Thanks for your help,I will plug one of the 3/16 ports and pick up adapter fittings so I can use my 1/4” lines front and rear. I read that with my proportioning valve supplemental residual pressure valves are not necessary, that the proportioning valve holds pressure for the rear brakes and also decreases the amount of pressure to the rear brakes to avoid “overwhelming“ them (my words, not mfg.) Your thoughts?
