The best 5/16-inch submersible fuel hose depends on whether you need a short repair piece, extra hose length, included clamps, or a flexible pump connection. The EVIL ENERGY hose is a straightforward one-foot option with stated pressure and temperature specifications; the Meonum listing is a two-pack with clamps; and the five-foot hose suits longer runs. The corrugated two-pack is specifically described for select Walbro pumps. Compare inner diameter, length, fuel compatibility, and installation needs before choosing.

EVIL ENERGY 5/16-Inch Submersible Fuel Hose

This one-foot hose is listed with a 5/16-inch inner diameter, 14 mm outer diameter, 300 PSI working pressure, and 1,200 PSI burst pressure. Its stated operating temperature range is -40°F to 212°F, and the listed minimum bending radius is 64 mm. The product information identifies compatibility with gasoline, ethanol blends including E85 and E10, diesel, biodiesel, oil, and gas.
Best for: A buyer replacing a short in-tank section who wants published pressure and temperature figures. It was selected for its explicit fuel compatibility and compact length. Limitation: At one foot, it may not provide enough material for a longer repair, and its upper stated temperature is lower than some options here.
Meonum Two-Pack With Clamps

The listing describes two one-foot hoses with 5/16-inch inner diameters and 14 mm outer diameters. It identifies the hose as meeting SAE J30R10 requirements for in-tank service and says it is suitable for gasoline, diesel, and ethanol-blended fuels up to E85. The product title says clamps are included. Its listed construction has a fuel-resistant synthetic-rubber inner tube, braided reinforcement, and a synthetic-rubber outer cover.
Best for: Buyers who want two short sections and the listed clamps for an in-tank project. The two-piece format and stated J30R10 application make it a useful comparison choice. Limitation: The supplied product details do not state a working-pressure rating or temperature range, so verify those requirements if they matter for your setup.
5/16-Inch SAE 30R10 Hose With Clamps

This one-foot hose is listed for in-tank installation and has a 5/16-inch inner diameter and 14 mm outer diameter. Its product information identifies SAE 30R10 and compatibility with E85, E10, gasoline, and diesel. It also describes an ethanol-resistant fluorine-rubber inner layer. The title states that two hose clamps are included.
Best for: A buyer seeking a short SAE 30R10 section with compatibility information focused on common gasoline and diesel fuels, including ethanol blends. It was selected as another compact repair option. Limitation: The supplied feature details do not give pressure or temperature ratings, so compare the listing against the vehicle or pump requirements before purchase.
Five-Foot 5/16-Inch Submersible Fuel Hose

This option provides five feet of hose with a 5/16-inch inner diameter and approximately 13.9 mm outer diameter. The listed material is NBR. Product specifications state a maximum working pressure of 400 PSI, burst pressure of 1,300 PSI, and operating temperature range of -40°F to 275°F. Listed compatible liquids include gasoline, diesel, biodiesel, oil, grease, water, and ethanol fuels including E85 and E10.
Best for: Buyers who need more hose length than a one-foot section and want stated pressure and temperature parameters. Limitation: Its five-foot length may be unnecessary for a small repair; check the required dimensions and cut length for your application.
Corrugated Fuel Pump Hose Two-Pack

This package contains two corrugated 5/16-inch (8 mm) by 6-inch (150 mm) fuel-line sections. Its product information specifically identifies Walbro 450, 525, and 550 fuel pumps and says the hose is compatible with E85. The corrugated design is described as flexible for tight bends inside a tank.
Best for: Buyers whose fuel-pump application matches the listed Walbro models and who need short, flexible connections. It stands apart from the straight one-foot and five-foot hose options. Limitation: The stated pump compatibility is specific; do not assume it suits a different pump or connection without checking dimensions and fit.
Buying Guide: Choosing 5/16-Inch Submersible Fuel Hose
Does the hose need to be rated for in-tank use?
Yes, when the hose will be submerged in fuel inside a tank. Look for an explicit in-tank or submersible application and check the stated specification, such as SAE J30R10. A hose intended only for external fuel-line use may not be suitable for immersion. Confirm that the selected product meets the requirements of the vehicle, pump, or repair.
How much hose length do you need?
One-foot sections suit short replacements, while a five-foot option provides more material for a longer run. The corrugated product is supplied as two six-inch sections for compact connections. Measure the required path and account for routing and bends before choosing; extra length does not ensure a correct fit.
Which fuel compatibility details matter?
Check the exact fuel type, especially if the system uses ethanol blends such as E85. The listed products vary in which fuels they name and in how much technical detail they provide. Select a hose whose stated compatibility matches the fuel used, rather than relying only on the 5/16-inch size.
Should pressure and temperature ratings guide the choice?
Compare the listed working pressure and temperature range with the requirements for your specific application. A burst-pressure figure is not the same as a working-pressure rating. Some options provide both figures; others do not list them in the supplied details. Do not treat missing specifications as equivalent to a confirmed rating.
What dimensions should you verify before ordering?
Confirm inner diameter, outer diameter, and length. The 5/16-inch measurement refers to inner diameter in these listings, while outer diameter can affect connection fit and available clearance. Check the pump and fitting requirements, and follow appropriate repair procedures when handling fuel-system components.
Frequently Asked Questions
What does 5/16 inch describe on fuel hose listings?
For these products, 5/16 inch describes the hose’s inner diameter. Check the listed outer diameter as well when confirming fit.
Can 5/16-inch submersible fuel hose be used with E85?
Several products here explicitly list E85 compatibility. Confirm that the specific hose you choose names E85 or otherwise meets the fuel-system requirements.
Is SAE 30R10 relevant for hose inside a fuel tank?
SAE J30R10 is identified in the product details as a specification for in-tank fuel service. Check the hose listing and application requirements before installation.
Is a burst-pressure rating the same as working pressure?
No. Burst pressure and working pressure are separate specifications. Use the working-pressure figure when comparing normal operating requirements.
