After I hit the send button, I thought about how a small generator
or gas grill will use tank pressure through a vapor regulator. If
this generator is plumbed that way, there lies a problem that your
solution of heating the tank will work with. Personally I would not
plumb a generator with vapor lines from the tank, especially is it
is a long distance away. Since Gary said this was a large system, I
am assuming it is liquid delivery to the generator.<br>
<br>
Gary, is the LP to the generator vapor or liquid from the tank?<br>

to let it vapourize. Think about putting it somewhere with a
little heat, or burying it.</div>

<div text="#000000" bgcolor="#FFFFFF"> About the carb heat
idea...LP is a liquid at -44°F. The liquid does not
combust, it must be vaporized. As the ambient temperature
drops closer to the LP liquid temperature, there would be
a reduction in how fast liquid is vaporizing and therefor
a reduction in volume. What you need in cold weather is
enough volume to maintain at least 11" wc while cranking
or running the engine. You can test the vapor pressure
with a manometer while cranking to verify if this is the
problem. <br>
<br>
If this is the reason the engine does not run, my thoughts
are that heating the LP regulator would be much more
economical from an energy standpoint, than heating the
whole engine block. Perhaps an insulated enclosure with
silicone heaters appropriately attached would work. They
are available in many DC or AC and at various voltages.<br>
