LOCATION

• Locate Grade Valve per Attwood print or as deﬁned by fuel system design and tip study analysis.

• Locate in position where consumers will not kick or step on valve.

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 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 include features to allow vapor and liquid fuel to pass the valve in order to ensure the inlet valve does not create an accidentally sealed fuel tank/system.

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.

and workmanship and are designed, built, and equipped to conform at the time of sale to Boat Company with the 40CFR.1060 requirements. For two (2) years from the date of a Program Boat’s ﬁrst retail sale, Attwood will, at its sole option, repair or replace any components that fail due to a defect in material or workmanship. ATTWOOD PROVIDES NO WARRANTIES WITH RESPECT TO ANY PART OR COMPONENT NOT MANUFACTURED BY ATTWOOD, INCLUDING FUEL TANKS. Boat Company is responsible for the installation of all Systems, whether installed by Boat Company or under its direction.

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 Grade Valves 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.

FEATURES:

Allows fuel vapor to vent from tank during normal operation. Used in combination with the Fill Limit Vent Valve, the Grade Valve allows proper venting when the fuel tank is at unusual angles/attitudes. Eliminates the possibility of liquid fuel reaching the carbon canister or vent system during vessel operation, trailering and storage. For use with speciﬁc fuel tank geometries

REQUIRED FOR INSTALLATION

• 5/16" (8mm) I.D. Vent Hose

• Hose Clamp, trade size 006, 300-grade all-stainless (both band and screw)

• 1/4" (6mm) Nut Driver or small Flathead Screwdriver for Hose Clamp Installation

• (6) Stainless Steel / rubber washers (self sealing) 300 series for use on aluminum tanks

• (6) Stainless Steel washers 300 series for use on plastic tanks

• 5/16" Nut Driver for Grade Valve Installation to Tank

• Torque monitoring device to ensure proper torque level for all fasteners

INSTALLATION INSTRUCTIONS

1. Ensure that the valve mounting surface on the tank is smooth, ﬂat and free of defects to ensure optimal seal performance.

2. Install the gasket, aligning all six (6) clearance holes with the mounting holes on the tank surface. Both sides of the gasket are identical.

3. Install grade valve assembly, aligning the 5/16" (8mm) port with what is speciﬁed on the drawing (unless a separate mark has been made on tank for identiﬁcation). Align six (6) clearance holes with the mounting holes on the tank surface.

4. Loosely install six (6) #10-24 x 3/4" stainless steel fasteners and stainless steel washers. Torque each fastener to 25 in-lbs. in the sequence shown in Figure 2:

5. Loosely install one (1) all-stainless, trade size 006 hose clamp over 5/16" (8mm) hose.

6. Insert hose onto 5/16" (8mm) port, ensuring that the end of the hose bottoms out on the main side wall of the valve. Hose must connect to Fill Limit Vent Valve (99FLN and 99FLF Series)

7. Install hose clamp 1/4" (6mm) from end of hose, orienting clamp as shown in Figure 1, with clamp head and body ﬂush/underﬂush with Grade Valve assembly. Fasten hose clamp to 18 in-lbs.

NOTES:

• Inspect screw torque annually

• Do not step on Valves

• 1/2" (12mm) Clearance required around component

• Pressure test tank to ensure connection integrity per CFR 33 183.580 at pressure of

3 psi for no less than 10 minutes. Inspect all connections for leaks by method other than pressure decay.

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;
