Fuel Pressure and Volume
The relationship of fuel pressure to volume is inversely
proportional. Simply stated, as fuel volume increases the pressure
will decrease. Fuel pumps are rated at free flow capability, with no
restrictions within the fuel system. In actual operating conditions
fuel pressure is affected by plumbing flow, devices such as
pressure regulators and filters, and the carburetor itself, causing a
loss of fuel volume and pressure. Also acceleration and other
G-forces affect fuel flow. Choose a fuel pump with adequate
capabilities to flow the volume of fuel you need, at the pressure
you need, taking into consideration these types of volume and
flow losses.
