EVIL ENERGY Marine Fuel Line Hose 5/16" 25ft - SAE J1527 Type A1-15, Low-Permeation NBR

EVIL ENERGY 5/16" Marine Fuel Line Hose Type A1-15 is a 25-foot, reinforced rubber fuel hose engineered for boats, meeting SAE J1527 and low-permeation marine standards.

This heavy-duty marine fuel line combines a nitrile rubber (NBR) inner core with an NBR+PVC outer cover and a polyester fiber braid to deliver dependable fuel delivery in boating applications. Built to tolerate gasoline, diesel and ethanol blends, the hose is rated for a wide temperature range and elevated working pressures, while conforming to low-permeation and industry safety specifications for recreational vessels.

How does this hose handle common marine fuels?

The hose is formulated to resist degradation from gasoline, diesel and fuel blends such as E85, thanks to its NBR inner layer. That composition helps preserve fuel flow and reduces swelling compared with non-specified materials.

• Compatible with gasoline, diesel, and ethanol blends (E85).
• NBR inner tube resists chemical attack and fuel softening.
• Designed to limit permeation for cleaner onboard air and reduced vapor loss.

What pressure and temperature ranges can I expect?

This 5/16" hose supports a maximum working pressure of 300 PSI with a burst pressure up to 900 PSI, giving a substantial safety margin for most outboard and inboard fuel systems. It also remains flexible from cold start conditions to warm climates, spanning common marine operating temperatures.

• Maximum working pressure: 300 PSI; burst pressure: 900 PSI.
• Operational temperature range: -20°F to 221°F (-30°C to 105°C).
• Durability under thermal cycling to handle seasonal boating use.

Does it meet marine safety and emissions standards?

The hose meets multiple recognized marine and emissions standards, including SAE J1527 (type A1-15) and ISO 7840 type A1, and satisfies NMMA/CE acceptance criteria. It is designed to meet EPA and CARB very low permeation requirements, reducing vapor release and complying with stricter environmental rules.

• Certified to SAE J1527 type A1-15 and ISO 7840 type A1 requirements.
• Meets EPA and CARB very low permeation standards for fuel hoses.
• UV- and weather-resistant outer layer for longer service life outdoors.

How does construction affect installation and longevity?

The hose’s NBR inner tube and NBR+PVC outer cover produce a balance of flexibility and abrasion resistance, while the polyester braid reinforcement controls expansion under pressure. Together those materials make routing easier in tight engine compartments and extend service intervals compared to non-reinforced hoses.

• Polyester fiber braid reduces hose stretch and improves pressure handling.
• NBR+PVC outer jacket resists abrasion, sunlight and weathering.
• 25-foot length minimizes the need for multiple joins in many installations.

Who is this for: The EVIL ENERGY 5/16" Marine Fuel Line Hose is intended for boat owners, marine mechanics and DIY restorers who need a compliant, durable fuel line for recreational vessels. It’s a practical choice when you require a hose that handles gasoline, diesel or ethanol blends, meets industry standards, and resists UV and weather exposure for dependable onboard performance.
