[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.

Thankyou
