Turning the pump up has no effect on fuel mileage except - if you turn it too high - you'll get unburned fuel, black smoke, excessive heat, and lower mileage.
If you turn the pump up, and at the same time, find a way to use the extra fuel - like turbocharging, at least then you'll be getting extra power for the extra fuel use.
My 82 1/2 ton 4WD has a rare option package - at least I see it described that way whenever I see another one for sale anywhere. It has an aluminum four-speed manual trans - Muncie I think - and fourth gear is an overdrive. It's more of a car-type transmission, kind of looks similar to what's in my 65 SS Chevelle. It does NOT have a granny low-gear. The engine turns 1800 RPM at 65 miles per hour. If this was a 2WD, it could be a problem because of the high gearing. But, since it's 4WD, it has the dual-range transfer case that gives it a nice low range when needed.
For many diesel pickups, RPMs is everthing. Fuel efficiencly goes down very fast with higer speeds. With some trucks, mileage of 22 MPG at 65 goes down of 15 MPG at 75.
