I have a 1991 560 SEL. There is a gas leak at one of the lines connected to the fuel pump. Car has (2 fuel pumps). Is it difficult or expensive to replace those lines?

Not difficult, You probably don't need a new fuel line. Replace the copper crush washers under the fitting. Always use new crush washers when disturbing a fuel connection such as replacing the fuel filter. If the line is at the output end of a pump, you should only drool a little bit of fuel but be careful.

there is a line that starts at the end of the second pump and wraps around the pumps and filter and then joins the main steel line going forward,this is a common failure and easily replaced.
