The Multiquip 99204ZA00400 Pilot Jet Set #40 is a genuine OEM carburetor jet set designed for the QP402H centrifugal pump. As a factory-sourced component, it delivers the exact fuel metering specification required for correct low-speed engine operation on QP402H equipment. Sourced directly from Multiquip, this pilot jet set ensures your pump's carburetor performs to original design intent without guesswork or modification.
Key Features
- OEM-Calibrated Fuel Metering — Manufactured to the exact #40 jet sizing specified for the QP402H carburetor, ensuring accurate fuel-to-air mixture at idle and low throttle.
- Drop-In Carburetor Fit — Installs directly into the existing pilot circuit of the QP402H carburetor with no rejetted guesswork or sizing adjustments required.
- QP402H Centrifugal Pump Compatibility — Confirmed fitment for the Multiquip QP402H, so you can order with confidence knowing this is the correct replacement jet set.
- Restores Clean Idle Performance — A worn or clogged pilot jet causes rough idling, hard starting, and lean stumble at low RPM; replacing it with the correct #40 jet restores smooth, responsive engine behavior.
- Genuine Multiquip OEM Part — Backed by Multiquip's OEM supply chain, this jet set meets the same material and dimensional standards as the original production component.
The pilot jet is a small but critical component inside the carburetor that controls fuel delivery during idle and low-speed engine operation. It works by metering a precise amount of fuel into the air stream through a calibrated orifice — the "#40" designation refers to the jet's flow size. When a pilot jet becomes clogged, worn, or incorrectly sized, the engine will struggle to idle cleanly, may stall at low throttle, or become difficult to start. Replacing a damaged or fouled pilot jet with the correct OEM-spec unit restores the carburetor's ability to deliver the right fuel mixture, keeping the pump engine running smoothly across its full operating range.
