MOTO1988 Fuel Tank Valve Petcock 3‑Way Replacement for Polaris — Knob & Nut Included, OEM Fit

MOTO1988's 3-way fuel tank valve petcock is a direct-fit replacement kit (valve, knob, nut) designed to restore reliable fuel flow on compatible Polaris ATVs and utility units.

If your Polaris has a leaking, stiff, or non‑functioning fuel shutoff, this OEM‑style petcock assembly replaces part number 7052161 (replacement 5432559) and ships with the knob and retaining nut required for installation. The kit is intended as a straightforward mechanical replacement for many late‑1990s through mid‑2000s Polaris Sportsman, Magnum, Trail Boss, Xplorer, Xpedition, Ranger, Big Boss, ATP, PTV and related models — see model compatibility below. Use it to stop drips, regain clear on/off/reserve selection, and avoid fuel starvation from a failed valve.

Which Polaris models will this petcock fit?

This fuel valve matches numerous Polaris machines from 1997–2009 across Sportsman, Magnum, Trail Boss, Xplorer, Xpedition, Ranger, Big Boss, ATP, PTV and other lines. Fit depends on year and specific model subvariant, so confirm your OEM number or compare with photos before ordering.

• Replaces manufacturer part 7052161 and aftermarket 5432559
• Fits Sportsman 400/500/600/700 variants (selected years)
• Compatible with Magnum, Trail Boss, Xplorer/Xpedition and select Ranger/Big Boss/ATP/PTV models
• Kit includes valve, knob and mounting nut for a complete swap

How easy is installation for a home mechanic?

Installation is typically simple for anyone comfortable with basic hand tools and removing a fuel line. The job usually takes 20–40 minutes: drain a small amount of fuel or work with low tank level, loosen the old nut, remove the valve and hoses, then fit the new assembly and tighten the supplied nut.

• Hand tools required: wrench, pliers, screwdriver and optional fuel catch container
• Drain or position tank to avoid fuel spillage during removal
• Replace old hose clamps if brittle or rusted for a secure seal
• Test for leaks and proper on/reserve/off positions after installation

What are the parts and materials included in the package?

The kit is shipped with the complete petcock valve body, a plastic or molded replacement knob, and the retaining nut required to secure the valve to the fuel tank. Materials are selected to match the original fit and function for the covered Polaris models.

• Fuel valve petcock ×1 — complete body assembly
• Replacement knob ×1 — user control for on/off/reserve positions
• Mounting nut ×1 — secures valve through tank mounting hole
• Manufactured to match OEM dimensions for direct fit

Will this fix leaks or restore proper reserve function?

Yes — when failure is limited to the petcock, exchanging the valve typically stops seepage and restores proper fuel selection between on and reserve. If leaks stem from harmed tank threads, damaged hoses, or internal tank corrosion, additional repair may be necessary.

• Stops valve‑originated drips and seepage
• Restores selectable fuel flow (on/reserve/off) when valve is the issue
• Inspect tank mounting threads and fuel hoses during replacement

Who this is for: This MOTO1988 petcock kit is aimed at Polaris owners and DIY mechanics who need a direct replacement for a failing fuel valve on older Sportsman, Magnum, Trail Boss, Xplorer/Xpedition, Ranger, Big Boss, ATP or PTV machines. Buy it if you want an OEM‑style swap with the knob and nut included so you can complete the repair in one visit, or if you manage maintenance for fleets of vintage Polaris ATVs where original parts are preferred for fit and function.
