I'm real ignorant on this kind of stuff.

Hmmm in the section titled KEEP THE GENERATOR ORIGINAL - "Larger
auxiliary tanks added to the system will create more pressure on the
inlet needle valve which may cause the inlet needle to lose its
ability to regulate the fuel flowing into the carburetor. This may
cause the crankcase engine oil to become diluted with fuel, spark plug
and spark arrestor carbon build-up, and possible external fuel leaks
which may result in fires."

My boss made the mod on his 2000 watt Honda. All you need is a spare
gas cap. I can't go into the "mod" too much since I didn't so it
myself, but I am told that it involves simply attaching the boat tank
line to the gas cap after a hole is drilled in it and a connector is
installed. And he states that it is easy to refill the system at the
boat tank while running. Apparently the air that gets in does not
really affect things since while the real tank on the generator may end
up with some air in it, it still ends up with enough vacuum to continue
to pull fuel after a refill.

He has run it for a week at a time before. Also the pressure has much
to do wih how the modification is done and how you use the system
afterwards. Honda is probably covering their butt, and for good legal
reasons.

Many have done this mod, and know of the potential problems. I have not
read of any. I would say that you just have to keep track of the
potential problems and don't do something that would raise the fuel
pressure.

And again, I do NOT own one of these generators. I have modified 2
others, which were not Honda, with direct connections to the carbs from
a boat tank. No issues after hundreds of hours of use.
