XYWZV Electric Fuel Pump E11015 for Onan 5500 (5.5KW) Generators — Drop-in Replacement, Bench-Tested

The XYWZV Electric Fuel Pump E11015 is a drop-in replacement fuel pump engineered to restore reliable fuel delivery for Onan 5500 (5.5KW) gas generators, including Marquis Gold 5500 and compatible HGJAA/HGJAF models.

If your Onan RV generator is showing signs of inconsistent running, sputtering, or hard starts, a worn fuel pump is a common cause. The E11015 matches the original equipment fit and flow characteristics for several Onan/Cummins models and replaces OE numbers such as 149-2620, A047N929, A029F887, A064S965, GMB 596-1160, and Herko RV008. Each unit is bench-tested before shipping to ensure plug-and-play operation and includes PVC valves for hose connections.

How will this pump affect my generator’s starting and idle behavior?

Replacing an ageing fuel pump with the E11015 restores consistent fuel pressure and flow, which helps eliminate hard starts, stumbling, and erratic idling. The pump is specified to match the original fuel delivery rates to maintain stable engine performance under typical RV loads.

• Restores proper fuel pressure and steady flow.
• Reduces sputtering during startup and at low throttle.
• Designed to fit original mounting and hose connections.

Is installation difficult—what tools or preparation are required?

Installation is straightforward for anyone comfortable working on small engines and fuel systems; the pump is tested for plug-and-play fit. No installation tools or printed instructions are included, but you’ll find many step-by-step videos and guides online to follow.

• Remove dust cap before installation to avoid debris.
• Includes two PVC valves for secure hose attachment.
• Confirm model number and compare photos before purchase to ensure compatibility.

Which generator models and part numbers does this replace?

This pump is compatible with Cummins Onan RV QG and Marquis Gold 5500/7000 series and Emerald Advantage 5500 models, plus HGJAA/HGJAF variants. It replaces multiple OEM references so it’s easy to find as a replacement for common Onan part numbers.

What comes in the package and is the pump tested?
