Sending units for aftermarket gauges

[19stang66]

I am looking to get oil pressure and water temp gauges from summit. They are the Summit Racing brand ones. Here they are --> Water Temp Oil Pressure.
My question is, can I use my stocking sending units with these or do I need to get new ones? The only ones they have for the Summit brand gauges are sending units for digital gauges. I'd ask Summit, but since their tech department phone is always fricken busy, I can't. So does anyone know?

Your linked water-temp ad says it includes a sending unit. Its written right there in the description.

A mech OP gauge doesnt require a sending unit per se, just some fittings of the correct size. Its attached to your oil-pressure boss near the oil-filter.

Ok, I feel stupid now. Thanks. Can I just get the fittings from Menards or a hardware store?

I dont know what Menards is, but any NAPA or whatever has small brass pipe fittings, plus many times the gauge package itself will come with an assortment of compression fittings. Mix and match to suit.
