This is with 15 inHg pulled with my Mitivac on the WUR.
Fully warmed up, my fuel pressure is 46psi.
My 81 SC is a US delivered, still have O2 sensor and computer working.
I believe it should have a WUR ending p/n 090. But mine is a 089 with a vacuum port.
As I have said, this thing runs fabulously cold, warming up, and when fully warmed. When restarted while still warm/hot, it hits/runs immediately.
What I don’t have a record of is where my cold WUR pressure was prior to messing with it a month ago. I thought it was in my records from when I rebuilt the WUR a few years ago, but it isn’t.

Charles,
You have the
WRONG WUR. Using WUR-089 will not prevent it from running but your enrichment management would be severely compromised. Try finding a good WUR-090 and experience how a properly sorted SC CIS performs on the road.
If you are interested, I could lend you a WUR-090 that you could test on your car without any obligation to purchase. Send it back to me when you are done with the test.
