warm up regulator ??
 

I used to have cold start problem with my 85 380sl.I replaced the OVP relay and solve that problem. Now I have a warm start problem.. I am checking the The warm up compensator or regulator. I notice it has a electrical connection and 2 inlets for fuel line. The vaccum line is not hook up to anything. Is it suppose to be like that? I didn't see any loose vaccum line anywhere..
