Fuel line ???

[esff32]

I'm hoping someone can educate me. I have a Holley fuel pressure regulator that has 3/8" NPT ports on it. I'm assuming this refers to the orifice size, not the thread size. The 5/16" fuel line ff supplies has a thread size of 1/2"? I need an adapter to go from 3/8" NPT to 1/2" flare? I have looked all over for such an animal and it is not as easy to find as I thought.

I also would like to put a gauge on one side so I assume I would need a 3/8" to 1/8" 90.
Please educate me and point me in the right direction. Thanks for the help guys.
