Key Features
- Genuine OEM Diaphragm Construction — Manufactured to the same material and flex specifications as the original, ensuring consistent sealing performance across the full operating pressure range of the 3TNV76 engine system.
- Direct-Fit Replacement — Engineered to match the original mounting configuration and port dimensions of the AR16-2, so installation aligns with the existing assembly without rework.
- Confirmed AR16-2 Fitment — Validated for the Multiquip AR16-2 asphalt ride-on roller; reference part number 11980203100 when ordering to confirm correct application.
- Restores Proper Fuel or Fluid Transfer Function — A failed or cracked diaphragm causes inconsistent flow, rough running, or complete loss of pump function; replacing with an OEM part restores normal operation immediately.
- Fuel System Integrity — A correctly seated diaphragm prevents fuel or fluid bypass, protecting downstream engine components and supporting safe, stable machine operation.
A diaphragm assembly is a flexible membrane component used in fuel pumps or similar fluid-transfer systems to create the pulsing action that moves fuel from the tank to the engine. On the AR16-2's 3TNV76 engine, the diaphragm flexes under vacuum and pressure cycles to draw and discharge fuel in precise volumes. When the diaphragm cracks, hardens, or loses elasticity, fuel delivery becomes erratic or stops entirely — leading to hard starting, rough idle, or a machine that won't run at all. Replacing a worn diaphragm promptly keeps the fuel system operating as designed and prevents further stress on the carburetor or injection components downstream.
