How to prevent generator vapor lock

I purchased a new fuel filter and fuel pump, and I am in the process of moving them outside the generator compartment, where they will not be affected by generator heat. Mine will be in a metal box I bought from Home Depot. I am also replacing all rubber fuel hoses all the way to the tank and making sure they are nowhere near a heat source. Some others have gone as far as fabricating a louver and venting system on the door of their motorhome, since it all seems to be heat related
