Fiat 850 sport spider oil pressure sender

[hairgoneJohn]

Hi

I've just bought a 1973 Fiat 850 sport spider. The oil pressure gauge is not working. If I short the sender wire to earth I get max deflection on the gauge and so it seems the sender is the problem.
The gauge runs from 0-8 bar and the sender needs to have max resistance at min pressure and min resistance at max pressure.
Does anyone know the sender required and where to get it please?

thanks
Jonn

I'm sure you know, but will list them anyhow. mrfiat, c cobert fiat, Auto Ricambi, Midwest- Bayless Italian Auto, Historic Parts Cataloge. Just a few places not including in Europe. Your sending unit could be common to other models (like 124 Spider).
