So I was running my newly rebuilt 216 on my garage built engine stand, I hooked up an ammeter, voltmeter temperature gauge and an oil pressure gauge. All the gauges worked except the oil pressure. I have good oil to the rockers, but the gage doesn't move, I cracked the line to bleed out the air in the line, switched gauges, and still no movement. I disconnected the line going into the oil filter and hooked it to the gauge, still nothing, but oil would come out the fitting on the canister like it was being pushed out from the bottom of the canister and out the intake. I have the input to the canister connected to the port from the oil galley.This is the rearmost port. I am wondering if the tee fitting may be wrong or the size of the oil lines. I am using 1/4 " steel brake lines to hook this up and standard brass fittings from Home Depot to connect to the canister. Generally just hooking it up like I have for years.

What have I got wrong?
