smseace Fuel Line Hose Kit 25pcs — 3.3 ft NBR Rubber Hoses (5 Sizes) with 20 Spring Clamps — Oil & Fuel Resistant, Polyester-Braid

smseace 25pcs 3.3Ft fuel line hose kit is a complete set of five inner-diameter NBR rubber hoses plus 20 spring clamps designed to replace and repair fuel lines on small engines and automotive systems.

This kit gathers five commonly used inner diameters—3/16", 1/4", 5/16", 3/8" and 1/2"—each supplied in 3.3 ft (1 m) lengths and reinforced with a polyester braided layer. Built for fuel delivery tasks, the hoses resist oil, fuel and abrasion while the included 65Mn spring-steel clamps secure fittings under vibration and temperature changes. The result is a versatile maintenance pack for lawn mowers, ATVs, motorcycles, outboard motors and many small-engine applications.

What sizes are included and how do they fit common engines?

The kit contains five inner-diameter options to match a wide range of fuel fittings. Each size is supplied as a 3.3 ft length so you can cut to fit and keep leftovers for future repairs.

• 3/16" ID (4.8 mm ID, 11 mm OD) — good for small carburetor return or vacuum lines
• 1/4" ID (6 mm ID, 12 mm OD) — common on older lawn mower and small motors
• 5/16" ID (8 mm ID, 15 mm OD) — fits many carburetor and primer-bulb connections
• 3/8" ID (10 mm ID, 17 mm OD) — suitable for larger fuel feed lines on ATVs and generators
• 1/2" ID (13 mm ID, 20 mm OD) — for bigger engines and inline filters

What materials and construction give these hoses durability?

Each hose is a three-layer NBR (nitrile butadiene rubber) assembly with a polyester braided middle layer. NBR provides oil and fuel resistance; the braided reinforcement improves burst and abrasion resistance while maintaining flexibility.

• Inner NBR tube resists gasoline and diesel exposure
• Polyester braided layer adds tensile strength and prevents kinking
• Outer rubber jacket resists wear and weathering during outdoor use

How do the included hose clamps perform and install?

The kit includes twenty 65Mn spring-steel clamps that use spring tension to hold hoses to barbs or fittings. Spring clamps accommodate thermal expansion and vibration better than rigid screw clamps in many small-engine settings, and they’re quick to install with pliers.

• 65Mn spring-steel resists fatigue for repeated compression cycles
• Push-on installation with pliers — no screwing required
• Multiple clamps allow secure fastening at both ends and spare clamps for future use

Which fuels and machines are these hoses suitable for?

These hoses are formulated for liquid fuels and common engine oils; they are intended for fuel delivery and related fittings on small engines. They are not intended for pressurized fuel injection systems or applications requiring specific regulatory approvals.

• Compatible with gasoline, diesel and many engine oils
• Ideal for lawn mowers, snow blowers, motorcycles, ATVs, boats and generators
• Not recommended for high-pressure injection systems or corrosive chemicals

Who is this for: The smseace 25-piece fuel line kit suits DIYers, mechanics and fleet owners who need a range of replacement fuel lines and clamps for small engines. If you maintain outdoor power equipment, restore vintage bikes, or keep a boat or ATV running, this kit gives multiple diameters and spare clamps to complete common repairs quickly and keep spare hose on hand.
