EVIL ENERGY 3/8 Marine Fuel Line Hose Type A1-15 25FT - Marine Grade

In this review the EVIL ENERGY 3/8 Marine Fuel Line Hose is evaluated as a straightforward, marine-grade replacement fuel hose for small boats and outboard motors. Its single biggest reason to buy is compliance with multiple marine and low-permeation standards, so anyone needing an SAE J1527 Type A1-15 hose that resists fuel permeation and UV exposure will find it dependable. The review focuses on build, pressure ratings and real-world fit for common marine fuel plumbing tasks.

Key Features

• Size and fit: The 3/8' inner diameter and 25 ft length make it a practical direct replacement for many small engines and fuel lines on pleasure boats.
• Pressure ratings: With a 300 PSI working pressure and 900 PSI burst pressure, the hose provides a wide safety margin for typical marine fuel system use.
• Temperature range: Rated from -20 F to 221 F, it handles both cold storage and warm engine-room environments without losing flexibility.
• Construction: NBR inner with NBR+PVC outer and polyester braid reinforcement offers chemical resistance and mechanical strength for long service life.
• Fuel compatibility: Compatible with gasoline, diesel and E85, so it works across common fuel types used in recreational marine engines.
• Regulatory compliance: Meets SAE J1527 Type A1-15, ISO 7840 Type A1 and NMMA/CE accepted standards, useful when replacing Coast Guard or manufacturer specified lines.

Who It's For

This hose is aimed at boat owners, mechanics and DIYers who need a compliant, replacement fuel line for outboards, inboards and small marine engines. It is especially useful when a product must meet low-permeation and marine type A1-15 requirements to satisfy inspections or manufacturer recommendations.

Those who should look elsewhere include owners of very large commercial vessels requiring custom high-capacity lines or applications needing extremely soft, highly flexible hose for tight routing where users reported some mixed flexibility impressions.

Pros & Cons

Pros

• Meets multiple marine and low-permeation standards, which is important for compliant installations.
• Good pressure margins with 300 PSI working and 900 PSI burst ratings for safety.
• Durable construction with NBR inner, NBR+PVC outer and polyester braid reinforcement.
• Wide fuel compatibility supports gasoline, diesel and E85 applications.

Cons

• Flexibility reports are mixed; some users may find it stiffer than expected for tight bends.
• One product length only (25 ft) means trimming is needed for shorter runs.

Frequently Asked Questions

Is this hose safe for E85 fuel?
Yes, the hose is listed as compatible with gasoline, diesel and E85, making it suitable for flex-fuel engines.

Can it be used on an outboard engine?
Yes, its 3/8' ID and 25 ft length are common for outboard fuel lines and the Type A1-15 compliance meets pleasure boat requirements.

How flexible is the hose for tight runs?
Flexibility is generally good across the rated temperature range, but some users report it can feel rigid in tight bends, so allow for an 80 mm minimum bending radius.
