Lucky Seven A029F887 Electric Fuel Pump for Onan 5500 5.5kW Generators — 35 GPH Low-Pressure Direct-Fit

The Lucky Seven A029F887 electric fuel pump is a direct-fit replacement pump for Cummins/Onan 149-2620/A047N929 applications, supplying up to 35 GPH to maintain reliable fuel delivery for Onan 5500-series generators.

Designed to match the common fitments (Cummins Onan A029F887, A047N929, 149-2620) and cross-references such as Airtex E11015, Herko RV008 and GMB 596-1160, the unit is built for straightforward installation and steady low-pressure fuel flow for gas generator engines.

Will this pump fit my Onan 5500 (5.5 kW) generator?

How does the pump perform in terms of flow and pressure?

This electric pump delivers a steady free flow of about 35 gallons per hour (132 liters per hour) and is intended for low-pressure fuel systems typical of small gas generators. It maintains correct fuel supply without introducing excessive pressure.

• Free flow rate: 35 gph (132 lph)
• Maximum operating pressure: 5 psi — suited for carbureted or low-pressure EFI generator setups
• Female-thread inlet and outlet for standard plumbing connections

What are the physical and connection details I should know?

The pump uses female-thread fittings for both inlet and outlet and a 1/8 in.-27 inlet size, matching the thread standards used on many Onan installations. It arrives ready to replace the original unit, with electrical terminals compatible with typical generator wiring harnesses.

• Inlet: female threads, size 1/8 in.-27
• Outlet: female threads for conventional fuel line fittings
• Simple two-wire electrical connection for power and ground

What comes in the package and what should I check before installing?
