+rep for checking my info. link is a great ref too!
if thats the case:

15.5 amps for an 044
assuming run is 10 feet of 16ga, voltage drop might be 1.3V thats enough to drop rpms quite a bit I bet.
22ga would pull out 5+ volts!!!
10ga would pull .32 volts. and 8 ga .2v
/\ Thats some heavy ass power wire!
If you put the pump under the hood and kept the wire run to 5 feet, 16ga would only drop voltage .65v. Surge tank with intank pump for the win!
