Power steering pressure line

Hello and thanks in advance for your time and help.

2002 Tundra sr5 access 4.7L 4x4

I replaced my power steering pump and also had to replace the high pressure line. I replaced the Valve Assembly Air Control-part number 17630-74010.

Putting the system back together and bleeding the lines I see fluid leaking from under the air control. I'm wondering if there is a torque specification or if there is a gasket or washer that is needed?

 

Isn't it a tapered thread? If brass just snug it a bit more.

 

Ok that worked. I didn't want to over tighten the bolt. That's what started the problem. I couldn't remove the union or banjo bolt because it was over tightened and had to cut the head of the bolt off.
