The Multiquip EM16400 is a genuine OEM Fuel Tank Cap with Gasket designed for GAW180HE series welders, GA series gasoline powered generators, WM series Whiteman mixers, and EM series Essick mixers. As a direct OEM replacement, this cap and gasket assembly meets original design specifications, ensuring a proper seal on the fuel tank. Verified fitment includes models GAW180HE, GAW180HE1, GAW180HEA, GA3.6HR, GA6HEB, GA6HB, GA3.6HA, GA3.6HZ, GA6HZ, WM90PLF, WM90SLF, WM70PLF, WM70SLF, WM63SLF, EM90SLF, and EM70SLF.
Key Features
- OEM Sealing Integrity — Manufactured to original spec with a matched gasket that maintains a fuel-tight seal, preventing leaks and fuel evaporation during operation.
- Drop-In Fitment — Threads directly onto the original fuel tank opening with no modification; the integrated gasket compresses correctly against the tank neck for a flush, secure fit.
- Broad Model Coverage — Confirmed for GAW180HE series welders, GA3.6 and GA6 gasoline generators, WM70/WM90 Whiteman mixers, WM63SLF, and EM70/EM90 Essick mixers.
- Fuel System Protection — A properly sealed cap prevents debris, moisture, and contaminants from entering the fuel tank, protecting carburetors and fuel system components downstream.
- Fuel Safety Compliance — A correctly sealing fuel cap is essential on gasoline-powered equipment to prevent vapor release and fuel spillage — a genuine OEM cap ensures the closure meets original safety design intent.
The fuel tank cap with gasket seals the fuel tank opening on gasoline-powered equipment, keeping the fuel supply clean and contained during operation, transport, and storage. The gasket creates a compression seal between the cap and the tank neck, preventing fuel from sloshing out and stopping outside contaminants from entering. When the cap becomes cracked, the gasket deteriorates, or the threads strip, the seal fails — leading to fuel odor, spillage, contamination of the fuel supply, and potential carburetor fouling across the wide range of welders, generators, and mixers this part serves.
