Bigant Posted January 19, 2017 Share Posted January 19, 2017 Hi I have a 01 Discovery 2 TD5 and as we all know they are not the quietest running vehicle, however, the engine noise on my vehicle is drowned out by a high pitch whining which I am told is coming from the fuel pump? It is most noticeable when standing behind the vehicle and has got the point now when people know I am arriving as the can hear the whining above the engine noise! Anyone else encountered this, what is the fix? Bigant Quote Link to comment Share on other sites More sharing options...
sierrafery Posted January 20, 2017 Share Posted January 20, 2017 Hi, first of all put a new good brand fuel filter(Mahle, Coopers, Mann, etc) or genuine if you dont find it too expensive Quote Link to comment Share on other sites More sharing options...
Maverik Posted January 20, 2017 Share Posted January 20, 2017 The high pitch noise is often associated with the failure of the fuel pump that is located in the fuel tank, changing the fuel filter (if its not been done for a while) can alleviate the noise, but generally means its on its way out. A work colleague once put petrol in the tank, that made it squeal too, stopped when he topped it up with Diesel. Quote Link to comment Share on other sites More sharing options...
