This is on a 2012 XL Denali, 140K miles.
While replacing my upstream O2 sensors, I noticed a small amount of rust on the fuel line under the black plastic retainer that also secures the O2 sensor. Doesn't look too bad, but I have been debating replacing my fuel pump as preventive maintenance. In my prior experience with GM vehicles, these areas are prone to causing premature rust.
I may replace the fuel lines with it, they look to be one piece, how much of a pain are they? Looks like dropping the tank is the most tedius.
Any tips or tricks from people who have replaced them is welcome. Might not be enough rust to worry about, but I really don't want the lines to develop a pinhole on a road trip.
