Key Features

• Genuine OEM Fuel System Integrity — Manufactured to the original material and dimensional specification for the sediment bowl assembly, ensuring proper fuel flow filtration and a contaminant-free fuel supply to the engine.
• Direct-Fit Replacement — Engineered to drop into the existing fuel sediment bowl assembly on STX55J6 and STX55Y6 trowels with no rework or additional components needed.
• Confirmed Fitment for STX55 Series — Verified compatible with the STX55J6 and STX55Y6 Whiteman ride-on power trowel models.
• Protects Engine Performance — A functioning sediment bulb traps water and particulates before they reach the carburetor or fuel injection system; a cracked or deteriorated bulb allows contaminants through, leading to rough running or engine damage.
• Fuel System Safety — A properly seated and crack-free sediment bulb prevents fuel leaks at the bowl junction, reducing fire risk on fuel-powered equipment.

The sediment bulb is the transparent or semi-transparent bowl located at the base of the fuel sediment bowl assembly. Its job is to collect water and debris that settle out of the fuel supply before they can reach the engine, allowing the operator to visually inspect fuel quality and drain contaminants as part of routine maintenance. When the bulb cracks, shrinks, or loses its seal, the machine can develop fuel leaks, draw in contaminated fuel, or lose prime — any of which will interrupt trowel operation and risk engine damage.
