Line replacement can be a tricky item to quote as they are for the most part all custom made. It also depends on where to and from you are replacing the lines. Some times you can patch a section in, others you need to replace from source to destination. It is best to have someone who is familiar with the repair to visually inspect and give you a proper quote rather than a guesstimate. Let us know if we can be of further help.
