135 for use with certified
components;
