convert gas generator to propane

Has anyone done this conversion on a Onan 4K and what was the cost and where did you find the best price on parts needed.

Thanks John
  • I've had mine for 8 years and use the generator very, very infrequently, and have had no issues with the carb gumming up. I thought it would be an issue since we are fully connected almost all the time. But it hasn't been a problem. I drain the carb bowl after I'm through using it, and it always starts right up when I start it again months, sometimes many months, later. It usually gets started maybe once or twice a year. I never use any stabilizer, never drain the gas tank, and the same gas has been in there for a good 5 years. Like I said, so far no problems.

    Now watch, it won't run for sour apples this year. LOL
  • wildtoad, no it is in a 5er,

    fj12ryder, yep getting tired of a gummed up carb after sitting longer than two months and yes I do know propane use will be higher and cost a little more.
  • I've thought about doing it with my 5500 Onan, just to make sure that it doesn't get gummed up with gas when it sits for long periods. I've not done it, but it looks relatively easy to do and there are kits on Ebay, and other places that make it look pretty easy.

    OTOH, if you use the generator much propane usage is pretty high.
  • If this is in a motor home why would you do that unless it’s permanently parked somewhere.
