On my later KE-3 fuel head there is a 8mm test port on the lower chamber and I've also removed the cold start circuit so am using the upper central port to monitor system pressure. Both ports are M8x1 so I machined the 1/8 NPT sensor thread down to M8x1 to fit the sensors without an adapter.
The alloy Lambda head I have here has a test port on the top system pressure gallery that feeds the cold start injector but nothing dedicated on the lower chamber.
Looks familiar, had Len (BoxterGT) build mine then added a gauge.
