Here's a suggesion about your water pumps. Send your originals to Skip Haney and have them rebuilt. That way you get your originals back and no problems. He can be reached at 941-637-6698. Also, if you have not changed anything yet, get it running with the original equipment first before you start changing things. I find it much easier to change one thing at a time. That way if something doesn't work right you know where to look right away. Keep us posted.
