if thats all u got. then ya use it...no sense in buying another pumphead. but ifu have a #9 lying around it will work a lil better with a lower voltage...but since your running low voltage anyways its not like your trying to hop...so if u got a #11 and thats all u got then use it. u dont need to buy another pumphead
