Stens Clear PVC Fuel Line 1/4" ID x 25' — 7/16" OD, Flexible Oil-Resistant Hose for Small Engines

The Stens 115-121 is a 25-foot clear PVC fuel line with a 1/4" inner diameter and 7/16" outer diameter designed for reliable fuel delivery on small engines.

This clear PVC fuel hose is made for mechanics, landscapers, and hobbyists who need a visible, flexible line that resists oil, chemicals, and routine wear. It’s manufactured to fit common small-engine fuel fittings and gives you long reach for repairs or replacement runs. Note: it is not compatible with fuels containing more than 10% ethanol.

How will this hose improve servicing small engines?

Because the tubing is clear, you can quickly confirm fuel flow and spot air, debris, or contamination without disassembly. Its flexibility lets you route the hose in tight spaces, while the material resists typical shop chemicals and oils, so it holds up during regular maintenance.

• Clear PVC for visible fuel flow and quick diagnostics
• Flexible construction for routing through confined engine bays
• Chemical- and oil-resistant surface for longer service life
• Universal dimensions for common small-engine fittings

Will this fuel line fit my mower, trimmer, or small tractor?

The Stens 115-121 uses a 1/4" inner diameter, a 7/16" outer diameter, and comes in a 25' roll — dimensions chosen to match typical small-engine fuel and gravity-feed applications. It’s intended as a general-use replacement hose for many lawn and garden machines, though you should check your equipment’s required inner diameter before installation.

• 1/4" inner diameter for standard fuel fittings
• 7/16" outer diameter for common clamp sizes
• 25-foot length for multiple replacements or long routing runs
• Works with most carbureted small engines and fuel tanks

What fuels and conditions is this tubing suited for?

The tubing resists gasoline, diesel, oil, and many shop chemicals encountered in routine service, making it suitable for everyday small-engine use. It is not rated for fuels that contain over 10% ethanol, so avoid use with E15 or higher blends to prevent premature degradation.

• Compatible with gasoline up to 10% ethanol (E10) and diesel
• Resistant to oil and many common chemicals
• Not recommended for blends above 10% ethanol
• Safe for standard temperature ranges in outdoor equipment

How easy is installation and what accessories help?

The hose’s smooth, pliable PVC makes cutting and clamping straightforward with basic tools. For a secure, leak-free repair, use the proper-sized clamps and the Stens 750-918 hose removal tool to free old lines without harming fittings.

• Cut cleanly with hose or utility scissors
• Secure with standard small-engine clamps or crimp fittings
• Pair with Stens 750-918 removal tool for safe replacement
• Flexible for quick, low-effort installs in tight areas

Who this is for: The Stens 115-121 fuel line is intended for maintenance professionals, backyard mechanics, and property owners who service lawnmowers, trimmers, generators, and other small engines. If you need a visible, chemical-resistant replacement hose for routine repairs or spares — and you use fuels no greater than 10% ethanol — this roll gives enough length for multiple fixes and can be trimmed to fit a variety of machines.
