I planned to check my oil pressure with a oil pressure tester but the gauge does not have an adaptor for the M10 x 1.25 thread used on the oil pressure switch.


Here is how I made one.


I purchased a cheap aftermarket sensor from ebay.





Cut off the end.





Ground the nut end flat.










Punched out the internals.








Lined up a M14 x 1.5 bolt that did fit the thread on my tester.





Then welded it up.





Then ground it down





And ready to go!





Will try it out next weekend.

 

Great lateral thinking!
