I appreciate your feed back to help get this sending unit working , so I ll explain 1 more time in as detail as I can.
1 tank is new
2 sending unit is new
3 wires that connect to sending unit are new
4 wire that comes from gauge to new sending unit registers 30 ohms when checked
5 ground wire is grounded to underside of cab
6 red wire is connected to top of stud protruding from gas sending unit
7 green wire is attached to any of the 5 hold down screws to secure sending unit to top of tank.
8 when the gas sending unit is outside the tank and in upright position, with red wire secured to stud and holding the green wire and touching the top of sending unit I raise and lower the float arm with the key on the instrument gauge shows empty when float is all the way down and shows different levels of gas as I raise it up.
9 when installed in tank and wires are connected it reads slightly above empty when I turn the key to on position.
10. There is no corrosion as everything is new.
I tried with both cork and rubber gaskets and still come up empty no pun intended.
11with the key on and installing the sending unit I get a bump to about a quarter of a tank showing on gauge , I have at least 3/4 of a tank of gas.
12 so there it is in a nut shell
13. Installing a new unit in a new tank with new wires and gasket should have been a cake walk but no it's the nightmare of my week
