Remove and replace OMP Oil Metering Pump Lines 90 NA S5
My brittle OMP lines need replacing. I have a stock 90 NA with Air Conditioning and Power Steering. What engine parts need to be removed to replace the lines? I am guessing the Upper Intake Manifold, the Air Pump, and possibly the Sway Bar. Are there common mistakes I should be aware of? Is there anything else I should repair or maintain while doing this job? I appreciate your feedback.

not sure the air pump needs to come off, but it would be easier with it out of the way

The FSM has you blow into the oil injectors to ensure the check valve works. Sure enough when I just did it I had a couple plugged. Worth looking at if you're gonna replace lines. Careful not to break the vacuum "spider" that connects to the top of each. if you do it's hard to find the same piece.
