Default fuel presure

The fuel presure on my gauge drops to zero when the engine is switch off is this normal or should it retain the presure.

Am not sure if there is a anti-syphon valve in the pump or if the fuel pressure regulator maybe leaking past. Hope it is not the injectors as this would wash any oil off the bores resulting in excessive wear.

Is it electrical?
If so, maybe it is wired to a circuit that is only live when ignition is on.
