If you maintain your filters and keep them clean so that fuel has no problem passing through them then you will not have a problem no matter how many you have. The problems start when they become clogged and you start restricting the fuel flow. Since the one in the tank is the hardest to get to, many people neglect it, even though it's your first line of defense. So it's really up to you. If you maintain your filters you'll be fine. If not then your engines performance will eventually suffer.

If God didn't have a purpose for us we wouldn't be here, so
Live simply, Love generously, Care deeply, Speak kindly.
(Leave the rest to God) 
Silence, in the face of evil, is itself evil. Not to speak is to speak, not to act is to act. God will not hold us guiltless.
