no, i guess you can call it a stupid question, i do not understand the concept on the sending unit, my 68 coronet is having a fuel issue, and i have ruled out the fuel pump and fuel pump rod, i was told to replace the sending unit, fuel line from the tank and the tank to make sure this does not happen anymore, i thought the sending unit only purose is to show how much gas is in the tank?

The sending unit has a screen sock on the end at the bottom of the tank that can get gummed up, especially if the car has sat for a while. The pickup line, too, can become gunked up. Mine was in really bad shape when I got my car. It's an easy fix... also check to see that there are no major kinks or crimps in the metal lines.

Before you spend any $$ replacing anything, Diagnose it. Check the 2 sections of rubber fuel hose, 1 by the tank , and the other by the pump. Is the metal ground clamp over the rubber section by the tank? The sending unit is just a variable rheostat that should read about 15 ohms full and 85 empty, and the previously mentioned pickup tube and sock.
Take care, Rick 68 Coronet R/T 440 & 68 Charger 528 Hemi,and 5 Challengers! 6 cyl, 318, 360, 383, 451

Should be... you will be able to see the screen when you pull the sending unit. i just read through your other post. Pull your fuel pump and measure the rod like they were saying. It shouldn't have any mushrooming on it.
Back to the sending unit... pull it and look and see if it's gummed up. You can order new socks separately if that's all it is. It's also a good time to check your float, and you can order those separately also. Try for a metal one over a plastic.... but yours is probably good. Just check the pickup tube for gunk and inspect the lines near the sending unit on the car for kinks.
If you have a compressor, blow the hard line out from the front of the car to the back when the sending unit is out...
Your half-full filter looked normal, they usually run like that. If the car is losing fuel pressure, and the sending unit checks out... it's probably that mushroomed rod. or there might be a small inlet filter on the carb in the feed line? Some carbs have them, not sure about yours.
