: Why would you want a replace a fuel line on a 55k miles car ??? No need unless they are leaking. If they have to open a fuel line to replace a valve cover gskt then a seals/gskt and labor should be in the valve cover gsk repair price. Anything they have open or take off should be included. They can't say for example a brake job is 10USD only but since we have to take the caliper off for this, the caliper removal is an extra 50USD ! I wouldn't pay for a fuel line replacement, but you know if they told you to do it, and you decline they will make it leak ! Just overtight a bolt and a seal will be destroyed. Take it to someplace else, and ask for a simple valve cover gskt replacement.
