Multiquip EM234 Fuel Filter

The Multiquip EM234 Fuel Filter is a genuine OEM replacement designed for a wide range of Multiquip and Whiteman equipment, including centrifugal pumps, ride-on power trowels, walk-behind trowels, concrete vibrators, and rammers such as the MT60H2. As a factory-authorized OEM component, the EM234 is built to the exact specification of the original part it replaces, ensuring correct flow rate, thread compatibility, and filtration rating across all covered models. Compatible equipment includes the QP402B, HHN31V, HHN34TVD, STX6H, STXD6i, HTX6H, HTXD6i, CA4HC, CA4HM, CA5BC, JWN24HTCSL, and more — making this a high-volume service part used across multiple Multiquip product families. Stocking the EM234 means faster turnaround on routine maintenance and fewer delays during busy project schedules.

Key Features

• OEM Filtration Specification — Manufactured to the original filtration rating and flow capacity, protecting fuel system components from particulate contamination across all listed equipment types.
• Direct-Fit Installation — Matches the original filter's thread pitch and housing dimensions, so installation follows the same procedure as the factory service manual with no adaptation needed.
• Broad Cross-Family Compatibility — A single part number covering centrifugal pumps (QP402B), ride-on trowels (HHN31V, STX6H, HTX6H, STXD6i), walk-behind trowels (CA4HC, CA4HM, CA5BC), vibrators (G55H, P-Series), and rammers (MT60H2).
• Fuel System Protection — A clean, correctly flowing fuel filter keeps engine RPM stable and prevents injector or carburetor fouling — a failed or clogged filter is a leading cause of hard starting and rough running on these machines.
• Genuine OEM Confidence — Sourced directly from Multiquip as an authorized OEM part, so part number EM234 matches exactly what was installed at the factory — no guesswork on specification or fitment.

A fuel filter's job is to catch dirt, debris, and water contamination before they reach the carburetor or fuel injectors. On equipment like power trowels, rammers, and pumps — which often operate in dusty, muddy, or wet environments — keeping the fuel supply clean is critical to consistent engine performance. When a fuel filter becomes clogged or degraded, the engine may starve for fuel, run erratically, lose power under load, or fail to start altogether. Replacing the EM234 on schedule is one of the simplest and most cost-effective steps in a routine maintenance program for any of the covered Multiquip machines.
