Walbro 255 fuel pump HELP NEEDED

[Got.Boost]

Hello everyone

I have got a Walbro 255 fuel pump in my Glanza but when I driving in a straight line it's fine nice and load just like the Walbro pumps are but when I go round a round about or something like that the pump goes quite and the pump has got loader over the last month

The pump has been in the car for about 5months

Can anyone help

Thanks

maby the whine is when its sucking fuel but when you go round a corner etc it doesnt have to suck so hard due to sloshish about ?

just a guess mate if it isnt causing any problems i wouldnt worry, maby take a look yourself see if anything visable on the pump ?

Try it with a full tank might be the pump running dry under roll conditions
