two months ago i realised that when i turned at first position the key before start the engine the sound of the gas pump started geting louder and weer maybe like growling.First thing i did i replaced the fuel filter and then the gas pump as the noise is coming from its place.This growling hapens only at first start and when the engine hasn't run for half a day.Although everything seems to work fine the problem seems to deteriorate slowly by time and as always afraid about fuel matters i want to fix it.Thanks in advance for any input

have someone turn the vehicle on for you while you listen to the pump uncovered .. to verify it is from the pump .. it may be something near it vibrating

Thanks for your reply.The noise was indeed from the fuel pump(165 Euros) but unfortunately the noise was created by the fuel pressure regulator next to the fuel filter.I replaced it (65 euros) and the problem went away.
