Fuel Pump always humming - Toyota Yaris Forums

My phone was sadly stolen yesterday so I cannot take photos, but, I have found something yo'...

Coming back from work today my pump made its usual noise, very intermittently. I decided to just 'try' the China pump but upon removing the OEM one I found the o-ring was completely stuffed up somehow. It wasn't like this a few days ago when I first took it out which makes me wonder.. Maybe that is why it ran perfectly for 2 days before the noise returned? Did I install it wrong? I feel if I replace the o-ring and reinstall the OEM pump my problem will disappear! Apparently with a torn o-ring the pump sucks in air which can cause a noise. Do our pumps work like that?

Thanks guys, I will make a plan tomorrow to get an o-ring at Autozone. Will let you know how things go :D

EDIT: Online they reckon I must lube the orifice where the o-ring goes with petroleum jelly? Vaseline??
