Return line kit / Fuel Tank pickup tube /Fuel tank filler tube

1. Have determined that I am getting air intrusion overnight due to the return lines and want to get a rebuild kit. Is this one I found on Amazon a good choice for my 90 F250 7.3 ?

2. When running on the rear tank my truck stalls out if I let the tank get below 1/2 tank. Am I correct to assume this means there is a hole in the fuel pickup tube that lets air in when I get down to 1/2 tank? What is the part called that I need to replace? Is it called the "Fuel Sender"?

3. When filling the rear tank of my truck with diesel the gas pump keeps shutting off as the fuel backs up as if it was full even though the tank is only at 3/4. I can get the tank full but it takes a long time of slowly filling. Is this a problem with the vent tube? Possible to replace just the vent tube or best to just buy a whole new filler tube for the tank?
Thanks,
Chris

Your's from Amazon or Rockauto is what you need. Look for free shipping.

Your problem in the tank is that your pickup screen has fallen off or disintegrated, requires that the tank has to be dropped to replace. It is not the sender as a whole. This is what you need to replace. They are all the same from 83 to 2016 IDI and Powerstroke. These are also available on Amazon, order both to save shipping. A dealer cost is around $50.

When replacing the return line injector hoses, caps and O'rings. Be sure and use plenty of Vasoline or most any kind of grease to lube to O'rings and caps. Install the 1st O'ring in the 1st groove, then roll the second O'ring over it to bottom groove. Cut hoses to length so they don't push the caps or they might leak.

The vent on top of the tank can get plugged by insects "spiders". Search for what is called the "HUTCH Mod", to relieve the tank air.
Yeah, the Harpoon Mod. Had a brain fart.
