Propane to 4KW onan

[SteveW]

Greetings from Southern California -

Has anyone done a "dual fuel" conversion to a 4KW onan generator... In a 23 footer ??

Jerry -

Might it be significantly different than your Western States write up ??

Thanks in advance for your comments.

As you guessed, the Western States presentation by Jerry Work will not work in the 4K Onan. There's no space to mount the fuel control module on the
4K engine. I believe I've seen a propane modification where the fuel control was mounted at the back of the battery compartment which is a
possiblity. Aside from the mounting logistics, most of the parts from WS Carb would be needed to convert the 4K.

Thank you Captain Jack !!

I'll poke around for a location... My onan battery compartment is already stuffed with two 12V Optima (house) batteries.

I figure that the carb "insert" will be the same.

How far away (from the carb) can the fuel control module be ?? I suspect that this distance is not a critical factor...

Thanks again,

Gnen,
Congratulations I didn't think it could be done! It looks like the generator compartment was also modified. Was that a requirement? Also, the
control module isn't that close to the carb where the injector is located which was a concern.
