WDPART E11015 Fuel Pump Kit for Onan 5500 RV Generators — Includes 149-2341-01 Filter, 13" Harness

WDPART E11015 is a drop-in fuel pump kit that includes the matched 149-2341-01 fuel filter, designed to replace the original pump on Cummins Onan 5.5 kW RV generators for reliable fuel delivery.

This kit pairs a tested E11015 fuel pump and the 149-2341-01 filter so you can restore proper fuel flow without time-consuming modifications. The assembly arrives with factory-installed dust caps, a 13-inch wiring harness, and a small residual fuel test mark that indicates plug-and-play verification. It’s made to fit several Onan RV generator families including QG, Marquis Gold, and Emerald Advantage in the 5500/7000 size range.

Will this pump fit my Onan 5500 generator?

Yes—this E11015 kit is listed for Cummins Onan RV QG 5500/7000, Marquis Gold 5500/7000, and Emerald Advantage 5500 models. Confirm compatibility by matching the part number and physical connector style to your existing unit before installation.

• Compatible models: Onan QG, Marquis Gold, Emerald Advantage (5500/7000).
• Check the original pump’s mounting pattern and electrical connector.
• Package lists one OE# but the kit fits all OE numbers referenced in product details.

How difficult is installation and what tools are needed?

Installation is straightforward for someone comfortable with basic mechanical tasks. You’ll remove dust caps, attach the filter to the inlet using a wrench, connect the 13-inch wiring harness, and verify tight, leak-free fittings—take care not to overtighten the filter.

• Tools: wrench for the fuel filter, basic hand tools to access pump location.
• Pre-installed dust caps protect connections during shipping—remove them before use.
• Follow generator service manual steps for safe fuel-system work and proper grounding.

What should I expect in the package and why is there fuel inside?

The kit includes one WDPART E11015 fuel pump and one 149-2341-01 filter. A small amount of fuel may be present—the manufacturer tests the pump for functionality prior to shipping to ensure plug-and-play operation.

• Contents: 1 fuel pump (E11015) and 1 fuel filter (149-2341-01).
• Fuel residue indicates bench testing and does not affect performance.
• Only one OE number may be printed on the box despite broader compatibility.

How can I maintain performance after installation?

Regularly inspect fuel lines and filter condition, replace the filter according to the generator’s maintenance schedule, and check electrical connections for corrosion. Keep a spare filter on hand to minimize downtime if you rely on your generator for RV or backup power.

• Periodic filter checks prevent restricted flow and running issues.
• Ensure wiring remains secure and free of chafing or corrosion.
• Store the pump and spare parts in a dry, ventilated area when not installed.
