  • Unfortunately, running a gas engine on diesel can cause damage due to the differences in combustion properties between diesel and gasoline. Here's what you can do:

    Remove all diesel from the fuel tank and clean the fuel lines, injectors, and other affected parts of the fuel system to prevent further damage.

    Replace Fuel Filter and Components: It's highly likely that the fuel filter has been affected. Consider replacing the fuel filter and any other damaged components to ensure the proper functioning of the fuel system.

    Engine Flush: Consider performing an engine flush to remove any remaining diesel residue and contaminants from the engine. This step can help prevent potential issues caused by the wrong fuel.

    If poroblem presist after clenaing the fuel tank, flushing the engine and replacing the fuel filter, then the next step is replacing the fuel pump. If the problem is still present, then the next step is the fuel injectors.
