FuelMaker is the primary provider of CNG refueling appliances in the US (although I think some competition in this area would be good for them). FuelMaker has a number of fueling appliances, with Phill being advertised the most (however, I would consider and compare all of their units). Federal (and possibly state/local) incentives are available for the purchase of new equipment. FuelMaker's most common products are the following:

• Phill
• Single Compression Units
• Multiple Compression Units
• Phill vs. Single Compression Unit Comparison
