Fuel Pressure: Specifications

Fuel Line Pressure (Desired Value)
Relative 380 kPa
Absolute 480 kPa

Absolute pressure: Fuel pressure in fuel system + air pressure.
Relative pressure: Fuel pressure in fuel system.
The air pressure is approx. 100 kPa at sea level. VIDA measures the fuel pressure in absolute pressure. External pressure gauge (pressure gauge) measures the fuel pressure in relative pressure.
