If I recall correctly, the "piggy back" pump is for the hitch only. In a 656 or 666, the hitch pump adds to the main pump when the hitch is not in use, I don't think it does that on a 504. If I am wrong, someone will correct me! You lose about 3.5 gpm off the top of the main pump for power steering. 8.5 or 13.5 left for the remotes. You decide. If Allan in NE catches wind of this he will say put in the BIG one.
