Can I use a gas grill propane hose with regulator or do I need to use a 2- stage hose with regulator with my generator?
It likely depends on the exact models of generator and regulator. I use a single stage regulator to feed the demand regulator on the generator that feeds a snorkle (MSK3101 kit).

Tabora has the proper set up shown.
There is a plus with this set up, it can be switched from Propane to Natural Gas with a minor adjustment.

I have a Champion 100155 with stock dual fuel connections which I bought used. The seller lost the 2-stage regulator and hose that came with it.
Looks like your demand regulator is part number 47.136000.01 and is most likely looking for 11" WC (= 6.36 ounces / in2) for input. This regulator would do it:

The Champion regulator with hose is part number 47.130021.01

I already have that info. My original question was can I use a gas grill propane hose with a regulator with my generator? It is my understanding that a standard gas grill regulator is 11" WC.

It may or may not be and may or may not pass enough fuel. Read this:
The one I purchased does pass enough for 11" WC demand (my demand regulator wants 6 ounces / in2 = 10.38" WC up to 8 ounces = 13.84" WC Max). However, I paid almost as much as the actual Champion part I provided you in the link. Mine does have QD fittings, though.

Keep in mind that a grill regulator is not a "demand regulator". If your gen quits and you do not have a "demand regulator" then propane will keep dumping in to the carb with no where to go, like a grill that has the valves open but no flame - you puke propane out and cause a hazard.

There is a reason for the demand regulator.

There are ways to go around a demand regulator - for example, with an electronic valve that automatically closes with loss of power (gen quits). However, the best route is a mechanical, non-powered conventional demand regulator that works on a vacuum (presented by the draw from the carb with the engine running or choked to start). That is what the pancake style regs are for.

No matter what, it is critical that you have a method of cutting off the fuel so it isn't dumping out if the engine isn't running.

His Champion 100155 does in fact have a demand regulator built in... See post #5.

That is a different set up than mine then. The main point holds true - that there is a way to cut fuel off if the engine quits.

The regulator set on mine is PN 63.130000.00 - 3 main parts - the hose + fittings, high pressure reg, and demand reg. So it appears they have them set up different ways on different models.

Personally, I like the on-board demand reg idea - so its always there. But, it does add a bit of weight to a "portable" unit.

Just to be clear, his demand regulator is part number 47.136000.01 (part #104 in the diagram) and IS built into the generator. It's right behind the sheet metal #139.
