I went to
www.livebaitlarry.com and got a few pumps and a Perko intake strainer. I'm going to put an intake strainer in the bottom of the boat in the exact place Correct Craft puts them for the front tank. You must use 3M Marine Adhesive Sealant 5200 to seal around the intake and don't forget only stainless steels screws. You drill a 3/4" hole and that is it. Don't forget to use a brass gate valve. I'm going to use a Rule 1100 to fill with the scoop intake these work great. To drain I will use a Rule 1100 out the cooler outlet on the side of the boat. Who uses that as a cooler anyway?
Check out Skylon's locker sac for a sac good for doing this operation. I put the fill line in the front and the drain line in the back. It was designed for Nautique's locker.
Also, for a rear fill system you can run the vent lines from the rear tanks into some phat buddies and then run a vent line from the phat buddies to the vent port on the boat. Makes for an easy way to fill the rear sacs.
