Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original design specifications for the Honda GX100UKRBF fuel pump assembly, ensuring correct material grade and dimensional accuracy.
• Direct Drop-In Replacement — Mounts directly to the GX100UKRBF fuel pump housing with the original bolt pattern and sealing surface, eliminating fitment uncertainty.
• Confirmed Rammer Fitment — Compatible with MTX50HD, MTX60HD, MTX70HD, and MTX80HDR rammers, covering a wide range of the MTX heavy-duty compaction line.
• Protects Fuel Pump Integrity — Seals and shields the internal diaphragm and pump components from debris and contamination, maintaining consistent fuel delivery to the engine under demanding compaction conditions.
• Fuel System Safety — A cracked or missing pump cover can expose the fuel pump diaphragm to air leaks and debris ingestion, leading to hard-start conditions or fuel delivery failure; replacing it promptly keeps the fuel system sealed and operating safely.

The pump cover on a Honda GX100UKRBF engine encloses and protects the fuel pump diaphragm assembly, which is responsible for drawing fuel from the tank and delivering it to the carburetor at the correct pressure and flow rate. Without a properly sealed cover, the diaphragm is vulnerable to contamination, physical damage, and vacuum leaks that disrupt fuel delivery and cause the engine to run lean, surge, or fail to start. A worn, cracked, or missing pump cover should be replaced promptly to maintain consistent engine performance in your MTX rammer.
