Always service from the low pressure side. I do recommend that you find a good shop to service this though. I did this type of work 20 years ago, and it really is better to let the pro's do it, unless you do that type of work.

If you follow the low (suction side)pressure line from the reciever/dryer to about middle way of the engine compartment that is where you should find it. You will probably have to feel for it. It is extremly difficult to see.
Be careful to not to cross thread on service port due to lack of clearance . If you E-series is equipped with a Leece-Neville alternater tie your service line up to keep it out of the alternater fan.
