OPERATION(1 ) When the engine is started. the PGi/t-Fl main relay actuates the fuel pump, and the motor turns togeth
impellers.
Differential pressure is generated by the numerous grooves around the impellers.
(2) Fuel entering the inlet porr flows inside the motor from the pumping chambe. and is forced through th
port via the check valve.
lf tuel flow is obstructed at the discharge side of the tuel line, the relief valve will open to bypass the
inlet port and prevent excessive fuel pressure.
(3) When the engine stops, the tuel pump stops automatically. However, a check valve closes by gravity t
