Oil Temp Sender Thread size? Puma

Hi folks;

Another question re fitting accessory gauges to my Defender Puma.

Does anyone know what adaptor I need to fit into the oil pressure port on the engine, so I can retain factory pressure info and fit a 1/4 oil temp probe?

? M10 ?

I purchased an SAAS 1/4 (Redarc oil temp sender) 1/8 mid port (factory oil pressure sender but 1/8 is too small so I need this size please) with 1/4 end thread.

I realise I can tell what size I need by disconnecting the factory sender and seeing if the 1/4 inch SAAS unit will fit the block, but If I can find out without spilling oil all over myself first (remember, open 1/8 mid port) I’d prefer to ask, and use what others recommend.

Thanks in advance and best wishes all.

Ken

Thank you.

Fantastic.
Thank you Martin.
I just need a 1/4 to 1/8 reducer for the centre port in the adaptor then.
Good on you.👍

Don’t you need a 1/4 - 1/4 - 1/4 t piece fitting?

Nothing you are trying to fit is 1/8

Hi mate.
No, as the threaded male end of the pictured fitting is 1/4 inch. It should fit the block.
The other end has the Redarc 1/4 inch temp sender fitted.
I need to fit a 1/4 inch to 1/8 reducer into the 1/8 centre port on the fitting so I can attach the factory 1/4 inch pressure sender.

You're quite right, I was thinking of it from the other end
