Re: Ford 641 Fuel Gauge and Sending Unit

jleonardwv,
If you want to test with out adding gas, you can put a hook on the end of a coat hanger (you know the ancient metal ones LOL!).
Put that hook thru the fill hole and catch the float. Pull up on the float and the needle should go to full. I made mine so I could push on the float to make it go to the bottom of the tank too.

I did that when I put a new float/sending unit in mine and I bent the arm on the float so that it read empty when it was empty and full when it is full.
The unit I had was for a 7000 and I put it in an old style 4000. The tanks have a very different shape. I got real close. A full tank reads 7/8 full.
The main one for me was that when it reads empty that it is close to empty, and it does that quite well.
HTH
