R32 GTR Oil Sender?

[Mr R32 M-Spec]

Hello guys

QQ for you, my Oil pressure guage pretty much works when it wants too, then when its being mean scares the crap out of you by reading 0, I know the pumps good its just what i think a fair few of teh 89 guys have had

So for thsi oil sender, can you just replace it? where is it located and how much for antoher one.

if its cheaper to just get an aftermarket guage I will, but I'd rather just use teh stock in dash one rather then have excess guages(already got a pillar boost meter)

cheers
