i'd say go for it. CNG at that price is a great way to reduce your fuel costs. you will lose a little power with propane or CNG either way, but if you run dual fuel (keep the gasoline system) then you won't effect your non-local drivability, plus you'll extent the range of the Jeep significantly.

The only drawback, is that the piston rings will not last as long with CNG.

Just a traveling cat in a tall black hat riding a goat. Nothing to see here.

I found a internet site called lincoln composits they are in nebraska and they make carbon fiber tanks for cng vehicles they are signifigently lighter than steel or aluminium tanks. They mount these tanks on the top of buses and they have a neet pic of about five six in. diameter five ft. long tanks that they have mounted under a roof rack. on a s.u.v.

I think I could fit a 15 in. diameter 30in. long 5.4 gallon tank in the trunk of my LJ. and then just use any number of reciever hitch or roof mounter racks to carry cargo.

Some idea's i was thinking about is finding maybe one or two smaller one and putting them in the rear cargo area of my wrangler with out taking the seat out. Also adding tanks on the back in like a fabed jerry can holder type thing. Maybe in between the front bumper and grill, to even some weight, like where you would put a winch. One last possibility I have considered is fab up a smaller gasoline tank to put in a different area and remove the stock gasoline tank and put a cng tank there.

I don't really know as of now, first I want to try to figure out tanks, because they are interchangeable. Mine main concerns are that I don't want to lose my rear seat, I don't want to put them on a rack on the top because I love to take the top off, and I really don't want stuff to look odd or ugly. So lol it's going to be hard with the limited amount of space in a wrangler. I would say an LJ wouldn't have nearly as much of a problem if you don't care to loose storage space. Just stack a couple on top of each other because I assume the LJ has more room in the back but never seen the inside of one so?

I seem to remember some discussion of adding aux. fuel tanks under the driver side floor pan where many put an air tank. I'm not sure how much room is down there, I know cng tank is bigger than a small air tank. Actually, if someone made an aux tank to fit there, you could put the cng tank where the OEM tank was.

Ok, this is where I read it: http://www.jeepsunlimited.com/forums...d.php?t=872127

Another option would be to maybe use a Genright stretch tank to make some extra room. Just throwing ideas out there...

So lets see.... 2200 to do the change over. 2 years to see the cost benefit from the price of the kit(I drive 30 miles a day in town). and when I looked on their sight I have only one dealer in town. Can this be filled at any LP gas station. Like the ones that fill your Barb-B-Que?
I had a father-In-Law do this to his farm PU a while back. He really likes it but the tank took up a 1/4 of the bed.

Are you talking about cng? Cng and lp is different, and you can also get a filling station in your house for cng since most homes use natural gas.

No I thought they were one in the same. The father-in-law had LP in the back of his truck. I had to fill it a few times. I also use a line going to my BBQ grill rather than the LP tanks. I only had to drill the jets out a little to get it to work. So whats the difference isn't LP a mixture of Propane and Butane (depending on the temp and time a year)? I'm a idiot so be genital.

natural gas is pumped straight from the ground and delivered to your house after being seperated from oil and the well head, and propane I think is a creation from natural gas. Not sure tho
