Podoy 12V Electric Fuel Pump for Onan/Cummins 4000 4KW Generators — Model 149-2311, 15–25 GPH Low-Pressure Replacement

This direct-replacement fuel pump is designed for RV and motorhome gas generators where consistent low-pressure fuel delivery is required. Engineered to match the 15–25 GPH flow and roughly 2.5–4 PSI operating range, the Podoy 149-2311 fits popular Onan/Cummins 4KW Microlite and MicroQuiet generator families and several QG4000 variants. The unit ships as a single pump and is constructed from materials intended for durable, leak-resistant service in mobile power applications.

Will this pump fit my Onan or Cummins 4000 4KW generator?

If your generator lists part numbers such as 149-2311, E11007, A029F889, or similar 149231101 variants, this Podoy pump is made to be compatible. Compatibility also extends to many Microlite, MicroQuiet and QG4000 models commonly installed in RVs and motorhomes. Always compare mounting points, electrical connector type and inlet/outlet hose sizes before installing.

• Compatible with Onan/Cummins 4000 4KW Microlite/MicroQuiet models
• Fits QG4000 and related 4.0KYFA/26100 model families
• Cross-references: 149-2311, 149-2311-02, 149-2311-01
• Verify connector and hose dimensions for exact fit

How much fuel flow and pressure does this pump provide?

The Podoy 149-2311 is rated to move approximately 15–25 gallons per hour at low pressure, suitable for small generator carbureted fuel systems. Its operating pressure range centers around 2.5–4 PSI, matching the low-pressure requirements of many 4KW gas generator setups. Those figures help ensure stable engine running and reduce the chance of fuel starvation under normal loads.

• Flow rate: 15–25 GPH for steady fuel supply
• Pressure range: ~2.5–4 PSI for carbureted systems
• Optimized for small generator fuel lines and fittings

What are the build quality and installation details?

Constructed from durable materials, the pump aims for long service life and a leak-resistant seal to maintain continuous fuel delivery. Installation is straightforward for mechanically minded owners: disconnect battery power, relieve fuel pressure, swap the old pump for the new unit, then reconnect hoses and electrical leads. Use replacement gaskets or clamps as needed and test for leaks before running the generator under load.

• Durable housing and internal components for extended use
• Designed for easy swap-in replacement with matching mounting points
• Includes one 149-2311 fuel pump; hardware may be reused
• Not affiliated with or endorsed by Onan or Cummins

What should I check after installing the new fuel pump?

After installation, inspect all hose connections and clamps for signs of seepage, then run the generator and watch for steady engine speed and smooth starts. Listen for unusual noises and confirm there are no fuel odors near the mounting area. If performance is uneven, recheck electrical connections, grounding and fuel supply routing.

• Check hose clamps and gaskets for leaks
• Verify electrical connector is secure and fused appropriately
• Run generator and monitor for steady RPM and fuel delivery
• Address any leaks or noise before extended operation

This Podoy 149-2311 fuel pump is intended for RV owners, mobile technicians and fleet maintainers who need an economical, reliable replacement for Onan/Cummins 4000 4KW series generators. It’s best for applications that require low-pressure, moderate-flow fuel delivery—particularly older carbureted generator models in RVs, motorhomes and small service fleets. If you’re unsure about fitment, consult your generator manual or a qualified technician to confirm part interchangeability before purchase.
