The lines are always full of fuel.
I assumed as you that it shouldn't make a difference as fluids don't compress, but after doing some research, found the following:
Head loss is a measure of the reduction in the total head (sum of elevation head, velocity head and pressure head) of the fluid as it moves through a fluid system. This is unavoidable in real fluids.
The head loss for fluid flow is directly proportional to the length of the pipe, as flow rate increases the pressure will drop.
Taken from:
Lesson 7: Head Loss
**************
In general the flow of liquid along a pipe can be determined by the use of The Bernoulli Equation and the Continuity Equation. The former represents the conservation of energy, which in Newtonian fluids is either potential or kinetic energy, and the latter ensures that what goes into one end of a pipe must comes out at the other end. However as the flow moves down the pipe, losses due to friction between the moving liquid and the walls of pipe cause the pressure within the pipe to reduce with distance - this is known as head loss.
Note: Only Incompressible liquids are being considered

From what I can gather, timing and volume would be both thrown off with unequal length lines (a double whammy).
