[DG] Autopilot EV-150 Type 1 hydraulic pump connectors leaking
I recently installed the EV-150 system on my boat and noticed the connectors on the pump are leaking.

My boat is a 2005 320 Searay Sundancer with a SeaStar Helm pump HH5741, non pressurized. I purchased SeaStar hydraulic hoses and a SeaStar pump fitting kit HF5501, which consists of T fittings and adapters for the hydraulic hoses to connect to the existing SeaStar helm pump and the raymarine autopilot pump.

All 3 adapters at the pump appear to be leaking.

The raymarine pump instructions strictly indicate not to use any thread sealant of any kind.

As you can see in the picture I even tried to re-use an o-ring from one of the pump plugs, but cannot tighten the adapter enough to seal the o-ring.

The brass adapters directly connected to the pump came with the pump along with o-rings, which are captured in the adapters. These adapters are 1/4" BSP to 1/4" NPT(F).

The next adapters connected to the brass adapters are from the SeaStar kit. These are Connector Fitting # 600602, 3/8" Tube (M) – 1/4" NPT (M).

Did I miss something, or is there something I can do to stop the leaking?

PS. I added a picture of the pump with the connectors and a picture of the fitting adapter kit to the post, but they do not seem to appear in the post. But they do appear in the attechment list of my draft.
