Default WUR Rebuild

I sourced this WUR rebuild kit. It's for a non-vacuum WUR while the car has a double-vacuum system. Replacing the rubber diaphragm for the vacuum boost looked risky. What I wanted was the nickel-sized metal diaphragm and o-ring for it that actually regulate the pressure. Those plus the "8-shaped" o-ring. This was the cheapest way to get those although I didn't try just ordering those parts.

Went in fine and the car runs great. I tried measuring pressures but the Harbor Freight fuel pressure set was acting weird again. So I just hooked it up and ran it. Viola!
