sanbaiyi Fuel Tank Assembly for John Deere L100 Series — GY21876/GY21102/GY20894 Kit with Hardware

This sanbaiyi fuel tank assembly (GY21876 / GY21102 / GY20894) replaces worn or damaged tanks on a wide range of John Deere, Scotts and Sabre L100‑series lawn tractors.

If your tractor is leaking fuel, has a cracked reservoir, or you need a complete replacement kit, this sanbaiyi assembly delivers the tank and all mounting hardware needed to restore reliable fuel storage and routing. The package includes the tank plus clamps, straps, brackets, connectors and an oil/fuel line so you won’t need to source additional small parts for a typical swap. It fits many models in John Deere’s 100 series and related Scotts/Sabre machines — but pay attention to deck size exclusions before ordering.

Which machines will this fuel tank fit?

This kit lists multiple compatible model numbers across John Deere, Scotts and Sabre tractors. Check your model against the fit list and avoid models that use a 54‑inch deck, which are not supported by this part. When in doubt, compare the OEM part numbers GY21876, GY21102 or GY20894 (704665) to your machine’s parts manual.

• Compatible John Deere L models: L100, L105, L107, L108, L110, L111, L118, L120, L130
• 100 Series tractors and related: 102, 105, 115, 125, 135, 145, 155C, 190C
• LA / D / X series and Sabre/Scotts models listed in the product specs
• Not compatible with models that use a 54‑inch deck

What comes in the box and what will I need to finish the job?

The delivered kit is intended to be nearly plug‑and‑play for common replacements: it contains the fuel tank and the fasteners and fittings typically removed during a swap. You may still want basic hand tools, a safe fuel drain container, and optionally expandable foam to secure the tank after installation.

• Included: fuel tank assembly, 1 pipe clamp, 4 straps, 1 oil pipe, black and white brackets, 1 screw, 2 connectors
• Tools recommended: screwdrivers, socket set, pliers, fuel catch pan
• Optional: expandable foam filler to cushion the tank and reduce vibration
• Tip: check online installation videos to shorten installation time

How difficult is installation and how long will it take?

Installation difficulty ranges from moderate to straightforward for hands‑on DIYers familiar with small tractors. Drain the old fuel safely and follow the mounting points and hose routing from the old tank as a guide. Many users report that clear step‑by‑step video tutorials reduce the job from several hours to roughly thirty minutes once familiar with the process.

• Remove battery and drain fuel before starting for safety
• Follow bracket alignment and hose connector orientation from the original tank
• Secure with included straps and clamps, then test for leaks before regular use
• Allow time for foam filler to cure if you use it for vibration damping

Who is this for? This sanbaiyi replacement fuel tank is designed for owners, repair shops, and farm maintenance personnel who need a full replacement kit for John Deere L100‑series, select 100 Series tractors, and compatible Scotts/Sabre machines. It’s ideal if you want a complete hardware package instead of hunting down individual parts, and for those comfortable performing routine tractor maintenance.
