I went to finish my bonaco lines to the brakes today... Everything from the pedals down has been great. Then I noticed that the Matco brakes take a -4 fitting (plans call for an AN822 elbow), however the B nut on the bonaco lines is a -6.

Anyone know the answer to this before I call them tomorrow?

I've seen alot of different combinations for brake hoses on RV's.
-3 to -4, -4 to -3, but not -4 to-6.
