How much does it cost to replace my fuel lines from tank to filter without dropping the tank?

Hello, there are two concerns with your question. 1) If fuel lines are replaced, they're replaced however they have to be replaced. If it means lowering the fuel tank, then that's what has to happen. 2) Determining the cost of replacing fuel lines is difficult and must be quoted and estimated by the actual repair shop that will do the work. Seek the estimate of several shops near you for guidance. It's not a "published labor operation" that has a suggested labor time, as other repairs would have. Fuel lines are "actual time" repairs, and repair shops can give you an estimate, subject to fluctuation.
