Tri Fuel Generator Natural Gas Conversion Kits

Generator natural gas conversion kits

For the Natural Gas Conversion we used the Garretson KN 039-122 fuel controller
with manual primer for ease of starting. The KN fuel controller works great
with 11 inches of water column or 6 ounces of pressure as well as the typical
natural gas line pressure of 5 ounces. And the manual primer located in the
back cover of the Garretson KN 039-122 makes it much easier to start the engine
as it primes the carburetor with natural gas. The SD 073-321 with manual primer
can also be used for the generator natural gas conversion.
