fuel pressure regulator
hi guys need some advice on my fuelab pressure reg that i have fitted
i have fitted this with paralell fuel rails an its all piped up corectly but noticed now as i have a defi fuel press guage and the one on the reg that when the ignition is turned off that the pressure drops off really quick and when the car is running theres an air sound coming from it , sounds like an air leak or bleed is this normal ?? the sound isnt constant it happens every few seconds or so

I had this happen with mine for about a week after fitting,it took alittle bit more cranking in the morning to get pressure before firing but after about a week it stopped dropping off so quickly and has been fine since.
That said fuel pressure should drop off but very slowly after turning the car off.
