Moeller Portable Fuel Tank 12 Gallon (45L) Low-Profile — UV-Stabilized HDPE, Two-Stage Vent Cap

This compact, high-profile tank pairs durable one-piece construction with a partitioned bottom that creates a reserve fuel area, making it a reliable choice for boating, work boats, and mobile equipment. Engineered to conform with EPA and CARB permeation rules and built to current U.S. Coast Guard and ABYC standards (for tanks 12 gallons and under), the Moeller 630012LP balances regulatory compliance with practical features like a two-stage self-venting cap and a shape optimized for tight storage spaces.

How does the tank control fuel vapor and meet environmental rules?

The Moeller 630012LP uses a two-stage self-venting cap that significantly reduces vapor release and aligns with EPA and CARB low-permeation requirements introduced in 2011. The tank material and manufacturing approach also minimize permeation through the polyethylene walls while maintaining durability.

• Two-stage self-venting cap designed to limit vapor escape
• Low-permeation HDPE with ultraviolet inhibitors
• Manufacturing methods focused on consistent, low-leak performance

What makes this tank easy to store and carry in tight spaces?

Although described as a high-profile design, the 630012LP features a slim footprint and a seamless one-piece shape that slides into narrow lockers and small compartments. The molded form also provides stable placement on flat surfaces to prevent unwanted movement during transport or storage.

• Low-profile dimensions for compact storage
• Seamless one-piece construction reduces bulk and snag points
• Stable shape that fits small boat lockers or service vehicle racks

How does the built-in reserve fuel area work and why is it useful?

This model incorporates a partitioned bottom that creates a reserve chamber to capture remaining fuel as the main tank drains. The reserve helps prevent sudden fuel starvation and gives you a margin to reach shore or a service point when levels are low.

• Partitioned bottom forms a reserve section for added security
• Helps avoid unexpected engine fuel starvation during low levels
• Useful for longer trips, auxiliary power systems, and work applications

Is this tank compatible with U.S. Coast Guard and ABYC standards?

Yes — all Moeller portable tanks of 12 gallons and under, including the 630012LP, meet current U.S. Coast Guard and ABYC standards. That compliance reflects both material selection and the tank’s venting and sealing design.

• Meets U.S. Coast Guard requirements for small portable tanks
• Conforms to ABYC recommendations for marine fuel systems
• Designed to fit regulatory and practical marine usage

Who is this for: The Moeller 630012LP is intended for boaters, marine technicians, and professionals who need a regulated, compact, and reliable portable fuel source. It suits owners of small craft, service vessels, and mobile equipment that require EPA/CARB-compliant containment with easy storage, a safety-minded reserve feature, and robust construction for regular use.
