We have had requests on kits for the EU7000is. Unfortuanly this generator is operated by an electric fuel computer control module. Which is much different than a simple carburetor used in most small engines.
To properly equip the EU7000is generator to run on alternative fuel and have it perform to full factory power output would mean developing a electronic bypass for the computer engine control module.
We do believe EFI is the future for small engines as EPA and CARB pushes for cleaner emissions.
At the moment there is no kit for this generator until further R&D is completed, which is unknown at this time.
