Look in Rockauto. go in the emissions section.
They might not call it a vacuum amplifier.......

What is the year, series, engine size and transmission type?

Its 1978 f150 custom with the 400 motor and c6 tranny. Its also 4x4 with np205.

I was able to get one on eBay real similar to mine with the same ports and all. I received it today and installed it but I dont see my egr opening when I rev the engine. Should I be able to see my egr opening as I give it gas? Or will it only open upon driving?

EGR switches are also color coded for temperature. They will open at different temperatures.
