That fuel selector valve is deffinately bad though. I filled both tanks and decided to drive on the rear one first. Ive been driving it since Monday with no problems. Today I smelled fuel so I took a look and noticed the truck was wet by the front tank door. I opened the door and started to loosen the cap and fuel started coming out. I guess the back tank overfilled the front. I may just change the rear one first and the selector valve and see what happens.
