I've been doing a lot of reading/searching here concerning the installation of an oil pressure gauge. This obviously includes installation of the requisite sender.
There is a LOT of information on this - especially the need to relocate the sender.
Some say the fitting on the motor is NPT. Some say it's M10x1.
Reputable voices and vendors with lots of experience are on both sides have ample evidence supporting their position.
So which is it?
Isn't the OEM sender M10x1? Period? Full stop? How did we get to NPT for this connection - are the threads just thaaaaaat close and it ends up working most/all of the time?
The last thing I want to do is do this install and end up with A: a leak and B: ruining the threads on the case.
My plans are to use the NLA 42 Draft Designs relocation block. Their supplied hose uses an adapter that is M10x1.
Their block has two M10x1 ports and one NPT.
NPT is for the aftermarket VDO sender and the OEM sender will go in one of the M10x1.
That tells me that the threads in the case are M10x1 - right?
