We've got a part rattling around in the engine bay which is not fastened down. It's got hoses into it, so it hasn't fallen off the car. What is this part, and what size fasteners attach it? We're missing both of them! We'll probably use a washer on the one broken flange attachment to hold that side down.
General orienting photo
Zoomed in photo. Part in question is the one with the broken flange. This is our only FI Fiat, so we can't check the fasteners from another car. The part has zero fasteners through it at the moment, despite what the angle of the photo shows. That bolt is not through this part.
