Hi, does anyone has any idea is the fuel pump for Nissan Sunny long life? I've tryed to change fuel filter, but unfortunately for my car fuel filter comes together with complete fuel pump, which is quiet costly. So since it comes with complete pump, I thought maybe it is longlife. Does anyone know what is the milege to change fuel filter/pump? Nissan Sunny 2005 SG, A/T, 2WD
