5/16ft Submersible Fuel Hose E85 In Tank Line SAE 30R10 - 5ft Durable

In this review the 5/16' Submersible Fuel Hose is evaluated for installers and hobbyists who need a reliable in-tank line that handles ethanol blends. The bottom line: it is a purpose-built, SAE 30R10-rated hose that combines clear dimensional specs with high working pressure, making it a solid pick when the main priority is a submersible-capable fuel hose that accepts E85 and other fuels. The review focuses on durability, compatibility, and real-world fit for fuel pump and injection use.

Key Features

• ID and length: 5 ft length with a 5/16' ID (8mm) provides a common size for many in-tank pump installations and allows straightforward trimming to fit.
• Pressure rating: 300 PSI working pressure and 1200 PSI burst pressure give confidence for high-demand fuel system environments and potential pressure spikes.
• Temperature tolerance: Rated from -40 F to 212 F so it maintains performance across cold starts and elevated under-hood temperatures.
• Fuel compatibility: Compatible with ethanol blends including E85, gasoline, diesel and biodiesel, making it versatile for modern engines and alternative fuels.
• Submersible design: Built to meet and exceed SAE 30R10 standards so it is suitable for in-tank, submersible pump applications where immersion resistance is required.
• Flexibility and bend radius: Minimum bending radius of 64mm gives installers a measurable guideline for routing without kinking.

Who It's For

This hose is best for automotive technicians, custom installers, and engine builders who need a short run of submersible-rated fuel hose for in-tank pumps, fuel injection lines or transmission cooler feed/return work. It suits projects where E85 compatibility and a known SAE 30R10 performance are required.

Those who should look elsewhere include users needing very long runs (this is a 5 ft length) or those who prefer pre-assembled fittings or quick-disconnect systems; this product is a raw hose intended for trimming and installing with compatible clamps and fittings.

Pros & Cons

Pros

• Meets SAE 30R10 submersible standard, so it is suitable for in-tank pump use and immersion environments.
• High working and bursting pressures provide reliability under demanding conditions.
• Wide chemical compatibility including E85 and biodiesel makes it adaptable for various fuel types.
• Clear dimensional specs and short length simplify cutting and fitting for custom installations.

Cons

• Some users may find the hose either very flexible or almost too flexible, which can make routing without kinks require careful support.
• At 5 ft it may be short for longer runs, requiring splices or additional hose sections for some applications.

Our Verdict

The 5/16' SAE 30R10 submersible fuel hose is a practical, well-specified option for installers needing a short, E85-compatible in-tank line. Its high pressure ratings and SAE submersible design make it good value for projects that require dependable fuel compatibility and immersion resistance, though buyers should plan for clamps and fittings and consider length needs before ordering.

Frequently Asked Questions

Is this hose safe for E85 fuel?
Yes, the hose is explicitly compatible with ethanol blends including E85 and E-10, so it is suitable for flex-fuel applications.

Can it be used inside a fuel tank?
Yes, it is designed for submersible use and meets SAE 30R10 standards intended for in-tank pump installations.

Will it handle high pressure from aftermarket pumps?
