By "run gas and LPG" do you mean that you want both fuels going into the engine at the same time? Or do you mean that you want to be able to carry both fuels and select between them?

Interesting project. Do you have a background in LPG conversion and any technical competence? Or just a yen?

I found some general plans on how to do a conversion.
It will allow to run gas or LPG but not both at once. It has a simple push button to swap fuels. It seems easy to do and I am looking for all of the parts. My fear is loosing power by running just LPG. With that in mind I may just do the conversion then modify it from that to run both fuels like 2/3 gas 1/3 LPG and possibly some way to adjust the mix from the cab.


I have seen diesel and LPG mix conversions but never gas and LPG.

Hit up the Ausrotary forum...they use LPG quite successfully over there, even turbocharged! I believe it is the same as propane. They have special LPG carbs over there too!
