Stripped threads on new regulator

Bought a holley fuel pressure regulator cuz I had problems with carbs runnin over, put the barbed fittings that came with regulator in but needed a 90 on the inlet so took fitting out, took a 1/2 drive rachet to get it out and threads came with it! WTH. Been over a yr since I bought it can't find rec't arghhh were these not the right fittings?
