Traxxas 3147X Fuel Line: 58-Pack for Traxxas Systems

The Traxxas 3147X fuel line set provides a compact source of fuel tubing for models operating within Traxxas ecosystems. The kit emphasizes official compatibility, with two feet of line and a larger 610mm segment included. This option is suited for hobbyists prioritizing genuine Traxxas parts to ensure seamless carburetor delivery and fitment in matching systems. Its simple supply helps maintain consistent fuel flow, reducing the risk of collapse or leakage near the fuel tank area when fitted to compatible engines.
Key considerations include ensuring you are using genuine Traxxas components for optimal performance and avoiding model-specific fit issues. The material appears to be standard silicone for small-scale RC applications, contributing to flexibility while withstanding common operating temperatures. Installation is straightforward, though verify the line diameter against your carburetor fittings to prevent leaks or improper seating.
ShareGoo 2 Meters Silicone Fuel Line Set

The ShareGoo kit provides two long silicone tubes, one 2mm inner diameter and one 3mm inner diameter, each with a 5mm outer diameter. The total length is 4 meters (2 meters per tube), offering flexibility for multiple projects or spare usage. The tubes are described as silicone-based and suitable for nitro glow fuel, with easy installation and durability highlighted. This option is attractive for hobbyists needing reliable silicone lines across several RC platforms or for experiments with different carburetor fittings.
When selecting this option, check the outer diameter compatibility with your existing fittings and ensure the inner diameter accommodates your nitro fuel line specs. Silicone tubes typically handle temperature excursions well but can be prone to kinking if bent sharply. The dual-diameter approach offers versatility for varied carburetor inlet sizes and tank fittings on multi-brand models.
SING F LTD 2m Clear Silicone RC Fuel Line

The SING F LTD option focuses on a 2m length of clear silicone fuel line with a 2.5mm inner diameter and 5.5mm outer diameter. This configuration is typical for nitro engine models, where visibility of fuel status inside the line can be advantageous for maintenance checks. Silicone provides flexibility, light weight, and reliable performance for nitro engines, where heat and vibration are factors. The product emphasizes suitability for nitro models and promises easy handling during installation.
Consider compatibility with your engine’s carb inlet and fuel tank fittings. Clear silicone hoses allow quick visual inspection for cracks or fuel residues, which can be beneficial for ongoing maintenance. Ensure the line’s temperature tolerance aligns with your model’s operating environment to prevent hardening or softening over time.
ATOPRC Large Scale Fuel Line Kit with Clips and Fittings

This high-flow fuel line kit targets large-scale RC cars and other big models. It includes six clips and two fittings to simplify installation and promote stable fuel delivery to the carburetor. The introductory kit design aims to reduce line compression from the fuel tank grommet, helping prevent flow restrictions during high-demand engine operation. The reinforced plastic fittings are touted to resist kinking and collapsing, which is critical for maintaining consistent fuel pressure in performance-first builds.
When evaluating, consider the scale and engine demand of your RC model. A high-flow design supports high-powered gas engines, but ensure the fittings match your carburetor size and fuel tank outlets. The included clips help with secure routing to avoid line damage during operation or rough terrain driving.
Keenso Universal Silicone Fuel Line Tubes

Keenso’s universal silicone fuel line tubes are designed to handle extreme heat and wear, with emphasis on durability and stable performance. The set is marketed as a reliable replacement option for various RC cars, featuring 3x5mm tubes that fit a wide range of gas-powered models. Silicone composition supports flexible routing and resistance to heat, reducing the likelihood of cracking under stress or during high-temperature operation. This option is suitable for hobbyists seeking a versatile, cross-brand replacement line.
As with other universal lines, confirm the inner diameter with your carburetor inlet and check the outer diameter against body clearance and tank grommets. Availability of multiple lengths and consistent ID/OD sizing helps in standardizing a few builds without stock rotation.
Drfeify 1/10 Universal Silicone Fuel Line Tube

The Drfeify option highlights a 1/10 scale universal silicone fuel line tube with a 3x5mm sizing. Constructed from silicone, it is designed to resist heat and wear while maintaining high reliability for model cars. The listing emphasizes broad compatibility with popular 1/10 gasoline RC cars and suggests sturdy practicality for routine maintenance or upgrades. This makes it a practical pick for builders needing a dependable replacement line that can fit several chassis types.
Potential buyers should verify the exact ID/OD requirements for their carburetor or fuel system and ensure compatibility with existing clamps and fittings. Silicone’s durability is advantageous for repeated engine starts and long sessions, while the 3x5mm footprint is common enough to fit many vehicles.
Tnfeeon Thick Fuel Line Tube for RC Cars

Tnfeeon’s thick 3x5mm silicone fuel line offers robust performance for RC cars and toy gasoline vehicles. The product emphasizes compatibility with 1/10 scale models and similar platforms, with emphasis on heat resistance, durability, and reliability. The line’s silicone construction supports flexible routing and a steady fuel supply to the engine, which is important during high-pressure operation or aggressive driving. As with other universal options, confirm the precise internal diameter needed for your carburetor inlet before purchase.
This option can be attractive for builders seeking a resilient line that stands up to repeated flexing and heat. Ensure routing accounts for sharp bends to avoid potential kinking and verify that the line length accommodates your setup without excess slack.
Generic RC Nitro Car Fuel Line: Clear Silicone Hose

The Generic clear silicone hose targets a broad range of RC nitro applications, advertised for 1/8 to 1/12 scale trucks and crawlers. The line is labeled as easy to install and durable, with general silicone composition suitable for glow engine systems. Clarity offers straightforward inspection for cracks or fuel presence along the tube path, which can be useful during maintenance. This option is suitable for hobbyists who want a visible line and a flexible, temperature-tolerant material.
Buying Guide: Key Purchase Considerations
- Size compatibility: Match inner and outer diameters to carburetor fittings, tank nipples, and grommets. A poor fit can cause leaks or fuel starvation.
- Material and temperature tolerance: Silicone is common for nitro and glow engines due to heat resistance and flexibility. Avoid rigid or inelastic tubes in high-vibration models.
- Durability vs. flexibility: Thick walls reduce collapse risk, but overly stiff lines may resist bending in tight chassis spaces. Consider your setup’s routing path.
- Brand vs. universal: Brand-specific lines (e.g., Traxxas) ensure fit to certain models, while universal lines offer cross-brand compatibility. Verify the exact needs of your model before buying.
- Installation ease: Pre-assembled kits with clips and fittings simplify mounting and reduce additional purchases. Check for included hardware.
- Visual inspection: Clear hoses enable quick checks for cracks or fuel leakage. This can help with proactive maintenance.
- Compatibility with fuel type: Some lines are specified for nitro or glow fuels. Confirm that the line is designed for your fuel type to avoid material degradation.
- Maintenance considerations: Regular checks for kinks, cracks, and hardening extend line life. Replacing worn lines can prevent engine starvation or leaks.
The above options cover a range of needs—from brand-tpecific lines to universal silicone tubes. Prospective buyers should assess model scale, engine type, and available mounting space. A balanced selection favors lines with proven heat resistance, reliable fittings, and adequate length for future projects.
