Looking for the fitting that goes on the back of a V8 for connecting both the oil pressure sensor and oil pressure switch. This would be for a truck with dash gauges and electric choke. See photo.

They used to sell them at the auto parts store in the same place they had gauges, but it's been a long time since I've seen that square-shape block fitting. I do have a similar block fitting that is used for adding a fuel pressure gauge, but the port size is much larger.

Home Depot has a variety of brass fittings that might work to put something together. However, I'm not sure they have the right threads and size, and the actual T shape might make it hard to get everything oriented. For example: https://www.homedepot.com/p/Everbilt-1-8-in-x-1-8-in-x-1-2-in-FIP-Brass-Tee-Fitting-802129/300096125

I think this is the kit I used to see in stores. https://www.ebay.com/itm/2959630538...J-whovUEfCA6Hxwu_Xqx06jei_shlqY0aAoPNEALw_wcB
Or this style might work. https://www.amazon.com/dp/B0B8XK29Y8/
