Bart, he says our truck didn’t have a tee fitting going into the block like the one at the lower right in your photo, so he took the oil line off the canister and hooked it directly into the pressure gauge with a fitting to get the reading.

Well hate to make so many "mounds" out of so many mole hills, but as Jerry said, you are new to the hobby....so.........yes he can Tee in a gauge there at the top hose inlet port. As in: inline, as Steve said. The motor is a full pressure oiling system motor (1959) as opposed to a bypass system. But the filters used are bypass type. There is a "restrictor" I believe necessary in the system. It seem that if there was no tee fitting down below, that the previous owner (PO) did not yet plumb the gauge in? Eventually the tee will go down below. Wait for verification/clarification of that info from others.
Restrictor size changed in 1959 and if a different head was used on a 59, their need to be the proper restrictor. We have to be careful with what you have. The missing tee may or may not signify an issue not address by PO.
