So I picked up a used pump assembly from a wrecker and have that installed and working. I'm going to send the Pierburg pump back, but I'm wondering if it wasn't leaking from the internal hose. I was hoping that maybe not holding pressure would help with my slightly leaking injector/flooding after 2 or 3 days problem but it made no difference. The supplied clamp and line don't seem to work well together and looks almost like the line was distorted by the clamp to allow a bit of a leak. If I had more time and money I would probably eat the cost of the Pierburg (I had to pay 20 some dollars return shipping this time!) and take it apart to see if being so small it is maybe brushless ?? I now have a new BOSCH (TI) installed on the original hanger so that is what I'm going to use now (back to using the connector instead of direct wiring) with the used one as a spare.
