Will this kit work for model 4kyfa26100k ?

No, this kit will not fit your model. You will need our Tune Up Kit for Onan RV Generator Model KY 4000, Spec A-P Non-Evap Models Thanks for your question!

Will this fit a 12.5 kw?

Onan is pretty good about putting the model number labels and service part numbers on your generator. Check the white label On your generator and compare to the ‘fits models ‘ description for this product. Search for ‘Onan tune up kit (your model)’ will get you correct kit.

Will this work for a 12.5 jc-3cr/2701aa?

Unfortunately, this kit is only for the models listed. I will check into what parts are available and work on putting a kit together for you. Thanks Lindsay GPS

I have a 7500 spec h. The unit gives this part number for the oil filter: 185-5409. Is that the same filter? All other numbers you list seem to match

The part number 185-5409 supercedes to 122-0833. I can confirm it's the right kit for your unit by your model number if you would like to provide it. Thanks!
