I reused the factory lines. I had the intake side shortened by about 9in. and had a new fitting installed.
This is your standard 1/2" inline oiler with a k&N filter thats connecected to the intake line,
On the pressure line under the cab I have a check valve. Then on the first tank I have the water trap, tank pressure sending unit and the pressure switch.
Hope this helps a bit, anymore questions all you have to do is ask.
