YOXUFA Metal Fuel Tank Cap & Complete Fuel Kit for 50–125cc ATVs — Heavy‑Duty Replacement with Breather

YOXUFA Metal Gas Fuel Tank Cap and complete fuel kit replaces worn caps and fuel components on many 50–125cc Chinese ATVs and lawn machines, restoring a secure seal and reliable fuel flow.

This metal gas tank cap and accompanying fuel kit from YOXUFA is built as a direct, heavy-duty replacement for small-displacement ATVs and similar machines. The assembly combines a high-strength metal cap with essential fuel hardware so you can replace a damaged cap, clogged filter, cracked hose or failing petcock in one service. It’s designed for broad fitment across common Chinese models to make repair faster and reduce downtime.

Which ATVs and machines will this cap and kit work with?

The kit is engineered to match many 50cc to 125cc Chinese-made quads and small utility machines, including popular TaoTao and Coolster models. Fit depends on tank neck diameter and mounting points, so checking measurements before purchase avoids surprises. This product suits both single-replacement needs (cap only) and full fuel line/service refreshes.

• Compatibility range: 50cc, 70cc, 90cc, 110cc, 125cc models
• Works with brands like TaoTao, Coolster, Buyang, Sunl, PeaceSport, Kazuma, Roketa
• Also fits some lawnmowers and light utility engines using similar fittings
• Confirm tank neck size and mounting style prior to installation

What components are included and why they matter?

The package supplies a complete set of parts to restore a basic fuel system: metal cap, breather cap, fuel filter, fuel line, clips, and a petcock (fuel pump). Replacing the whole set at once avoids mismatched ages of parts and reduces the chance of leaks or poor fuel delivery after service. The metal construction of the main cap offers improved durability compared with brittle plastic originals.

• 1 x metal gas tank (main tank) for compatible ATVs
• 1 x metal gas tank cap with breather valve for venting
• 1 x inline fuel filter to protect carburetors and injectors
• 1 x fuel line with 4 retaining clips and 1 petcock (fuel valve)

How durable and reliable is the YOXUFA metal cap?

The cap is made from high-strength metal designed to resist cracking and provide a better long-term seal than many OEM plastic caps. Quality control checks target dimensional standards to ensure the cap seats correctly and that the breather operates as intended. Regular inspection and correct installation will help maintain fuel-system integrity.

• High-strength metal body for impact and wear resistance
• Precision fit targets OEM-standard dimensions for reliable sealing
• Breather cap included to control tank pressure and venting
• Replaceable inline filter reduces contamination risk to engine

How hard is it to install and what should I check first?

Installation is straightforward for anyone with basic mechanical skills and common tools: drain any fuel remaining, remove the old cap and petcock, then fit the new components in reverse order. Verify hose inner diameter and clip placement to prevent leaks, and test the petcock for correct on/off positions before returning the machine to service. If uncertain, consult a mechanic or the vehicle’s service manual.

• Drain fuel and relieve pressure before starting
• Compare neck diameter and hose size to ensure fitment
• Use supplied clips and tighten securely to prevent leaks
• Check petcock operation and filter orientation before use

Who is this for: This YOXUFA kit targets owners of small-displacement ATVs, go-karts, and lawn equipment that use common Chinese fuel fittings and need a dependable replacement cap and service parts. It’s ideal for DIY mechanics who want to replace multiple aging fuel components in one purchase, fleet managers maintaining several machines, and anyone seeking a more durable metal cap alternative to brittle OEM plastic.
