Hey people has any fitted a pw surge tank with a walbro 460 and got away with still using the stock reg on a fg?

You will find that the increased fuel flow will result in a significant increase in fuel pressure with the stock regulator.

You should change your fuel pressure regulator to bring the system down to 4 bar pressure.

High fuel pressures will lead to an inefficient fuel delivery system.
