Low pressure test (generated by booster pump)
Connect tee Mot. 1311 -08 for connecting test pressure gauge Mot. 1311-01 or Mot. 1328 for downstream pressure measurement (S) fuel filter or high pressure pump inlet.
Switch on the low pressure fuel pump using the diagnostic tool or direct supply voltage (each time the card is placed in the reader in the 2nd fixed position, the low pressure pump is turned on for 30 seconds).
Check the pressure on the pressure gauge, which should be between 2.5-4 bar.
Checking the fuel supply (booster pump)
Turn on the priming pump, draining the fuel into a 2000 ml beaker. To turn on the pump, place the card in the reader in the 2nd fixed position. The pump will run for 30 seconds if the engine is not started.
The measured performance of the pump should be in the range of 80-100 l / h, no less.
Attention! Checking the pressure and performance of the injection pump is prohibited.
