• Compare dimensions and weights before choosing a capacity
• Gasoline and diesel are among the liquids listed as compatible by Techno Tanks

Start With the Standard Marine Fuel Bladder Specifications

A marine fuel bladder specification starts with capacity, filled dimensions, bladder weight, liquid compatibility, and the connections required for filling and discharge.

Techno Tanks offers standard marine fuel bladder sizes from 30 to 300 gallons, plus custom configurations for specialized applications.

Core Fuel Bladder Specification Factors

Fuel Bladder Materials

Fuel bladder materials must be selected around fuel compatibility, storage conditions, transport requirements, and environmental exposure.

Techno Tanks standard marine fuel bladders are made from thermoplastic polyurethane (TPU), a flexible material used across the standard 30–300 gallon range.

• Thermoplastic polyurethane (TPU) construction
• Flexible, collapsible bladder design
• Confirm liquid compatibility for the intended application before ordering
• Custom configurations are available when a standard size does not fit the application

Capacity and Dimensions

Fuel bladder capacity is usually specified in gallons or liters, but capacity alone is not enough. The bladder must also fit the available space and support the intended deployment method.

• Custom capacity based on required fuel volume
• Custom dimensions based on available space
• Flexible sizing for decks, compartments, vehicles, staging areas, and remote sites
• Shape and placement planned around actual use conditions

Fittings, Inlets, Outlets, and Transfer Points

Fittings determine how the fuel bladder is filled, vented, connected, transferred, and emptied.

For technical buyers, fitting placement is not a minor detail. It affects usability, transfer control, safety, and deployment.

• Custom inlet configuration
• Custom outlet configuration
• Vent options based on application
• Hose, pump, and transfer connection planning
• Placement based on fill/discharge workflow

Fuel Compatibility

Fuel compatibility must be confirmed before selecting a bladder configuration. Different fuel applications may require different material, fitting, and handling considerations.

• Diesel fuel bladder configurations
• Gasoline fuel bladder configurations
• Other compatible liquids should be confirmed for the intended application
• Specialized fuel applications reviewed by intended use

Safety and Compliance

Fuel bladder safety depends on correct material selection, fuel compatibility, construction quality, deployment conditions, and proper configuration.

• Use only with liquids listed as compatible by Techno Tanks
• Confirm capacity, dimensions, placement, and connection requirements before use
• Follow the operating instructions for placement, filling, use, and storage

Supported Use Environments
