As a Example, take a 100 gallon Fish tank that has alot of water mass. Run a 1/4" diameter hose connected from the bottom of that tank up the side of it to the top.
Fill that 100 gallon Fish tank with alot of water mass and see what happens to the Low mass 1/4" column hose.
Will the Large Mass volume of the 100 gallon tank force water to gush out of the low mass 1/4: tube??
No, It will self level itself to the tanks water level. Why is that when you have that 100 Gallon mass? Fluid Dynamics!
Good example. Technically speaking, it's not fluid dynamics, that example is of Hydrostatics since the liquid isn't flowing. For all skeptics, check out equations 2 and 3 here: http://en.wikipedia.org/wiki/Hydrostatics

To answer your question about Volume. The Pump works against pressure not mass. With both pipes having the same PSI but different Diameters.
Once fuel starts moving, line friction comes into play. The Faster the fuel moves, the more line friction and the more pressure is created in the line. Smaller lines if to small for the pump will create more resistance to any pumps rated flow vs a bigger line.
The bigger lines extra fuel mass will have no effect on the pumps abilty to flow its rated Volume. To small a line or too many turns and orifices will. mike
Good post! This is what people should be concerned with AND THIS is where we're talking Fluid Dynamics.
