I am planning to run a gas line out to the back building on my property ( about 250') to operate a 75,000 btu furnace and a 12kw generator ( approx. 200,000btu). What size gas line should i install? will the gas pressure be sufficient?

    First you need to tell us the existing gas line size and the meter capacity, along with existing and capable pressure. I will warn you, with your requirements you will be surprised with the size required.

    The gas meter for the main house is rated at 1 million btu's and i am assuming at least 7" water column inside pressure

    No Problem

    Relatively speaking your line size would be 1 1/2" @ .3 pressure loss in inches of water. At .5 loss you could go to 300 feet, all being rated at 300M. That is with standard pipe. Check the charts of using Gas tight or similar products.
