Fuel Gauge Gas Cap for Honda Rancher 350 Rancher 400

JAVIK's Fuel Gauge Gas Cap is a drop-in replacement fuel cap assembly with integrated float gauge designed to fit specific Honda ATV models, providing accurate level readings and a durable, leak-resistant seal.

This replacement unit is engineered to match the original equipment fit and function for Honda Rancher 350 (TRX350 2000–2006), Rancher 400 (TRX400 2004–2007, excluding TRX400EX), and Rubicon 500 (TRX500 2001–2004). It includes the fuel gauge module, the cap, and two mounting bolts, and is built with upgraded anti-aging and anti-corrosion sealing materials to withstand fuel exposure and outdoor conditions. The assembly carries OEM reference 17504-HN5-671 so you can confirm compatibility against your bike's parts list.

How accurate is the fuel level reading compared with the original Honda part?

The gauge uses the same float-and-sensor arrangement as the factory unit to deliver comparable fuel-level indications. The float moves freely across the travel range, and the internal sensor translates that motion into a clear dashboard reading.

• Exact gauge structure mirroring OEM design for consistent performance
• Float calibrated to match stock travel and response
• Plug-and-play installation keeps original wiring and connectors

Will this fuel cap leak or corrode over time?

JAVIK upgraded the sealing materials and corrosion-resistant components to extend service life and reduce the chance of fuel seepage. Proper installation and tightened bolts ensure a secure seal; periodic inspection keeps the gasket performing well in harsh environments.

• Anti-aging gasket materials resist hardening and cracking
• Corrosion-resistant housing and hardware for outdoor durability
• Includes two bolts for a reliable mechanical mount

How simple is the installation and what comes in the package?

Installation is straightforward for mechanically inclined riders: remove the old cap and gauge, fit the replacement assembly, secure the bolts, and reconnect any electrical harness. Most users can complete the swap with basic hand tools in under 30 minutes.

• Package includes one fuel gauge assembly, one cap, and two bolts
• OEM reference 17504-HN5-671 helps verify part match before installation
• No special tools required; standard sockets and screwdrivers are sufficient
