Oil pressure gauge fitting - Block thread size?

[Jackle]

I've got an oil pressure gauge to fit to my 325, just realised that I also need a t-piece in order to keep the oil pressure switch as well doh! Demon tweeks have t-pieces available, but what size is the thread on the block?

Also I've got an oil temp gauge, and I need a t-piece for that as well - I guess the easiest place to put that would be along the pipe to the oil cooler, but what size is the pipe - again needed to order a t-piece.

Thanks, is that for the oil pressure switch thread? Would M12x1.5 be the right size then?

yes mate it is for oil pressure switch and 12x1.5 is correct

Jackle, is this for the Audi VDO guages?

I've just bought a set of these and need to order the t-piece for the oil pressure sender. WHen you find the correct one could you please post up a link to the correct part at Demon Tweeks or wherever you get it so that I can order one.

I've already got the temp sender in my sump plug.

Adam, mine are a pair of LMA gauges from Demon Tweeks, the t-piece I expect I will buy will be this one
Hopefully it will do the job.

I was also going to get this adaptor to fit in one of the oil lines to the oil cooler for the temp gauge, but I don't know what size to order - any idea?
