Oil pressure sensor for gauge

Gained an old Smiths oil pressure gauge from a stage 1 V8, to fit in my 109.

Anyone know which sensor I need to make it work in a 19J engine? I believe the 90/110 had a pressure gauge as an option but don't know if it was the same.

This is what you need, I think. Ring Craddocks to confirm, Paddocks sell one too

Nice one! Presumably the Smiths gauge was the original and not aftermarket so that sensor would work.
Eventually I may fit a combined pressure/temperature gauge which are all mechanical so one less thing to worry about, but the one I have will do for now. Should stop me being paranoid about the 19J losing oil pressure as well.
