Did you order the mount for the sensor and fuel lines?

Nope, do you happen to know part numbers? I figured the existing line brackets would work still.

Yeah I list the factory part numbers below but you need at least one bracket. There is a specific bracket that holds the sensor and bottom fuel line to the frame once you install the sensor. Without the sensor and bottom fuel like would be floating. Other than that I was going to order 4 or 5 fuel line clips just in case any break and it looks I may need an additional two once the new fuel lines and flex hoses are installed.

Keep us posted please. I've had to put my swap on hold until I pay for my spring semester.

I will keep you posted. My tuner (who is also doing the install) mentioned something about the fuel lines needing some tweaking (not sure if that is because I have a 5.3, will have to cross reference vs 6.2 part numbers).

Truck is at the tuner, he as the baseline and 91Oct tune and dyno completed. He is planning on the E85 tune/dyno tomorrow.

Sounds good. Let me know what your guy says about the tweaking. I'd like as much detail as possible.

Great numbers for the 5.3L! I can't imagine how my 6.2L will react to E85. When you get a moment let me know what your tuner said about the fuel lines.
