The Stock SUs used a stock mechanical pump. They run on 3-4 PSI. Is this for a 280zx? You should include all info. If so, the EFI electric pump is over ten time to high a pressure. Either get a proper electric pump or a good regulator.

You could but the pressure is at least ten times too high. A fuel pressure regulator will be needed. Some regulators return unused fuel to the tank. This will work perfectly as you have a return line. Don't cheap out on a regulator.
