AULDAY Fuel Pump Kit for Cummins Onan 5500W RV Generators — 149-2620 Pump & 149-2341-01 Three-Layer Filter, Direct-Fit Replacement

AULDAY's 149-2620 fuel pump kit with the 149-2341-01 three-layer fuel filter is a direct-fit replacement for Cummins Onan 5.5KW (5500) RV generators, restoring reliable fuel delivery and cleaner fuel to the engine.

This replacement kit combines a precision fuel pump (E11015 / 149-2620) and a high-efficiency fuel filter (149-2341-01) engineered to fit Marquis Gold, Marquis Platinum, QG EFI and other compatible Onan RV generator models. Built with an Italian three-layer synthetic filter medium and robust pump components, the assembly is designed to reduce contaminants and water in the fuel system so injectors and engine components run cleaner. The kit ships complete with the pump assembly and filter element to simplify service and minimize downtime.

How will this kit affect my generator's starting and idle behavior?

Replacing an aged or clogged pump and filter often restores consistent fuel flow, which helps the engine start more reliably and hold a stable idle. Improved fuel delivery reduces sputtering and lean-run symptoms caused by restricted flow or contaminated fuel.

• Direct-fit pump (149-2620 / E11015) for correct pressure and flow.
• Three-layer synthetic filter removes particulates and water.
• Complete kit avoids mismatched components and installation delays.

What models and engines are compatible with this AULDAY replacement kit?

The kit is specified to fit a range of Cummins Onan RV generators, including the 5500W (5.5KW) EVAP models and Marquis Gold/Platinum QG series, plus related Microlite/RV QG units. Check your generator part numbers or owner manual to confirm match with 149-2620 (pump) and 149-2341-01 (filter) before ordering.

• Compatible with Onan 5500W EVAP and Marquis Gold/Platinum QG generators.
• Fits applications requiring E11015 or A029F887 pump equivalents.
• Ideal where factory numbers 149-2620 and 149-2341-01 are listed.

How difficult is installation and what should I prepare?

Installation is straightforward for anyone comfortable with basic generator maintenance: depressurize the fuel system, remove the old pump and filter, and swap in the new components using the supplied or factory fittings. Typical tasks include disconnecting fuel lines, electrical connectors and mounting fasteners; no special machining is required.

• Shut off fuel and battery before starting work to ensure safety.
• Have common tools ready: wrenches, screwdrivers, pliers and a catch pan for residual fuel.
• Follow generator manual torque specs and bleed the system after fitting.

What materials and warranties back this replacement pump and filter?

The filter uses Italian three-layer synthetic fiber media for fine particulate and water separation; the pump uses OEM-equivalent materials and calibration to match factory flow characteristics. AULDAY provides a 12-month warranty on the product plus lifetime technical support to help troubleshoot fitment or installation questions.

• Filter: three-layer synthetic fiber, water-resistant design.
