Hi there I need to find out what size the thread is on a g13 block for the oil pressure switch


I'm fitting an oil pressure gauge and oil temperature guage and would like to know what size adaptor to buy

On eBay there is an 3 way adaptor that says it fits Japanese engines but am unsure



Thanks for any info on my query!!

Thanks Scottie can always rely on you and this forum for a quick answer!!!!!

Will be doing a 1.6 conversion soon so I'm sure ill need some advice from your stickies!!

While your there would you know the size thread of the standard 1.3 water temp sensor???

This is the Adapter you would need!

Im sure scottie and others can remember the thread about mine

depending what oil pressure sender you have it might be best to use one of the remote T-pieces, I can't use one of the normal ones as when its done up tight the oil pressure sender won't screw in as the oil filter is too close

Iirc the water temp sender is 1/8x28bsp

Ok mate thanks for the info!!!

Just a thought Im not sure if any good but I found on ebay Electric Oil Pressure gauge would these be easier to use ?????

The electric pressure gauges still need a t piece as the temperature sender is 1/8npt but the advantage of an electric one Is you don't have to run a copper capillary tube through which looks messy and is not very flexible. But I opted for this type as it was cheaper
