Hey guys, I feel like a moron, but I was in a hurry, so I might have just not found where I tucked the line, but here's my problem. I got done having my injectors rebuilt for my 86 z28 305 tpi, by Cruzin Performance, and finally managed to get them in today at work. Howeverm one vacuum line, the one that goes by the fuel pressure regulator, is missin. I know it's suppose to be the HVAC line, but my question is where did this line come out from? Somewhere in the firewall obviously. But what general area? I can't find where it went.
