What brand of 1 3/4" Hose do you use? It matters, maybe WAY more than you think.
Certain brands of 1 3/4" hose are actually more like 1.85" or more diameter, resulting in greater flow efficiency. This is good, but results in lines being drastically over pumped in some cases.
Ponn Conquest, for example, has a pressure loss of 19 PSI per 100 feet compares to 35 PSI in standard rubber lined hose. It's because it isn't truly 1 3/4" Hose. Heres a link to Ponn's Data,

Be aware when you buy hose what the performance data is, and make sure your drivers know. You can get pocket cards from All American Hose (the parent company of Ponn) that reflect the flows for their hose.
Stay safe.
