EVIL ENERGY 5/16" Submersible Fuel Hose E85 In Tank Line

EVIL ENERGY 5/16" submersible fuel hose is a SAE 30R10-rated, E85-compatible in-tank line built to handle 300 PSI working pressure and temperatures from -40°F to 212°F.

This 1-foot section of fuel hose is engineered for automotive in-tank applications where ethanol blends, gasoline, diesel or lubricants are present. With a 5/16" internal diameter and reinforced construction, it meets SAE 30R10 requirements for submersible fuel pump installations and related fuel-system uses. The hose’s compact size, consistent tolerances and high burst rating make it suitable for tight routing and reliable service inside tanks or along fuel lines.

How does this hose perform with E85 and other fuel blends?

The compound and reinforcement are specified to resist ethanol-rich fuels including E85, as well as standard gasoline and biodiesel blends. Chemical compatibility and a reinforced inner layer help prevent swelling, stiffness changes and premature failure when exposed to modern fuel chemistries.

• Rated compatible with ethanol fuels (E85, E10), gasoline, diesel and biodiesel.
• Constructed to maintain integrity when submerged in fuel tanks.
• Laboratory-style rating: SAE 30R10 standard for submersible use.

What are the physical dimensions and pressure ratings I should expect?

The hose has an internal diameter of 5/16" (approx. 8 mm) with tight manufacturing tolerances and an overall outside diameter near 14 mm. It’s designed for a sustained working pressure of 300 PSI and a bursting resistance well above that, making it suitable for most in-tank pump and return-line applications.

• Internal diameter: 5/16" (8 mm) ±0.5 mm; outside diameter ~14 mm ±0.6 mm.
• Length: 1 foot (0.3 m); minimum bend radius: 64 mm for routing care.
• Working pressure: 300 PSI; burst pressure: 1200 PSI.

Will this hose work with my installation and existing fittings?

Designed to be compatible with typical automotive fuel fittings and common hose clamps, the hose is well-suited for in-tank pump lines and fuel injection return or supply runs. Its dimensions match common 30R7/30R9 family applications, allowing straightforward replacement or retrofit in many systems.

• Fits applications for in-tank pump hoses and fuel injection lines.
• Compatible with 30R7 & 30R9 style uses and standard clamps/adapters.
• Short 1 ft length is ideal for precise repairs or assembly in tight spaces.

How does the hose handle environmental extremes and installation wear?

The material formulation and construction retain flexibility across a wide temperature range and resist degradation when submerged or exposed to fuel vapor. Its reinforcement and wall thickness give it a safety margin against pressure spikes and mechanical abrasion when routed properly.

• Temperature range: -40°F to 212°F, suitable for cold starts and hot engine bays.
• Minimized risk of collapse or pinching with a 64 mm minimum bend radius.
• Reinforced structure provides a high burst-to-working pressure ratio for durability.

Who is this for? EVIL ENERGY’s 5/16" SAE 30R10 submersible fuel hose is aimed at automotive technicians, motorsport builders and DIY mechanics who need a short, dependable in-tank or fuel-system line compatible with ethanol blends and modern fuels. Choose this hose when you require a compact, SAE-rated replacement or custom-length section that balances chemical compatibility, rated pressure capacity and ease of installation.
