Fuel pressure regulator question....99 volvo v70xc

[abscate]

I think the last pic is the rollover valve, not an Intake air control valve. That’s seals up the Evap system in case you roll the car over like June does every once In a while. If the hoses on it are fat, like 1 cm thick, that’s Evap. A leak there, or a split can make a hissing noise , too.

Non turbo cars in 99 have an iac. Turbo cars in 99 do not, it’s built into the electronic throttle body system ( ETB, ETM, or ETS are all used to describe that)

Have you found the name of this plastic part. I broke mine and need to replace it. Can't find a part name or number anywhere.

Is there any part number on the plastic adapter block? There is an o-ring on the FPR, is thee a groove for one on the mounting location for the plastic adapter?
