Just bought a Champion 2000 at Sam's Club for $489 plus $40 for 3 year extended warranty to use for my diesel Bounder. The diesel genset in the Bounder was running at least 3/4 of a gallon without a load so I figured the Champion would pay for itself in a moderate amount of time. It is much quieter also (it is a 6500K 1992 model)! For the times I need power just for satellite, TV and inverter it will work fine. I have read MANY of the pages on this forum looking for information on an external gas tank setup. There was some mention but I could not locate any post that mentioned successfully making and using one. Can someone spare me looking through the other 95 or so pages?
The external tank setup works when the generator has a fuel pump. The Honda, the Kipor (pretty sure) and the original Honeywell (XG-SF2000) have a fuel pump that is operated by pulsing vacuum from the engine.
On those, it's not a big deal to rig a line from an external tank to to a hole in the top of the gen's fuel cap and let the vacuum suck the gas from the external tank into the gen's tank.
On a gen without a fuel pump - such as my 80cc 1200w Champion synchronous generator, or the Champion inverter generator that this thread is devoted to - then to rig an external tank would require that it be a gravity feed setup.
That's a little trickier...
Probably the simplest way (and I've thought about this quite a bit) is an either/or valve so the gen runs either from the on-board tank, or flip the valve and it runs from the external tank.
But there's really no point with the gen I have now (Champion, but NOT the inverter gen discussed here). I have to add a bit of oil every time I fill the fuel tank (1.2g), so if I rigged a bigger external tank, I'd just run into a low oil shutdown eventually anyway.
