By any chance, does anyone have any idea of how many Bar pressure /at what time duration, the Fuel System should hold. The FSM says a quick drop to -0- is indicative of a leak at the Fuel Pump, whereas, a slow leak is more likely the Seal in the Fuel Distributor Primary Pressure Regulator.


After about 5 hours, I'm down to about .8 Bar. Very Slowly.


Thanks!
