Just wondered if anyone else has had this problem, i recently moved the battery to the back and shortly after this whistling noise started coming from the fuel pump, it changes tone from when at idle and when under load. just wondered if it could be an earthing problem or if its my pump on the way out?

Cheers

 

is it your oem fuel pump or is it an aftermarket? My friends warlbro 255lph is loud as hell all the time even with seats in you can hear it..Maybe running your wires opened a crevis a little more making the sound more noticeable?

 

i could barely hear my stock one with my rear seats removed. ive never had a problem and as far as i was concerned that it was normal. but mine was not that loud

 

Thats what makes it worse is that i have no back seats now and it is quite loud,
its have an oem fuel pump and its never made this noise before, is this a sign of its eventual downfall?
