to further complicate things, i have seen "regulator oscillation" problems with 2 in series.

Alot of these generator setups need 2       regulators, so usually the regular one stays at the tank, size the       pipe for the flow rate ( just like wire and amps.... ;-) .) and put the       2nd regulator right at the generator.

I carry a manometer to make check the pressure at the LP         input to the generator with the engine running. Make sure it       is at/above 11" WC when it starts to act up. If the regulator is       at the tank, long vapor runs can cause too much pressure loss.

Hi Guys
 
We have had                     “icing” problems here in Central America as well                     where the gas company put in ½’ pipe to a 12K                     Gillette Generator, same description the gen would                     initially start and run fine but then it went                     erratic the Radian didn’t like it, the customer                     wanted to blame the Radian (I was sure it wasn’t)
 
The                     installer/dealer couldn’t figure it out. I went out                     and immediately saw the small pipe, plus they had                     bent a crimp into the incoming fuel line as well. ¾”                     line fixed the whole thing. LP has a lot of moisture                     and will always have delivery problems with funky                     installation of pipe. Seems that a lot of gas guys                     just hook up kitchen ranges (Here)
 

Kind                       regards
