It is likely that the conversion only requires the carb and demand valve from a HPS9000VE, but you can compare them and see.

I'm with GenKnot. Convert it to LP gas and get a couple of 30lb tanks to swap-between, or larger (100lb is next) as you might need.

Propane stores "forever" vs gasoline.

 

@nopeda Perhaps look into converting the gen to propane by using parts from (or similar to) the Winco HPS9000VE. Fuel storage is an issue with gasoline. It has to be constantly rotated (used up in your car) even with stabilizer.

 

Would it be best to just get rid of the 4.5 gallon and get maybe a 12-15 gallon somewhere? The 7 gallon doesn't seem quite large enough.

Were it me, thats exactly the route I'd take. I think you'd find the 7 gallon to be a good improvement but in your case it sounds like more is better. Any auto racing shops in your locale? They've usually a large amount of tank size options you can look into. Some are apt to be able to custom make a tank to your requirements.

Also not having easy access to non-ethanol gas I was planning to add Sta-bil to every tank hoping that would make it last a long time and be good for the carburetor. Use that for lawn mowers and snow blowers also. Is that a good way to deal with the ethanol issue?

Yes, absolutely(!) use a fuel stabilzer. Myself I prefer and recommend the blue marine brand from Sta-Bil but I also throw Seafoam in there with every tank.

 

I live in the Deep South. Probably the only time I would need a generator would be after a hurricane. The heat and humidity is stifling without AC (during summer). I picked a generator that would run all night for that reason.

 

Maybe you could explain to us why 6 hour run time isn’t enough for you? During an emergency it’s best to run a generator sparingly because you don’t know where the next fill up is coming from or even available. Simply shut down the generator overnight if possible and start it up again at breakfast time, after refueling and checking/changing the oil. Portable generators aren’t designed to run for many hours anyways. However, several inverter generators use fuel pumps and many of those are easily retrofitted with extended run systems simply because they pump fuel. Gravity feed systems are dangerous because there’s little/no control over fuel flow, which is a fire hazard.
