I have went thru 10 + pages in the search and the sticky, etc, so I got few final ?s. I replaced my sending unit in April and it only lasted til now. I wana run a mechanical guage but hear of people puttin a tee in to also run factory guage. Thinkin a 100 psi is the way to go. Is the stock location 1/8 or 1/4 npt. NAPA says 1/8 but I think its 1/4. Anyone have a pic of how they ran both from a tee in the stock location? thanks for any help. Jeff

 

I am pretty sure they are 1/8 npt
