fuel pump wires come right through the well in the chassis opposite the pump where one can check and test..

So Ive got to order another fuel pump..possibly will now have full pressure operating since I purchased the car, its always felt weak by comparison to my previous E320, 94 sedan and the mileage is low which also may result from weak pressure..
