The test is to hook up a pump to my car and run the pump for exactly 30 seconds. A good pump has to deliver 750 cc of gas in that amount of time.
Sound allright.

If it can't deliver 900 CC's of fuel in 23 seconds it is junk. That's it, not a goddamn drop less than 900 cubic centimeters.

I have to use the gas line and its rather messy as theres fuel flowing
for a few seconds before I jam on the pump.

The flow volume test that is outlined in the shop manuals measures the output at the fuel distributor head return line in a given time, NOT the volume that the pump displaces directly from it. The line size, line bends and other components in the system introduce restrictions that have to be taken into account.
