Based on the answer above, it is a 7.25 gpm pump at 3000 RPM. There are 231 cubic inches in a gallon so if we take 7.25 gallons times 231 we get a capacity of 1675 cubic inches at 3000 RPM. Then divide 1675 by 3000 RPM and we get a capacity of .56 cubic inches per rev. If you go to the Dynamic Fluid Components website
Dynamic Fluid Components, Inc. - F20 Hydraulic Gear Pump you will see that the GP-F20-10 has a capacity of .61 cubic inches/rev, which is close. Add a -P-C to the part number if you want clockwise rotation. These pumps are available online from Northern Tool.This series is SAE A2 standard flange which should match Borg Warner. Please verify all of my info as I am not an expert, I just went through looking for a replay event myself and had to discover this on my own so I wanted to give you a leg up. Dynamic has a PDF catalog page on these pumps that gives you all of the dimensions. Information at Northern is weak.
