When I bought my truck I was in quite a rush. I was at an extremely busy dealership that specializes in CNG vehicles. People were buying them left and right and literally buying them after I had test drove the vehicle.

I bought a dedicated F250. I can't remember the tank capacity the salesman told me it had, but he said that I should easily get 225 miles -- as in that was his conservative guess. I can only get 200 miles on the highway. How do I find out how far I can go?

I don't know how to find out how much fuel I can put in there. How do I find out the capacity of the tank?

I noticed that my tank pressure is 3000 PSI, and sometimes the pump delivers more than that. To be safe, I always stop fueling at like 7 or 8 gallons. Even if I know the exact tank capacity, I have to wait until I'm 100% empty to fill to that amount. How do you top off the tank without damaging it?

I seem to get a disproportionate amount of milage per quarter of a tank. The first quarter of a tank is almost always gone after like 20 miles, the next after about 60-80, and so forth until it's empty. Why would that first quarter of a tank be consumed so quickly? Is it not really 'full' ?

I know there's tons of information on replacing tanks, but has anyone here done it successfully? Just a yes or no is what I'm looking for.

Thanks in advance.
