Replacement Fuel Tank Gas Cap with Gauge for Polaris Snowmobiles – Replaces OEM 2520815 – Fits 2008–2021 Models

OVERVIEW

This SPI fuel tank gas cap with integrated gauge restores precise fuel monitoring and leak-resistant sealing for Polaris snowmobiles built with the standard inlet design. Constructed with reinforced materials to withstand extreme cold and trail vibration, the durable cap ensures consistent engine operation while replacing cracked or unreliable factory units. It serves as a direct-screw replacement specifically engineered for Polaris snowmobile platforms.

ENGINEERING & PERFORMANCE

The precision-engineered screw-on threads maintain secure sealing against temperature swings and chassis flex, preventing fuel vapor escape and moisture ingress during steep rides or deep snow conditions. A tough, reinforced outer shell withstands repeated ice impact and heavy vibration, keeping the built-in fuel level gauge continuously readable in sub-zero environments. Designed to replicate original equipment geometry, this cap installs directly onto established Polaris fuel inlets without requiring aftermarket adapters or modified fittings.

The precision-machined threads resist winter temperature swings, keeping vapors and moisture out of the intake while maintaining steady fuel delivery during long trail sessions. Paired with an impact-resistant exterior, the assembly stays secure even after heavy contact with trail debris or packed snow. By perfectly mirroring the original equipment layout, it bolts directly to established Polaris platforms and extends reliable service across every riding season.
