The Multiquip 18166 Fuel Cap 4 Inch Diameter is a genuine OEM replacement designed for WBH-16 series Whiteman hydraulic power buggies, including the WBH-16, WBH-16E, WBH-16F, WBH-16EF, WBH-16EAWD, and WBH-16EAWDF. As a factory-sourced component, it is manufactured to the same standards as the original cap installed at the point of production, ensuring a correct fit on the 4-inch diameter fuel filler neck. This part is stocked by DHS Equipment and is available for fast dispatch to keep your equipment running without unnecessary delays.
Key Features
- OEM Seal Integrity — Manufactured to the original specification, this cap provides a consistent, airtight closure on the 4-inch diameter fuel filler neck, preventing evaporation and contamination.
- Direct-Fit Replacement — Engineered to thread or seat identically to the original cap, installation requires only hand tools and no rework to the filler neck or surrounding components.
- Broad WBH-16 Series Coverage — Confirmed fitment across WBH-16, WBH-16E, WBH-16F, WBH-16EF, WBH-16EAWD, and WBH-16EAWDF hydraulic power buggy variants.
- Fuel System Protection — A properly sealing fuel cap keeps debris, moisture, and dust out of the tank, protecting the fuel system and maintaining clean fuel delivery to the engine.
- Fuel Containment Safety — A compromised or missing fuel cap creates a spill and fire hazard on active job sites; replacing a worn cap immediately restores correct fuel containment.
The fuel cap seals the opening of the fuel tank, preventing fuel from spilling during operation and keeping contaminants out of the fuel supply. On power buggies like the WBH-16 series, which operate across uneven terrain and active pour sites, a secure cap is critical to both safe operation and engine health. When a fuel cap becomes cracked, stripped, or lost, the tank is left exposed to dirt and moisture that can clog fuel system components and lead to engine performance issues.
