Probably the rubber O-ring, that is on the side of the metering barrel, around
that steel clip at the metering slit, got sheared during assembly. Oil all the
O-rings before assembly. I put mine together 3-times before it worked for me.
I used a non-curing gasket paste on the steel diaphragm for sealing.
I also had the indentations on the steel diaphragm.
As for the low system pressure, have checked the performance of the pump,
volume and pressure, as described in the Bentley mnual?

Good luck, Peter
