Onan Generators

You can count on gasoline to let you down!

You can not depend on a gasoline powered emergency backup generator to run during a real emergency. When ice storms, hurricanes, tornadoes and all other disasters hit the first commodity to be hoarded is gasoline. Long lines and rationing are a common occurrence during many disasters. If not used often enough, gasoline will gum up the carburetor. Don't get caught with an engine that can't run or without fuel for your generator when you need it the most.

You have invested in a backup generator, now make sure it runs when you need it. Convert your Onan Generator to run on propane or natural gas.

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

Our do-it-yourself change over kits allow you to run your Onan gasoline generator on propane, natural gas, or all three. Propane and natural gas are truly a backup fuel for a backup generator. Your engine will last longer, start better in cold weather and even start next year when you go to use it in an emergency. The best part is, with one of our do-it-yourself kits you can change your engine from gasoline to propane or natural gas all by yourself.

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. Natural gas is always there. It does not gum up or go stale like gasoline.

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 little bar-b-q grill type cylinders or big tanks like 250, 500 and 1000 gallon ASME tanks.

Here are many more of the benefits, and they are overwhelming:
