Some of the later 80's carburetted 2.2's had a mechanical pump and a vapor seperator. We had one on an 87 2.2 L body. I've also seen them on Caravans and Voyagers equipped with 2.2's in 1987.
I had an old V8 with an electric fuel pump mod on a carbed setup. It was regulated at about 5-6 PSI and was wired to the coil + terminal. The regulator was simply a pressure switch. The moment the needle valve opened in the carb, the pump kicked on unti it reached 6 PSI. Then it shut off until the regulator saw about 4 PSI. Then it kicked back on. It was a very simple operation, but could only be used with a carb setup.
