The Genie 85155GT is a genuine OEM Perkins Primer Pump built for Genie AL and RL series light towers and select Genie Z series articulating boom lifts. As a direct OEM replacement, this pump is produced to the same specifications as the original component installed at the factory, ensuring a correct fit without modification. Confirmed fitment includes the AL4000, AL4, RL4 light towers, and Z-62/40 and Z-34 IC boom lifts — cross-reference part number 85155GT against your machine's parts manual to verify compatibility with your specific unit.
Key Features
- Genuine OEM Quality — Manufactured to Genie OEM standards for the Perkins engine application, delivering the same dimensional and material conformity as the factory-installed component.
- Direct OEM Replacement — Engineered to install in place of the original primer pump without adaptation, preserving correct fuel priming function.
- Broad Genie Fitment — Compatible with Genie AL and RL light towers (AL4000, AL4, RL4) and Z series articulating boom lifts (Z-62/40, Z-34 IC), covering multiple Genie equipment families.
- Reliable Fuel Priming — A correctly functioning primer pump ensures the fuel system is primed before engine start, enabling clean, consistent ignition and reducing the risk of hard-start conditions.
- Operational Confidence — Replacing a failed or degraded primer pump with a genuine OEM part restores the engine's designed starting performance, keeping powered equipment ready for use.
A primer pump is a manually operated component that draws fuel from the tank into the fuel system, purging air from the lines before engine start. On Perkins-powered equipment, a functioning primer pump is essential for reliable cold starts and after any fuel filter service or line disconnection that may introduce air into the system. When the primer pump fails — due to a cracked body, degraded internal check valves, or a seized mechanism — the engine can become difficult or impossible to start until the air is cleared by other means. Replacing a worn pump promptly restores normal priming function and protects the fuel system from the strain of repeated cranking attempts.
