The way we ran a fuel pump volume test was shut the car off, remove the fuel line, hook up a hose to the line, run the hose to a container and start and run the engine at idle for 10-15 seconds or until it run the carb dry and quits. Then see how much fuel you pumped. I have seen pumps put out pressure but little volume. Not likely with a new pump, unless there is trouble with the line to the tank. Jay6155
