The Multiquip 16015ZE1811 is a genuine OEM Float Chamber Set designed for a wide range of Multiquip-portfolio equipment including portable generators, concrete mixers, diaphragm pumps, centrifugal pumps, trash pumps, and walk-behind power trowels. This is a direct OEM replacement sourced through the Multiquip parts program, ensuring the correct fit for models such as GA-2.5H, GAC2.2H, QP2H, QP303H, QP-202TH, CA4HM, MC-42S, CMS-4S, MQD2H, and related series. Because the float chamber is a precision carburetor component, using the correct OEM part is critical to maintaining proper fuel metering and consistent engine performance across all compatible equipment. DHS Equipment stocks the 16015ZE1811 to keep your machines running with the right part the first time.
Key Features
- Genuine OEM Carburetor Component — Manufactured to the exact dimensional and material tolerances required for correct float height and fuel metering on Honda-powered Multiquip equipment.
- Drop-In Carburetor Fit — Mounts directly into the carburetor body with no modification, replacing the existing float chamber housing and sealing surfaces as originally designed.
- Broad Multiquip Fleet Coverage — Fits GA-2.5H, GAC2.2H, QP2H, QP303H, QP205SH, QP-202TH, CA4HM, CA4.4HM, MC-42S, CMS-4S, MQD2H, D306, SDP-2, SDP-3, CP-20H, QP-204H, and additional models across the Multiquip portfolio.
- Restores Correct Fuel Level Control — A properly functioning float chamber maintains the fuel level inside the carburetor bowl; a cracked, warped, or leaking chamber causes hard starting, rough idling, and fuel leaks that can halt operations entirely.
- Fuel System Integrity — The OEM float chamber provides the correct sealing surface and material resistance to gasoline and ethanol-blended fuels, reducing the risk of fuel seepage at the carburetor bowl joint.
The float chamber is the lower housing of the carburetor bowl that holds a controlled reserve of fuel and supports the float mechanism. As the engine draws fuel, the float rises and falls with the fuel level, opening and closing the needle valve to maintain the correct fuel height for consistent air-fuel mixture delivery. When the float chamber cracks, warps, or develops a damaged sealing surface, the carburetor can no longer maintain the correct fuel level — leading to flooding, lean running, fuel leaks, or an engine that refuses to start. Replacing a worn or damaged float chamber with the correct OEM part restores proper carburetor function and prevents fuel system issues from cascading into more serious engine problems.
