I sold my Carver and have a trawler now, but thought I would lean on this community’s experts since I received so much great advice from folks her over the years.

I have a Seastar hydraulic steering system. I recently had a yard install an Auto Pilot. The tech had a lot of problems stopping leaks at the fittings. I checked today, and there is still two small leaks at the fittings in the lazarette.

The setup is this. I have 3/8” hydraulic lines coming from the helm. Two of them each attach to a 3/8” tee which the bottom of the tee attaches to the hose going to the ram. The other arm (top of the tee) goes into a 600 WOG valve. All of this was originally from the manufacturer. The other end of the valve is used to attach to the 3/8” Seastar hose to the pump.

The return line from the helm feeds into its own shutoff valve, and then a hose is attached to the pump return.

He also attempted to attach a Furuno SafeHelm2 between the starboard hose and the tee fitting. That leaked, he took it off, re-attached the hose to the tee and it remains uninstalled. He replaced the 600 WOG 3/8” valve with 1000 WOG 3/8” valves.

It is now weeping at the return valve on the pump side. It is also weeping between the starboard tee and the valve.

I have moved the boat to a new yard, and plan to order new fittings and replace the work the tech “completed”. I would like to order the fittings but am not sure what tee I need. I am attaching a picture of the original tee, original 3/8” valve, and 3/8” fitting. Or, alternatively, can I just tighten the offending connections? The sealant is gasoila soft set.

Sorry for the length but hope someone here can help. Any advice would be appreciated.
