EVIL ENERGY 5/16ft Submersible Fuel Hose E85 10ft - SAE 30R10

In this review of the EVIL ENERGY 5/16' Submersible Fuel Hose E85, the bottom line is simple: this hose is aimed at DIY mechanics, custom fuel systems builders, and anyone needing a dedicated in-tank line that tolerates ethanol blends. The reviewer found its biggest selling point is reliable compatibility with E85 and a wide range of fuels while meeting SAE 30R10 submersible standards, which makes it a practical, no-frills replacement hose for submersible pumps and in-tank routing.

Key Features

• Size and fit: With a 5/16' ID and 14 mm OD, the hose fits common in-tank pump outlets and standard fittings without excessive slack or tightness.
• Submersible rating: Built to meet and exceed SAE 30R10, it is designed for continuous submersion in fuel pumps and tanks for reliable long-term use.
• Fuel compatibility: Compatible with E85, E10, gasoline, diesel, biodiesel, oil and more, so it works for vehicles that run ethanol blends or conventional fuels.
• Durability: Rated to 300 PSI working pressure and 1,200 PSI burst pressure, offering strong pressure tolerance for fuel injection or pump applications.
• Temperature range: Operates from -40F to 212F, enabling use in cold starts and high-heat engine bays or in-tank environments.
• Flexibility: A 64 mm minimum bending radius and a 10 ft length make routing through tight spaces and reach to remote pump locations straightforward.

Who It's For

This hose is best for car builders, restorers, and anyone installing or replacing an in-tank fuel pump line where ethanol compatibility is required. It suits modified engines that use E85, as well as vehicles that need a versatile hose that accepts multiple fuel types.

It is less appropriate for users who need specialty braided PTFE lines, very high-temperature exemptions above 212F, or who require a manufacturer-specified OEM branded hose for warranty reasons. Also, those wanting insulated or visually finished exterior coverings may prefer other options.

Pros & Cons

Pros

• Designed to SAE 30R10 submersible standard, providing confidence for in-tank pump use.
• Broad chemical compatibility including E85 and diesel, useful for ethanol-capable systems.
• Solid pressure ratings (300 PSI working, 1,200 PSI burst) make it suitable for many fuel system pressures.
• Ten foot length and modest bending radius make installation flexible and convenient.

Cons

• Some users report mixed durability of the outer rubber when continuously submerged, so long-term performance may vary by environment.
• The plain outer finish may not meet aesthetics or abrasion-resistance needs in exposed engine bay routing.

Frequently Asked Questions

Is this hose safe for E85?
Yes. It is specified as compatible with ethanol fuels such as E85 and E10 and is designed for submersible E85 use.

Can I use this hose for external engine bay routing?
It can be used externally within its temperature limits, but the plain outer finish may be less abrasion resistant and less heat tolerant than some braided alternatives.

Will the 10 ft length cover most installations?
Most in-tank pump installations and common routing needs are covered by the 10 ft length, and its 64 mm minimum bend radius aids routing in tight spaces.
