2008 GranPrix fuel lines
 

anyone ever change them?
3.8 engine, the lines are starting to show some rust, I don't want to wait for them to split.:pontiac:

Ive had to take them off when doing an intake. Pretty simple. 4 10mm bolts disconnect fuel line and unplug injectors. Pull up on the rail(might be a little snug due to the o-rings). Swap over the injectors and reinstall.

thank you for the info, I guess I should of been more specific, I will be needing to change the lines that run under the car.
