BioLion Onan RV QG Oil Change Kit for 5500/7000 (HGJAA/HGJAB/HGJAC) — filters, spark plugs & electric fuel pump

Complete service kit for Onan RV QG 5500 and 7000 generators that replaces oil, air, fuel filters, spark plugs and includes an electric fuel pump for a full maintenance refresh.

Keep your Onan HGJAA, HGJAB or HGJAC series RV generator running reliably with a single, OEM-grade aftermarket package. This kit groups the most commonly replaced wear items—oil filter, air filter, fuel filter, spark plugs—and an electric fuel pump matched to the Onan 5.5/7.0 kW QG platform, saving you shopping time and ensuring compatible parts.

What parts are included and how do they match my Onan model?

The kit bundles one oil filter (replacement for part 122-0836), one air filter (140-3116), the fuel filter (149-2341-01), two F7TC spark plugs, and an electric fuel pump compatible with Onan RV QG 5500/7000 generators. Also included are a KL fuel filter and four hose clamps for secure installation.

• Oil filter: fits Onan RV QG 5500/7000 series (122-0836).
• Air filter: replacement 140-3116 designed for the same models.
• Fuel filter: 149-2341-01 to protect injectors and pump.
• Fuel pump: electric pump models listed for direct fit and proper flow.

How will this kit affect routine maintenance and downtime?

Replacing consumables together reduces repeat service intervals and helps prevent common failures caused by clogged filters or weak pumps. Doing a grouped service means fewer trips to parts suppliers and less generator downtime since each item is designed for straightforward replacement.

• Batch replacement saves time versus individual part sourcing.
• Fresh filters and pump restore proper fuel flow and filtration.
• Includes clamps and spark plugs to complete a typical service job.

Is the electric fuel pump compatible with my Onan QG generator and accessories?

The included electric fuel pump is matched to common Onan part numbers and OEM specifications for the RV QG 5500/7000 family, including direct-fit applications on Marquis and Gold units. Verify your existing pump part number or compare the pump appearance with product photos to confirm fit before installation.

• Compatible pump numbers: E11015, 149-2620, 596-1160, A029F887, A047N929.
• Designed for gas-powered Onan RV QG 5.5–7.0 kW generators.
• Contact seller support if you need part-number verification.

What tools and skills are needed to install the kit components?

Basic hand tools and moderate mechanical ability are sufficient for most of the included items: oil and air filters, spark plugs and fuel filters install with common sockets and screwdrivers. Replacing the electric fuel pump may require slightly more access and fuel-line handling; follow safety steps and depressurize the fuel system before beginning.

• Common tools: oil filter wrench, socket set, screwdrivers, pliers for clamps.
• Safety: work in a well-ventilated area, avoid open flames, and dispose of fluids properly.
• If unsure, have a certified RV mechanic perform pump installation.

Who this kit is for: RV owners, mobile mechanics and fleet managers who operate Onan QG 5500 or 7000 generators and want an economical, matched-service package. It’s ideal for planned seasonal maintenance, roadside preparedness, or restoring a generator showing fuel delivery or filtration issues. If you need help confirming fitment, check original part numbers against the supplied list or contact customer support for assistance.
