Help! 4.3 Vortec RHD Vac connections - Aus/Jap owners?
 

Anyone else on here with a RHD 4.3 vortec Blazer/S10?

I replaced the fuel pressure regulator at the weekend and on reassembly I couldn't for the life of me remember where one of the vac connections went, or find the pipe that was connected to it...

On the LHD it's the connection that's the PCV. On the RHD it isn't, it goes somewhere else, only I cant remember where!

I've blocked it off for the time being, but I got P0171 and P0176 after a short drive, so I clearly have a vac leak.

This pic shows the connection on a LHD, its the large elbow labelled 2 and it's the PCV. On the RHD it goes somewhere else... anyone know where?!
