I hear ya. Living here in salt country as well.
All of my lines are rusted right on the bend after the tank on my 04. The evap line is leaking out, and I get to breathe in fumes for 60 miles of driving to work every day.
Lines at the dealer cost $300, but my local guy says its about an hour labor to do them.
Honestly, I blame the freaking ethanol garbage. I'm sure salt plays a part, but my lines are mostly clean except for the tight bends and connections where they are rusting from the inside out. I've been putting Lucas ethanol treatment in with my fill ups, and I haven't lost the pressure lines yet. But I drive so much now that the gas hardly has any chance to collect moisture. It really stinks there aren't any ethanol free stations around here anymore. My car used to run so much better on pure gas than this blended crap. Once the last station I had around me made the switch, I noticed fuel lines in all my cars, and all my friends, parents cars starting to go bad really quick where there are bends or connections in the lines. Stupid petrol industry and E10. I curse that stuff every day.
Good luck with it. Hope you can get it fixed on the cheap.
