Jake, in case it was the hoses between the outlets and the 3PH cylinders you were asking about, here are my measurements:
Old hoses: From turn of 90* fitting to opposite connection at cylinders = +/-42"
New hoses: From tip of couplers to opposite end at cylinders = +/- 32"
As mentioned, something more like 26" or so would have been an adequate length for the new hoses after eliminating the 90* elbow. If you purchase 5' of hose you could have 2 x 30" with plenty to spare.
