1990 s10 2.5L Fuel pressure

I am troubleshooting some fuel issues. My injector wasnt spraying right, and sometimes it would drip instead of spray. I removed the throttle body and took my injector to the injector shop. It tested perfect, so Im pretty sure I have a low fuel pressure situation.

The fuel passages in the throttle body are flowing well, no blockage or varnish. I bought a new fuel filter, and I have my old fuel filter of. I wanted to see if I was getting fuel in the line before I installed the new pump so I turned the key to on and watched the open line. The fuel steadily poured out, but I was expecting it to spray out. Anyways, is there a pressure tester port somewhere in the fuel lines to hook up a simple pressure tester with?
