I believe the wiring is really thin and you would be better off running the pump off a battery tender cable (Sae plug) or installing a powerlet outlet somewhere.
^^^ This.
Don't do it. The fuse is there to protect the wiring. You'd be really pissed if you lit your bike on fire when you were trying to fix a flat tire.
Buy a battery tender cable and install it, leaving the end hanging out up front near your steering stem somewhere. You can use it to trickle charge the battery when/if you need to, and also to power your electric compressor when needed in an emergency. (I recommend running the bike when you do so the battery doesn't get depleted) I also use my tender cable to power my tank bag, which powers all the rest of my electronic gadgets. It gets a lot of use for a $6 cable.
