loosing boost cant work out where

Hi all I have a 2003 nissan patrol zd30 full Nads bigger intercooler oil catch ect ect. Driving car yesterday there seems to be less power. I have looked at my boost gauge and can see it doesn't hold boost and immediately drops down to 0 it does still boost but not as high so not thinking turbo I have put new clamps on pipes and checked hoses cant see anything letting pressure out or cracks/splits what would you say do next? could it be the turbo anyone had similar issues and have a starting point.

Also their seems to be like noise like a electric pump like sound very faint and only when car is running cuts in and out not sure if same issue however have only noticed it since this problem

disregard found issue a small crack in hose to needle valve all fixed

All good that you found it, was going to mention soapy solution.

yeah did that but it was inside the foam that covers the tube so couldn't see it

Nice find mate. A nice and cheap thing to fix as well.
