ZTTM Nylon Fuel Line 25 ft 5/16" OD (1/4" ID) — flexible, fuel-resistant tubing for small engines

ZTTM's 25-foot 5/16" OD (1/4" ID) nylon fuel line is a flexible, fuel-resistant tubing designed to replace or extend fuel and fluid runs on small engines, vehicles, and equipment.

This nylon fuel line (model 800-074) provides a straightforward solution when you need a durable, easy-to-route replacement for short fuel runs. Made from fuel-compatible nylon, the tube balances pliability for bends and routing with chemical resistance to gasoline, diesel, and many fluids. It comes as a single 25-foot coil that you can cut to length, making it useful for repairs, custom routing, or bundling multiple sections for larger projects.

How does this fuel line stand up to fuel and oil exposure?

The ZTTM nylon material is formulated to resist degradation when in contact with common fuels and engine oils under typical operating conditions. It won't soften or collapse quickly in those environments, giving you reliable short-term service for fuel delivery or fluid lines.

• Material: fuel-compatible nylon designed for gasoline and diesel contact
• Thickness: approximately 1mm wall for structural support
• Resists ordinary oil and fuel exposure in engine bays and undercarriages

Will this tubing fit my engine or equipment fittings?

The outer diameter is about 5/16" (8mm) with an inner diameter near 1/4" (6mm), which matches many common small-engine and inline fittings. Because it is flexible, it can be trimmed to length and pushed onto barbed fittings or secured with clamps for a tight seal.

• Outer diameter: ~5/16" (8mm); inner diameter: ~1/4" (6mm)
• Compatible with standard 1/4" fuel nipples and barbs when clamped
• Can be cut to fit custom runs or multiple repair points

How easy is it to install and route the tubing?

The nylon line is flexible enough to bend around tight spaces while remaining stiff enough to push onto fittings without collapsing. Its 25-foot length gives you enough material to route long runs or to keep spare line for future repairs.

• Flexible for routing through engine bays and under chassis
• Can be bent by hand—no special tools needed for most installations
• Use hose clamps or crimp-style clamps for secure connections

How much tubing do I get and how should I prepare it for use?

You receive a single continuous 25-foot coil that you can cut to needed lengths. Before installation, measure required lengths, deburr cut ends, and dry-fit with clamps to ensure proper seating and leak-free joints.

• Total length: 25 feet, suitable for multiple short runs or one long run
• Cut-to-fit: supports customization and multiple replacement sections
• Prep steps: measure, cut cleanly, check fit, secure with clamps

Who is this for: DIY mechanics, small-engine technicians, landscapers, ATV and motorcycle owners, and anyone needing a cost-effective replacement fuel or fluid line. If you work on lawnmowers, generators, compact tractors, or other equipment that uses 1/4" ID fuel tubing, this ZTTM nylon line offers a simple, adaptable solution. Always confirm size compatibility and use appropriate clamps; this product is for tubing replacement and routing—not for high-pressure fuel injection systems.
