Product Overview

Onan carbureted engines use this pump to move fuel from the tank to the carburetor using crankcase pulse/vacuum. A worn diaphragm or check valves can cause long cranking, fuel starvation at load, intermittent stalling, or an empty carburetor after the machine sits.

Application information for 149-2501-01 describes the later square-style pump and notes that it can replace older rectangular configurations in supported installations. The pulse-port location and fuel-hose routing should still be matched carefully.

Key Features & Performance

  • Pulse/vacuum-operated fuel pump for carbureted Onan opposed-twin engines
  • Reference 149-2501-01 in matched Onan application data
  • Supports P216G, P218G, P220G, P224G and selected B43/B48 variants
  • Later square-style service configuration is commonly listed as a replacement for older pump designs on applicable engines

Specifications & Reference Numbers

  • Reference: 149-2501-01
  • Pump type: Pulse / vacuum diaphragm fuel pump
  • Fuel system: Carbureted gasoline engine

Before You Order

Check the pulse hose for cracks and verify the pump’s pulse-port orientation before installation. Incorrect hose routing or a weak crankcase pulse can prevent fuel delivery even with a new pump.

Frequently Asked Questions

Q: Is this pump electric?
A: No. This type is operated by engine crankcase pulse/vacuum.

Q: What if fuel still does not reach the carburetor?
A: Inspect the tank pickup, filter, fuel hoses, pulse line and carburetor inlet in addition to the pump.
