Wacker Neuson 5000156548 Air Pilot Jet

The Wacker Neuson Air Pilot Jet is a genuine OEM component designed for a broad range of Wacker Neuson equipment, including PT2 trash pumps, CT36-6 concrete trowels, GP2600 portable generators, PDT2 and PDT3 diaphragm pumps, PG2 and PG3 dewatering pumps, VP and WP series vibratory plate compactors, BFS floor saws, and BPU reversible vibratory plates. Sourced directly from Wacker Neuson, part is manufactured to the exact OEM specification of the original component it replaces, ensuring a correct carburetor circuit match across every compatible platform. With such wide cross-model coverage, this single jet number is a practical stocking part for dealers and rental fleets running mixed Wacker Neuson equipment.

Key Features

• Correct Carburetor Circuit Sizing — Calibrated to the original fuel-to-air metering specification so the pilot circuit delivers the right mixture at idle and low throttle, preserving clean starting behavior.
• Genuine OEM Part — Supplied as an authentic Wacker Neuson component under part number 5000156548, identical in material and orifice diameter to the part that left the factory.
• Broad Cross-Model Compatibility — A single part number covering PT2 pumps, CT36-6 trowels, GP2600 generators, VP/WP vibratory plates, PDT/PDI diaphragm pumps, PG dewatering pumps, BFS floor saws, and BPU reversible plates — ideal for multi-machine fleets.
• Direct Carburetor Drop-In — Threaded to the OEM pitch and seat dimensions, the 5000156548 installs into the carburetor body the same way the original did, with no re-jetting or seat modification needed.
• Stable Idle and Throttle Response — A worn or clogged pilot jet causes rough idling, hard starting, and lean-running conditions; replacing it with a correctly sized OEM jet restores smooth low-speed fuel delivery and consistent throttle pickup.
• Fuel System Integrity — Because pilot jets govern fuel flow in the critical low-load circuit, using the correct OEM-spec orifice helps prevent lean operation that can accelerate engine wear over time.

The pilot jet — sometimes called the air pilot jet — is a small, precisely drilled carburetor component that meters fuel flow through the idle and low-speed circuit. At startup and light throttle, the engine draws fuel almost exclusively through this circuit, so even a minor blockage or orifice wear will cause hard starting, rough idling, or a stumbling low-end response. When a pilot jet fails or becomes fouled with varnish from stale fuel, the engine may refuse to idle, run excessively lean, or require the choke to be held partially closed just to maintain speed — replacing it with a correctly sized OEM jet restores clean, stable combustion from the moment the engine fires.
