Already Have a Generator


You can count on gasoline . . . to let you down!

Gasoline is not a fuel that professionals ever choose to use on backup generators. 

Hospitals and other large facilities "never" install a gasoline back-up generator. They always use natural gas or diesel. Gasoline has a very limited shelf life and will actually cause engine failure. Worst of all when power outages occur due to ice storms, hurricanes, tornadoes, earthquakes and all other disasters, the first commodity to be hoarded is gasoline. Sadly, long lines (even fist fights) and rationing at gas pumps are a common occurrence during many disasters. 

Unfortunately, as some have learned the hard way, if not used often enough, gasoline will gum up the carburetor and will render an engine on the emergency generator useless.

Do not get caught with a gummed up carburetor that will not allow your engine to run, on your gasoline generator that you cannot even get fuel for, when you need it the most.

Now that you have invested in a backup generator, make sure that it runs when you need it the most. We can modify your Generator to run on propane, natural gas, and/or gasoline. Our Trip-Fuel builds give you the option to run all three fuels, on the same engine!  

You can use what you can get at the time- gasoline, propane, or (SNG) natural gas!

Propane and natural gas can save you time, money and aggravation. 

Your engine will last longer, start better in cold weather, and even start next year when you go to use it in an emergency! 

Wouldn't you rather have a dependable generator when it counts?


Why use propane to power your generator?

If you have propane available you know you can store propane for years because it does not gum up, go bad, or pollute the air like gasoline does. 

You can use the 100# (24 gallon) cylinders, little bar-b-q grill type 20# cylinders, which is equivalent to 5 gallons of gasoline, or big tanks like 250, 500 and 1000 gallon ASME tanks.


Why use natural gas to power your generator?

If you have Natural gas available you would certainly agree that it is probably the most dependable fuel on earth and virtually an unlimited supply.  Natural gas is always there.  It does not gum up or go stale like gasoline. 


Here are many more of the benefits:

Propane and natural gas powered engines provide the same power as gasoline.

Longer, uninterrupted run times!

Connect to big tanks or to your natural gas (SNG) Gas Company pipe line.

Your generator will last longer because of larger fuel supply, and less running out, while under load.

Clean burning Alternate fuel will help extend the life of your engine life.

Eliminate the Dirty Port that gasoline carburetors have that shortens the life of an engine.
