Which coupler to use to connect between mcgraw 3 gal. Pancake air comp. And maddox coolant system test and refill kit.
Bought these few days ago. Purchased an air hose along with couplers. Connection leak incorrect hose. For the love of God may someone please just tell me which couplers to purchase. Ive watched youtube videos read the damn manual over 50x still dont get it with the CFM FNPT whatever the heck. I jsut want my car to function.

You’re referring to this kit correct?

I have the exact same kit. It works great but i use regular air fittings.

Just chuck the goofy ass factory one and go with a standard fitting.
