The heating element of my WUR is 20 ohms. Right in middle of range I think. (something such as 18-22 is acceptable?)

This morning at 65F/18.3C, my WUR is sitting at 26psi/1.79bar.
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.
