Meonum 5/16" SAE 30R10 Submersible Fuel Hose Kit, 2x1ft for E85/Ethanol — 300 PSI, Includes 4 Stainless Clamps

Meonum's 5/16" SAE 30R10 submersible fuel hose kit is a two-piece, in-tank ready fuel line set engineered to resist E85 and other aggressive fuels while delivering up to 300 PSI working pressure.

This compact kit contains two one-foot sections of 5/16" (8mm) internal diameter hose and four stainless-steel clamps, built for applications that demand submerged compatibility and chemical resistance. The hose meets SAE J30 R10 expectations for in-tank use and is constructed from high-grade synthetic material that resists swelling, softening, and deterioration when exposed to ethanol blends, gasoline, or diesel. With a 14mm outer diameter and tight manufacturing tolerances, these lines are sized for reliable connections on common fuel pump and sender barbs.

How does this hose handle ethanol fuels like E85?

The Meonum hose is formulated to tolerate ethanol-blended fuels without losing flexibility or integrity. It resists the common failures—softening, cracking, or swelling—that ordinary hoses experience in corrosive fuel atmospheres. That makes it a practical choice for modern and performance engines that run higher ethanol mixes.

• SAE-30R10 compatible material for submerged ethanol exposure
• Rated to withstand constant immersion without softening
• Wide operating temperature range for cold and hot conditions

What pressure ratings and safety margins does this kit provide?

The hose supports a continuous working pressure of 300 PSI and a maximum burst capability up to 1200 PSI, giving a strong safety margin for fuel injection systems and high-demand pumps. The included stainless clamps provide consistent, 360-degree compression for leak-free joins under vibration and pressure spikes. These ratings make the set suited for many automotive and marine injection tasks where higher pressures are present.

• 300 PSI working pressure for routine system demands
• 1200 PSI burst rating for extreme event protection
• Four heavy-duty stainless clamps (13–19mm range) for secure seals

Will these hoses fit my in-tank pump or fuel-return setup?

With a 5/16" (8mm) internal diameter and 14mm outer diameter, these hoses are sized to work with many common fuel pump barbs and return lines. The one-foot length of each section gives flexibility for replacing feed and return lines or installing a spare line inside the tank. Measure your existing hose ID and barb size to confirm compatibility before installation.

• Internal diameter: 5/16" (8mm); outer diameter: 14mm ±0.6mm
• Two 1-foot sections permit feed and return or spare configuration
• Clamps fit 13–19mm hose fittings for secure attachment

How easy is installation and what hardware is included?

The kit arrives ready to install: two pre-cut 1-foot hoses and four precision stainless clamps remove the need to source additional parts. The clamps are engineered to tighten evenly around the fitting to minimize leaks and withstand vibration common in engines and marine environments. Basic hand tools are all that’s needed for a clean, fast swap.

• Two 1-foot SAE 30R10 hoses for immediate replacement
• Four heavy-duty stainless-steel clamps for even 360° sealing
• Installable with common hand tools in minutes

Who is this for: Mechanics, restoration specialists, boat owners, and DIY enthusiasts who need a reliable submersible fuel line that stands up to ethanol blends and high-pressure injection systems. If you want a compact, all-in-one replacement kit that reduces the risk of in-tank hose failure and includes clamps sized for secure fittings, this Meonum hose set is designed to meet those needs without extra parts hunting.
