After looking at using the high flow 90 degree bulkheads for dip tubes I have decided to use them for everything but the dip tube in the MLT.  In order to assure clearance with my false bottom I am using a 5/8″ compression fitting bulkhead with 5/8″ dip tube.  The dip tube will be easier to cut to size then the high flow 90 and the 5/8″ size will make sure I don’t have any restrictions in the critical area before the wort pump.
