loosen the fuel line and if fuel squirts forcefully out the pump should be good,but it's really hard to tell pressure wise if you have fuel injectors they need a specific pressure to run.

I am unsure if my fuel pump is out or if the fuel filter is clogged how can I tell?
If you hear the fuel pump running, then start by replacing the fuel filter. If you don't hear the pump, check the fuse. A fuel pressure test will verify if the pump is good or not. It can also be a fuel pump relay or in rare instances a defective ECU.
How to tell is its fuel filter or fuel pump?
If you turn on the ignition without starting the engine you should hear the fuel pump run for a few seconds. This is a good indication the fuel pump is good but not 100% positive. A bad fuel pump can run but not pump fuel. If you hear it for run for a few seconds just replace the fuel filter to make sure it is not clogged. If it still does not pump have a fuel pressure test run to verify the condition of the pump.
How can you tell if Chevy blazer fuel pump is good?
First make sure the fuse to the fuel pump is good then pull the fuel supply line to the carb and turn the key on and see if fuel pumps out (note: make sure you have a bucket the catch the fuel.) If fuel pumps out, the fuel pump is fine, if not than it may be bad.
How do you tell if the fuel pump is bad or if it is the fuel pump relay?
If you turn on the ignition key without starting the engine you should hear the fuel pump run for a few seconds. If you do not check the fuel pump fuse and replace the relay before proceeding. If the fuse is good and the relay is good then you know the pump is more than likely defective.
How do you tell if fuel pump relay is out?
The fuel pump will not come on. Of course this could be a blown fuse or the pump itself has failed. Check the fuse and if it is good then install a new relay to see if that solves the problem. If not the pump is bad.
