In general- 'A Few Hours' is three, never more than four hours.
Additional Input
I think this answer depends on who says it and what is going on in the time they are gone.
* In dollars and sense a few is three, no more than three and a half. In a jar of marbles, a few is how many fit in your hand when you reach in and grab "a few."
* So, if your roommate says they are going for a walk, with their repeatedly broken off - not going to get back together, ex - boy/girl - friend and tells you; "I'll see you in a few." If 20 minutes goes by and they are not back, it is time to call and see if they are OK.
If your room mate is out with a new boy/girl friend and they are hanging out at a sports bar, watching a game and having some munchies. They may be gone four or five hours - without breaking the few hour rule.
If you are in a relationship with someone who repeatedly says "Oh, we'll be 'back in a few' and leaves you hanging for five or six hours. Or if you are involved with someone and at the end of the month when you always have to put in a few extra hours and every 20 minutes the phone rings and you know it will be this person, so you end up needing twice as much time as usual. A few can start to seem like an eternity.
* In black and white a few is three - four is really pushing it, but can you see where the exceptions come in? If you are with someone who can't do "a few" always set a specific time. It's not worth tossing a relationship over a few minutes unless the person is intentionally using semantics, to push your buttons.

No, the word "too" should have been coupled with the word "many" or "few"for instance to be used correctly in your sentence, resulting in, "too many hours", or "too few hours".
