Fancat 3/8" Marine Fuel Line Hose 25 ft - SAE J1527 Type A1-15, NBR/PVC Reinforced, UV & Saltwater Resistant

Fancat's 3/8" marine fuel line hose is a 25-foot, SAE J1527 Type A1-15 rubber hose built to carry gasoline, diesel and E85 safely for boats and outboard engines.

This high-performance marine fuel hose combines a nitrile (NBR) inner layer with an NBR/PVC outer jacket reinforced by a polyester braid to resist oil, heat, UV and saltwater. Designed to match common 3/8" (9.8 mm) system fittings, it delivers reliable flow and low permeation for small vessels, dinghies, pontoons and engine rooms where a compact, durable fuel line is required.

How does this hose handle different marine fuels?

The hose is formulated to be compatible with gasoline, diesel and ethanol blends such as E85, and it meets SAE J1527 Type A1-15 certification for marine fuel hoses. That certification indicates the materials and construction are appropriate for common marine fuel exposures without premature degradation.

• Compatible with gasoline, diesel and ethanol blends (E85).
• SAE J1527 Type A1-15 certified for marine fuel service.
• Low permeation design meets EPA/CARB requirements.

Will it fit my boat's fuel system and hardware?

The hose has an inner diameter of 3/8" (9.8 mm) and an outer diameter of 17.3 mm, matching standard 3/8" marine fuel fittings and clamps. With a 25-foot length and a minimum bend radius of 3.15" (80 mm), it is sized for routing through tight bilges and around engine components.

• ID: 3/8" (9.8 mm) — fits typical 3/8" barbs and quick-connects.
• OD: 17.3 mm and 25 ft length for flexible installation runs.
• Minimum bend radius: 3.15" (80 mm) for compact routing.

How durable and safe is the hose under marine conditions?

Constructed with an NBR inner layer and NBR/PVC outer jacket reinforced by polyester braid, this hose resists oil, heat, UV and saltwater corrosion. It is rated for 300 PSI working pressure and 900 PSI burst pressure, and operates across a wide temperature range, making it suitable for coastal and offshore environments without rapid deterioration.

• Working pressure: 300 PSI; burst pressure: 900 PSI.
• Temperature range: -104°F to 221°F (-40°C to 105°C).
• UV and saltwater resistant with polyester braid reinforcement.
