When I used to fit one of them I used to attach the filter to the tube and then feed the tube from under the car (you'll only need to jack the passenger side front up) you do run the risk of them sucking up water though if you hit a large puddle so I only ran it in summer
I never took the battery out either I just undid the bolt holding the bracket (its to the front of the battery and holds the plate down) and slid the battery across toward the drivers a few inches, gives you enough to get the pipe in from underneath
