With most makes of generator you are correct.

With a HONDA. they put on on the generator at the factory.

As someone posted up thread the HONDA is designed to suck fuel from an external "Extended run" tank.

Drawing fuel from a tank sitting right next to the generator isn't the same as drawing it through several dozen feet of fuel line to a tank mounted somewhere else on the RV.

Depending on the particular RV, there may also be some additional restriction from a fuel filter.
