1 of the Fuel lines in between fuel cooler and fuel filter seem to have a leak. It's in the channel attached to the unibody. This a common problem or no? There's a blue plastic hose and a black one.

Make sure it's not an O-ring on the connector in the engine bay

I checked that out, when I looked to see where they came out in the engine bay. It was dry in that spot, thanks for the suggestion though!

Disconnect at the fuel cooler, plug and try to pull a vacuum in the engine bay. Should let you know if there is a leak.
