You'll need a low-pressure electric fuel pump (to replace the one on the Onan you yanked out of the RV), along with an adjustable fuel pressure regulator to reduce the fuel pump's 4-5 PSI output to just a small fraction of a PSI (which is what the pressure coming out of a gravity-fed fuel tank would normally be).
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. they even showed a photo of the set up.
Honda sells the tank and the "Modified" gas cap needed to use it.
The procedure is fill the "on board" tank. and the external. replace the original gas cap with the "extended run" cap and it sucks the extended tank dry. You then swap caps back (Running off the on board) While you run to ye old fuel pump to refill the extended tank.. Can run a long. long, long time that way.
TO THE ORIGINAL POSTER
Be sure to put a shut off valve line (two in fact) in the line from the RV's primary tank. One manual and one "Quick Disconnect" type to insure the line does not express fuel when the tank is filled.
