Checking Residual Pressure
1 Connect as described in "Connection of pressure testing equipment". See: Connection of Pressure Testing Equipment
2 Start the fuel pump by setting the switch to the ON position. Read off the system pressure.
3 Stop the fuel pump by setting the switch to OFF. The pressure should now immediately drop 0.1
- 0.2 bar (1.4 - 2.8 psi).
4 If the residual pressure has dropped more than 0.7 bar after about 20 minutes, check the fuel pressure regulator and the fuel pump's non- return
valve for leakage.
