Having problems with your Chevrolet El Camino ?
I have a 1979 El Camino. I need to install a EGR valve. Can you tell me where the vacuum hose connects to from the EGR valve?
There should be a vacuum diagram under the hood but if it's gone the EGR hooks to the purple topped vacum port. I think that's the one on the thermostat housing, if I remember right. The other vacuum port should have a red and white restrictor valve in one of the lines and that is the wrong one. The other line from it goes to the bottom left on the carburator. If you don't have any of that stuff, and that's possible, then it needs to have manifold vacuum so hook it direct to the carb or the manifold on an available nipple. Hope this helps.
