You had to pull the windshield to do the headliner?

This should not have made me laugh, yet here I am still laughing...

Then why would it be connected to the intake?

The reply to that text: “I said not contact me anymore you creep. I’m calling the cops and getting a restraining order.”

it does have a fluid reservoir, that middle white section has a fill/drain port. and i bet that cylinder is for filling it.  

Whatever it is I’m sure the fuel companies hate it.
