TuLeYiLe Oil Change Kit for Onan RV QG 5500/7000 is a complete tune-up set containing fuel, air and oil filters, two spark plugs, a gap tool, oil-filter wrench and clamps to service your generator quickly and correctly.

This kit gathers the routine replacement parts and the few specialty tools needed to perform a full basic service on Onan RV QG 5500 and 7000 series generators. All components are matched to the common OE service parts used on Marquis Gold/RV QG and Marquis Platinum QG EFI models and the HGJAA/HGJAB/HGJAC family of engines. With the parts on hand and the included tools, typical maintenance tasks like filter swaps and plug changes take only minutes and reduce downtime during trips or seasonal storage.

What parts are included and why they matter?

The kit contains the filters and ignition parts that most commonly need replacing during a scheduled service interval. Fresh fuel, air and oil filtration plus new spark plugs help the engine run reliably and resist damage from contaminants or fouling.

• 1 x 149-2341 fuel filter — prevents debris from reaching the carburetor or EFI system
• 1 x 140-3116 air filter — improves combustion by keeping dust and particles out
• 1 x 122-0836 oil filter — captures metal and sludge between oil changes
• 2 x 167-1638 spark plugs — restore ignition consistency and easy starts
• 1 x 627-0560 gap tool and 1 oil-filter wrench — included to speed installation
• 4 x clamps — secure fuel lines and filter fittings

How do I use this kit for a quick generator service?

The kit is designed for straightforward swaps: drain oil, replace the oil filter, change the fuel and air filters, then fit new spark plugs. The included oil-filter wrench and gap tool eliminate the need for extra specialty items, so most steps are reachable with common hand tools and basic mechanical experience.

• Drain and replace engine oil, then fit the supplied oil filter using the included wrench
• Remove and install the air and fuel filters, replacing clamps where needed
• Fit new spark plugs and set the correct gap with the included gap tool
• Run the generator briefly to check for leaks and correct idle/operation

Which generator models and variants are compatible?
