im investigating lpg conversion for the pat, at this stage there isnt an approved setup for them, there are kits comming online for the cherokee and the 300c ill be talking with jeep as i understand the proccess for approval isnt cheap and it would need to be a sequential setup for the pat, i have a car runnin dual fuel and runs great with the way fuel prices are going i dont want to end up in a few years time with a nice garden ornament etc, cng is simmilar main difrence is the tank needs to be a higher pressure, as i get info ill update here.
