What happened to the original pump? Do you still have it? Three main leak paths on the original ZF pump:
1. Rear cover thin mylar gasket - defies reason why they used that POS but causes 90% of leaks
2. Cracked rear cover - thin aluminum cover is known to crack if not tightened slowly and evenly. Maybe 5% of leaks.
3. High pressure hose o-ring at the pump. 3% of leaks
4. Front shaft seal - never fails until the front bearing fails (sealed bearing) which does not happen until north of 200k miles. Maybe 2% of leaks.
I can walk you through the rebuild if you still have your old pump.

Thanks for the tip @gulfstream69xr7 , I checked this and it was even worse with the pulley flipped. I wasn't able to get a refund on the pump since I ran it for several months but they are going to send me a replacement. Hopefully that solves this problem for good.
