Multiquip 91424Z4F802 Fuel Tube 4.5x140 FKM GX120UT3

The Multiquip 91424Z4F802 is a genuine OEM Fuel Tube 4.5x140 FKM GX120UT3 designed for the MVB85H vibratory block plate compactor. As a direct OEM replacement, this fuel tube matches the original factory component exactly, ensuring proper fuel delivery between the tank and engine on GX120UT3-powered equipment. DHS Equipment supplies this part as an authorized Multiquip OEM component, giving you confidence in both fit and part number accuracy. Confirm your model code against MVB85H to verify this is the correct tube before ordering.

Key Features

• FKM Fluoroelastomer Construction — FKM-grade rubber provides superior resistance to fuel degradation and heat, maintaining a secure, leak-free seal over extended service life in high-temperature engine environments.
• Exact OEM Dimensions — Cut to the original 4.5 x 140 mm specification, this tube connects directly to the GX120UT3 (PX2) engine fuel circuit without trimming or adapters.
• Genuine Multiquip OEM Part — Sourced directly through Multiquip's authorized parts network, this component meets the same material and dimensional standards as the tube installed at the factory.
• Fits MVB85H Vibratory Block Compactor — Engineered specifically for MVB85H equipment running the GX120UT3 engine, keeping fuel flow consistent and the compaction cycle uninterrupted.
• Fuel System Integrity — A cracked or degraded fuel tube can cause fuel starvation, rough running, or fuel leaks near a hot engine. Replacing it promptly with the correct OEM part restores safe, stable engine operation.

The fuel tube carries gasoline from the fuel tank to the carburetor on the GX120UT3 engine. It must maintain a continuous, airtight passage — any cracking, softening, or pinching in the tube disrupts fuel flow and starves the engine, causing hard starts, erratic running, or a complete shutdown. FKM compound tubing is specified for this application because standard rubber degrades quickly when exposed to modern fuel blends and engine heat; using the correct OEM replacement ensures the tube holds its shape and seal through full working cycles on the MVB85H.
