This is the part:

It is the same across most of the Nissans of it's age.

It screws into the side of the oil filter block, look for a brassy/gold cylinder next to the oil filter with a big yellow plug you can't miss it.

On my ecr33 my pressure gauge was lazy and sometimes not reacting to revs or moving at all. I removed the sender, cleaned and fitted again (to different a block) and now it reads very close to my new defi gauge. Wouldnt count on it on a tuned engine (hence why I bought the defi) but seems I extended its life a bit

Is it easily accessible to replace ? Need a special tool or just slip a slim spanner onto the nut between the plug and the block ?

cheers

If you un-plug it you can get a socket/ring spanner over it - Take the filter off too for some more room.

There's not a whole lot of room so you'll have to be a little creative but it shouldn't be too difficult. Perhaps go from underneath if you can get the car up on some stands/wheels
