Let the system bleed for a few seconds. Check the system for leaks.
Check the adjustment pressure with a pump supply voltage higher than 12V.
Adjustment pressure = 300 ÷ 320KPa (3 ÷ 3,2 BAR).
The pressure regulator is working properly.
The pressure is too high.
Check the return duct for jams or bends.
Replace the pressure regulator
(see pressure regulator p. 75).
Adjustment pressure too low.
Enable the pump rotation. Use a pair of pliers with flat and long ends to close the return duct a few time

the hose supplied with the motorcycle)
Fuel pressure= > 300 KPa (3 BAR)
