I have an ITA rx-7, 1st gen. I'm replacing all the plumbing from the fuel cell to the carb w/ 6an stainless braided lines w/ aluminum Aeroquip fittings. All is well but the in/out of the Nikki is made for a friction fit hose and clamp. Anyone know of a compression fitting or something similar that will give me a NPT thread?

 

I took a NPT fitting and soldered it on. It's worked for years...

 

IIRC, the thread/pitch is M12x 1,25 or 1,50
I used the fitting from either my Weber or the OER carb.
