So I've been crawling all over my truck trying to fix any air intrusion leaks on my "86" 6.9 f350 dually 4 door. Today while laying under the truck looking at the Fuel Tank Selector Valve (FTSV) I had a thought. Why couldn't I stick a line into the bottom of the rear tank and run it level up to the front tank which would put it about mid height or 7" up from the bottom of that tank. Then I could get rid of the FTSV and the two lines running back to the rear tank. I just hate the electronic valve, every time I'm in the middle of nowhere and I go to switch tanks I have a panic attack. I know someday it's not going to work, or it will run the return to the wrong tank. The fuel gauge likes to drop to empty at times and that gets your heart racing even though it's almost full, which is probably the sending unit. I'm all about simplicity, that's why I have an IDI. Why wouldn't it work?? Any ideas on how to get a fitting plumbed into the tanks, braze? rubber seal?
