does anyone know what the thread size is for a 1978 with a 351w for the oil pressure sensor sender? Either the thread size or the npt size if that is applicable. Trying to take it from what it is to a 1/8 npt with a reducer for a gauge. Thanks in advance.
That's the extension screwed into the block. I don't know why he says to ditch it; I have one on Babe's engine, with the factory gauge sender, and it (knock on wood) doesn't leak.
You can run stock and mechanical gauges with this. https://www.ebay.com/itm/Ford-Mercu...ash=item2f10f46a48:g:qUsAAOSwzRlaMqqq&vxp=mtr
Quick question. If I remove the stock one and hook up a different one will the oil light in my dash be on continuously?
