I have been putting this boat together all summer. Its been a pain in my ass getting the right parts. I need to know how these hoses are routed and the size of the fittings. I have a friend that works at a place that makes hoses aircraft-oilrig stuff, said to bring me fitting sizes and lengths and he'd make it happen.
In the pictures I have the steering cable and rod next to my oil/power steering cooler. Then my dirty ass pump..
Any help would be awesome.

Boat is a 1996 Velocity/Thoroughbred

oil cooler inlets are just like 3/8 barbed type ends

That steering setup is a brazil valve I dought you will find anyone with that
Hose end . Tried myself just buy the 2 hoses from mercruiser less than 200 for the set

5/8-18 inverted flare #6 I'm not sure on #1 & #2 I have a steering actuator in my shed ill look when I get home. Only two fitting are pressure the rest are suction...

the fitting going into the actuator is a gm metric style and has an o ring on it ,very tough to find
