Fuel Pump

[Amm]

Got this bad buzzzzzing sound coming from my fuel tank. Only happens when i fill her up? Just thought it was the change over of different fuel brands...... BP Ultimate/ Vortex? Do i need a new pump

[(B1) MR_fanny]

is it a stocker? only when filling up? does it make that sound when you prime it everytime or just filling up which is quite strange. if it wasnt doing it before then first assumption is its on its last legs.

hopefully someone with more experience can shed some light

i think u got a bee trapped in there mate

yeah some more info on the pump..

im guessing its an aftermarket pump, and when your running low on fuel, the sound of it pumping or buzzing echos more in the emptier tank making it more audiable.

Fuel types arent going to change the sound

Yeah my intank 044 buzzes, it's their nature, does get noticably louder when the fuel is hot (long drives or stuck in traffic for a while).

Dude. When its full! Not empty....

Either way its wierd...when its full...you sure its not just in your head?!

the more a pump flows, the more vibration it will make, the louder it is from outside or in cabin.

if it annoys you now i reccoment NOT taking your rear seats out anytime soon

Thanks guys. its been like that for awhile now i got no idea on how to get to it either( PUMP) As i was the first owner in australia and it just came like that.

Like i said everytime the tank is full it does this how would i know that this is a aftermarket item or just needs a replacement?

Would be over the moon if it was aftermarket hahaha

a dyno will tell you if your fuel pump is not meeting the needs of your air to fuel ratio. otherwise if you start feeling fuel cuts through the rev range i'd start considering a new pump. but if not, you have nothing to worry.

Yeah actually it does stall a little then boost not much.... guess i do gotta get a new one and ideas?

[dmr]

when you say stall, do you mean splutter? it could also be boost cut.. either way get it checked out by a workshop.
