Reducing the diameter of the fuel line (by putting a hose clamp around it)
will not reduce the pressure, it will only reduce the flow. Recall from
physics that hydrostatic pressure (or in this case "petrostatic"?) is equal
everywhere the fluid goes. Perhaps you were thinking about "force" which is
"pressure x area". Force can be changed by changing the area upon which the
pressure acts. Hydraulic systems (such as the brakes in your car) use this
principle. The force you apply to the brake pedal is converted to pressure
in the master cylinder. This pressure is then transmitted everywhere in your
brake system via the brake lines. Then, the pressure is converted to a very
high force by having the brake line pressure act upon the much larger area
of the wheel cylinder or disc cylinder.
