Hello Ryan, this is a photo of my water pump from a 1988 1= 3B ...  Jeff


All,
   
Can anyone point me towards the correct water pump? The on= e in the top of the photo is the correct one. The one on the bottom is obvi= ously incorrect. It's the second one we've ordered.
The first one that I ordered looked identical to my origin= al one.  However, when it arrived it was similar, but about 1/3 smalle= r than mine. When I ordered this second one we all (Carquest employees) pou= red over the pictures to make sure it was correct. When it arrived it had o= ne less bolt hole than the one in their pictures.
I have a Powersport 13B. Any ideas what pump they ran and = where a guy can order one

Thanks,
Ryan
