hi everyone. I have a 1991 Z28 with the 5.7L- box stock. Well, except for a cat back and some other incidental stuff...

i had had an engine fire that I managed to get out quickly, but I have to repair some stuff. The fire was at the schrieder valve on the fuel rail, so I’ve got some vacuum line damage, among other things.

if you have a similar set up, can you tell me where the vacuum line from the throttle body goes. Mine just ends under the plenum. I’ve looked at all sorts of diagrams on line, but none are clear enough to explain my particular set up.

thanks very much.

Thanks for the quick reply! Do you have a photo of the solenoid or a diagram that I can reference? Or perhaps someone has the plenum off theirs and can snap a photo?
