Just received a recall notice on LS460 '07 to replace fuel rails. Stated may take 7 hrs of labor. What is the story on this?

I had the recall done today. Lexus smithtown ny. brought the car in @ 9:00 and received a call @ 12:30 from sheila, my service rep that i could pick the car up after 2:00. The service @ this dealership is quite good. The car had a fulltank of gas and no gas odors that some replies stated . Car runs great. As for 7 hours of labor,, i dont thinks so. more like 3.5 to 4.

Nothing to worry about, just bring your car to dealer, they will do it for you. Actually, they replace the tube for gasoline tank so you can drive there with (almost) empty gas-tank to get a full tank free hihihi .
I did that long time ago for my LS460.
