I'm Lazy And Tired

I'm sure this has been answered but not feeling the urge to search on this. Perhaps you chaps can answer. About 90% on this.

Acquired a set of used Autometer electric water temp and oil pressure gauges. Came with the sending units but here's the rub.

Water sending unit came with the 1/8 NPT- pretty sure the stock size for the sending unit is 3/8 npt so I need to get a 1/8 to 3/8 NPT adapter? I'll relocate the stock sending unit to the thermostat housing.

I'd like to keep the stock oil pressure gauge working with a T fitting. Autometer sending unit thread is smaller then the stock oil sending unit piece coming out of the block that the stock sending unit screws into. Is the stock 1/8 or 1/4 npt. Anyone have a part #.

in case anyone else needs it

water temp is 3/8 NPT and needed a 1/8 to 3/8
Oil pressure sendinng extension is 1/4 npt and needed a 1/4 tee with a 1/4 to 1/8 npt reducer for the autometer sending unit

yep know that thanks- putting the stock one in the rear of the manifold... found this nifty little T fitting for the oil pressure sendor 1/4male x 1/4 female x 1/8 female NPT fitting for $12 bucks
