0 280 161 007 is Bosch fuel accumulator/pressure regulator that usually sits on Mercedes. Shouldn't be there on 930 CIS. That's something cobbled up. Remove it and try again. It seems that somebody was trying to make DIY fuel enrichment system using non-Porsche fuel parts. The nipple whould be connected to plenum and it should regulate the fuel pressure to 3 bar (or whatever it's made to)+plenum pressure.

I'm quite puzzled to what PO was trying to achieve by attaching it between WUR and fuel head? If there is no nipple attached to it, it will act like a 3 bar pressure limiter.

There is a big fuel accumulator on 930 CIS just besides fuel filter. It sits on drivers side of engine compartment. Is it there?
Thank you for your time,
