what gauge wire?

Hello everyone,

I'm still working on my electric fan conversion, and had a quick question.
The gauge of the main power lead that will come off of the battery or
starter is what I've heard a variety of answers to.  

My fan draws around 9 amps.  I've been told to run a 10 ga. red wire, while
others say 14 ga. is fine.      

I'm running this through an inline fuse and was going to use a 20 amp fuse,
but is that too much?

Opinions?

Thanks,
