I do it several times per year.
Three rolls of steel tube from the auto parts store.
A flaring tool.
A hoist.

There are two ways to do this:
#1. Form fit the new line = $$$$$$$$ = Days
#2. Rough in the line and use P clips with new sheet metal screws to hold the new lines =four too six hours.

All people want #1. until they hear the $$$$$$$, then they go with #2. or patch it with gas hose.

NOTE:
I use hydraulic hose to patch diesel fuel tube, it fits tighter, seals better and never had one fail.
