That's what I thought and tried to do without the regulator. Unfortunately, the 1-4 lb pump pumps at 4 lbs and the carburetor float valve only handles 3½ lbs. So, I had to add the regulator, even for very brief use of the pump. Such brief use is usually not enough for me. I need at least a minute or two and usually longer, especially climbing mountains at high altitude, even in cool weather, the pump has to be run continuously.

I mounted my regulator in the frame rail just ahead of the pump.
