wht is the front to rear fuel and brake lines and cost of replacement

This is a 'time and materials' job. It is hard to predict how much it will cost. The new lines have to be made from raw unformed lines, in most cases. Also the fittings may be very rusted on the calipers etc so they may be need ot be replaced as well. it could take a 1/2 day to a whole day to do it safely and correctly.
