Neeseelily Fuel Gauge Gas Cap AM39206 — Compatible John Deere 300/400 Series, Sight Gauge & Threaded Seal

Neeseelily AM39206 is an aftermarket fuel-gauge gas cap that replaces OEM caps on select John Deere, Dixie Chopper, Toro, Murray and Honda lawn and compact tractors.

If your tractor’s original gas cap gauge is cracked, leaking, or no longer giving reliable fuel-level readings, this Neeseelily replacement cap restores a visible gauge and a secure seal. Designed as a direct-fit aftermarket part, it is compatible with multiple part numbers so you can swap it in quickly without modifying the fuel tank or sender. The cap combines a molded plastic body with a built-in sight gauge so you can check fuel levels at a glance while keeping contaminants out.
