One Problem i am facing, When fuel tank is full, fuel gauge show full but on accelerating vehicle, its needle drop down even near to end, when i refill fuel, only 08 L required to tank for up level again, electrician says, it is due to change in fuel pump set, so we have to open fuel tank and check fuel sensor.
Actually my mechanic initially installed chinese fuel pump, but it stop working after a while, so he changed it again. so any guidance please.
