Yes, didn't work for me. I still got way to much
oil in my intake. I wound up using an air/
oil separator plumbed between the PVC valve and the under carb vac source. I should have a post here in the FE section with photos on what I did. I'm running a single 4 so I just mounted the separator on the rear of the intake, you'd probably have to mount one on the firewall something like the original's puke tank.
