Oil pump priming question

Does the oil come out of the oil pressure line, if you remove the gauge? No? check the next fitting closer to the engine. Keep going until you find the restriction. Or go to the auto parts store, and buy a whole new gauge, and tubing kit. Much cheaper than an engine.
Thats what I did, there was only small drops coming out of the tubing the goes into the oil gauge, but lots of oil coming form the engine into the oil gauge line. So I thought the oil gauge line was clogged up. So I bought a brand new copper line and the same thing is happening.
