I'm not sure what your fittings are like but the SAE fittings I use have the same internal bore for both 1/8 and 5/32 sizes. The excavator uses 5/32 hose and fittings but was restricted at every connection. I drilled out the fittings to match the inside diameter of the hose and the difference in speed was noticeable. I'm not saying it was an earth shattering change but it did help. Can't you swap the motor and spin the pump a bit quicker?
