The Genie 88757GT is a genuine OEM LP Lockout Valve with Connector designed for a broad range of Genie telescopic boom lifts, articulating boom lifts, and scissor lifts. As a direct OEM replacement, this valve is built to the same specification as the original unit installed at the factory, ensuring correct operation within the machine's liquid propane fuel system. This part fits models including the S-60, S-65, S-80, S-85, Z-45/25, Z-45/25J IC Power, Z-60/34, Z-80/60, GS-3390, GS-4390, GS-5390, and additional S, Z, and GS variants — cross-reference part number 88757GT against your parts manual to confirm compatibility with your specific machine.
Key Features
- Genuine OEM Fuel System Integrity — Manufactured to Genie's original specification, this valve delivers the correct lockout pressure response and connector fitment required for a properly functioning LP fuel circuit.
- Direct Drop-In Replacement — Engineered to match the original mounting configuration and electrical connector interface, allowing installation without adapters or custom fabrication.
- Broad Multi-Platform Fitment — Compatible with Genie S-series telescopic booms, Z-series articulating booms, and GS-series scissor lifts, making it a practical stock item for mixed fleets.
- Fuel Supply Control on Demand — Correctly regulates LP flow to the engine, ensuring the fuel system opens and closes as intended under normal operating and shutdown conditions.
- Critical Safety Function — On aerial work platforms powered by liquid propane, a properly operating lockout valve prevents uncontrolled fuel flow during shutdown or in the event of an engine fault — an essential safeguard for operator and site safety.
An LP lockout valve controls the flow of liquid propane from the fuel tank to the engine's fuel delivery system. When the engine is running and operating conditions are normal, the valve opens to allow fuel through; when the engine shuts down or loses electrical signal, the valve closes automatically, cutting off the LP supply and preventing raw fuel from reaching the engine or surrounding components. A failed or leaking lockout valve can result in hard starting, rough engine operation, fuel system leaks, or an inability to shut the fuel supply down reliably — all of which compromise both machine performance and on-site safety on propane-powered aerial equipment.
