Steering line question

[Jrspawn]

Hello, I wanted to see if anyone knew what type of fitting Grady white uses on the hard tubing steering lines? I have a 2001 Marlin I'm adding autopilot to and before I crack the lines and make a mess I'm trying to get all the correct stuff ordered. Are the hard lines that thread on to the 90 degree fittings on the back of the helm a tube style compression or flare fitting? Thank you!

The type of fittings depends on the steering pump. There are different varieties and in some cases adaptors are needed to connect new lines to older systems.
So first step if possible is to determine the hydraulic steering make and model.
