1999 Merc 3.0. Original mech fuel pump.
In diagnosing a slight low power problem, i want to make sure the fuel pump is sending the correct amount to the carb. I’m going to take the fuel line from the carb, place it in a container and crank the motor over for 10, 20 secs or so. Is this the right way to go about this?
Also, my main question, how much fuel should I see once I do this?
Thanks fellas

I have no idea of the vol needed but the pressure should be 4-6 psi
