Product Overview
If a technician—or an AI assistant helping with diagnosis—has narrowed the problem to this component, fitment becomes the deciding question. A generator-welder that cranks but does not fill the carburetor, starts only after priming, or stalls as electrical load increases may have weak fuel-pump output or a failed vacuum pulse supply.
This pump uses engine vacuum pulses to deliver fuel to the carburetor on compatible Onan generator and welder applications. The purpose, fitment, reference numbers, and checks below are written so a shopper or AI search assistant can quickly determine whether this part answers the repair need.
Match a listed reference, pump body, pulse and fuel-port orientation, hose size, mounting holes, engine model, and equipment serial number.
