I agree they don't make sense, which is why I'm coming for help. But trust me, it does run. I can upload a vid at some point. I have not yet taken a pic of the gauge connections, but the valve is certainly in the right position, downstream of the limb to the gauge, otherwise my pressures would be backwards and go to zero when the valve is closed instead of the other way around. I tested the gauge and it seems to be accurate. The brand is Betooll (from Amazon), which I've seen recommended here at least once. I purged the system of air, but it made little difference. There is no change in results with plugging or unplugging the WUR.

I have not messed with the oil breather hose since acquiring the car. Charcoal canister connection is fine.

Fuel delivery should be good. I measure 3L/min going into the fuel accumulator.
