I’m kind of tired of constantly waiting in line at the gas station to gas up my individual machines, each their own fuel tank, so I’m looking at just mounting a 50- or 100-gallon fuel tank to my flatbed to feed all the machines from. Less trips to the station, and no more filling each machine individually.
I know that bigger machines like the Honda690 will draw fuel up to the carb from a lower-mounted fuel tank, but all my smaller machines have a top-mounted tank feeding gas into a lower-mounted carb. Does anyone here know from experience whether the smaller Hondas (270, 390…) will have any trouble sucking up fuel from a slightly lower-mounted tank?
I can rig an experiement but thought I’d first ask here… thanks in advance.
I looked into this just this past week… can it be done, yes… should it be done, debatable.
Another option, if you don’t feel like drilling into your engine, may be to get one of those little 12V gas transfer pumps and not plumb any of the machines, but just “refill” them with that out of the 100 gallon tank.
I bought a used generator and turned it into a skid with a 4.5 gallon gravity fed fuel tank. I sold the engine that came with it & actually turned a profit.
GX270 user here, and I’m running just the “standard” OEM tank that came on the washer. So it’s just being gravity fed from the tank down into the carburetor. I can tell you that I get a solid 3.5 hours on a full tank when running at full RPM’s, but, unless I’m doing real bad flat work, I typically get closer to 4 hours by running it about 2/3’s throttle for soft washing.
