Oh,

Just realized a pattern tonight. When I've got a full or mostly full tank, the truck runs great. Just filled up with 14 gallons a while ago. Was running like a dog before I did. It seemed like the truck would run great for a few days then go down hill and back to its old ways. I never kept a lot of gas in it until I started breaking in the new engine. I also have an erratic tank sender...which usually doesn't work. I think I'm gonna go ahead and replace the sender and the pump while I'm in there.
