I sure hope that's not the case. I purchased a new K30 in 1986. 454 and the last yr for a carb. It got atrocious mileage. The following year a friend bought an 87 V30 crew cab. TBI 454 and her mileage was half again better than mine. If this doesn't help, I may return it to dual tanks, as it is, the right side tank was removed to make place for a large under bed box.Fuel mileage will probably still suck with the TBI but it will start easier. Glad you made it back safe Kenny.
