This hose is confirmed to fit WTB-16PD, WTB-16, WBH-16 series, WBH-21EF, WBH21EPA, AR14H, AR13HA/HAR, PRO12E53, PRO12E51, and PRO12 equipment.

Key Features
- EPA-Compliant Fuel Line Material — Engineered to meet EPA low-permeation fuel hose standards, keeping your equipment compliant with current emissions regulations.
- Correct 1/4" Diameter, 4 Ft. Length — Pre-cut to the original 4-foot (1.2 m) length and sized to the correct 1/4" inner diameter for a direct, secure connection to OEM fuel fittings.
- Broad Multiquip Fitment — Verified for WTB-16, WBH-16 and WBH-21 series power buggies, AR14H and AR13HA/HAR ride-on rollers, and PRO12 series Essick stationary mixers.
- Fuel Delivery Integrity — A correctly functioning fuel hose maintains steady, leak-free fuel flow to the engine; a cracked or deteriorated hose can cause fuel starvation, rough running, or dangerous fuel leaks.
- Fuel System Safety — Low-permeation construction resists fuel vapor transfer and external degradation, reducing the risk of fuel leaks at the line that can become a fire hazard on the jobsite.
- Genuine Multiquip OEM Part — Carries full OEM traceability under part number 520611, eliminating fitment risk when ordering for multiple machine types across the Multiquip portfolio.
The fuel hose carries gasoline from the tank to the carburetor or fuel inlet, maintaining a sealed, continuous supply under the low pressure typical of small-engine fuel systems. Because the hose is constantly exposed to fuel, heat, and engine vibration, the material must resist swelling, cracking, and permeation over time. When a fuel hose deteriorates, it can collapse internally to restrict flow, leak externally to create a fire hazard, or allow air ingestion that causes hard starting and stalling — making timely replacement critical to safe, reliable machine operation.
