Fitting PRC3122 Oil Pressure Gauge on 3.9. Need Sender?

As in title,

I'm looking to fit a Land Rover Oil Pressure Gauge (PRC3122) onto my Defender with a 3.9 V8.

Does anyone know what Pressure Sender I need for this gauge as they are usually gauge specific, or so i've always believed.

Do I need to contact smiths or are these fairly easy to get?

Just not sure what one I need.

Any advice would be much appreciated.

Thanks

James.

Cross ref the guage u have and it comes up with this Britcar (UK) Ltd > PRC4043 TRANSDUCER OIL PRESS 2.5-2.5TD DEF (G)

Hmmmm, reckon it would work on a V8? Cant see why not?
