What conditions are your fuel lines?

Just a WAG.
I've got 60 lbs pressure to the FI logs, the plugs aren't showing lean on any cylinders. The fuel lines are stainless hard pipe to the regulator.
Hopefully I will be doing some work on the car tonight.
I'm in the construction industry and we're slammed with work right now..... so it's been hard to do any wrenching this week.
Thanks for the ideas guys. I'm noting all of these for this weekend.
