The Multiquip 366220040 Fuel Tank Cap Assembly is a genuine OEM replacement designed for the MTX-85DY rammer. Sourced directly from Multiquip, this cap assembly delivers an exact fit to the fuel tank on MTX-85DY units, ensuring a proper seal and correct fuel system operation. If your existing cap is cracked, missing, or no longer sealing correctly, the part is the authorized replacement to restore it to spec.
Key Features
- Genuine OEM Seal Integrity — Manufactured to Multiquip's original design tolerances, ensuring the cap seats and seals against the fuel tank opening exactly as intended.
- Direct-Fit Replacement — Engineered specifically for the MTX-85DY rammer fuel tank; installs in place of the original cap with no modification needed to the tank neck or venting system.
- MTX-85DY Fitment Confirmed — Verified compatible with the MTX-85DY series rammer, so you can order with confidence knowing this is the correct part for your machine.
- Fuel System Protection — A properly sealing fuel cap prevents contamination, fuel evaporation, and pressure irregularities that can cause hard-starting or carburetor fouling on small-engine rammers.
- Fuel Safety Compliance — A failed or missing fuel cap creates a spill and fire hazard on active worksites; replacing it promptly with a genuine OEM cap maintains safe fuel system integrity.
The fuel tank cap assembly seals the fuel tank opening on the MTX-85DY rammer, keeping fuel contained and preventing dirt, debris, and moisture from entering the tank. A functioning cap also maintains the correct venting balance the fuel system relies on for consistent fuel delivery to the carburetor. When this cap cracks, warps, or loses its sealing gasket, the result is fuel leakage, contamination risk, and potential fuel starvation that interrupts compaction work.
