List,

In an effort to track down the issue with a non working fuel gauge, I
removed the sending unit from the tank today.  It has not worked in years
but I simply drove 100 miles and filled up to be safe.  Not knowing how deep
the tank was made me not quite trust the "dip stick" method of measuring.

On the bench, I put an ohm meter on the case and the terminal and got a low
reading (empty) of 2.5 ohms and high (full) reading of 86 ohms.  Does anyone
know if this is the correct range for the sending unit?  If not, how do I
adjust it and to get what readings.

Yes, the float is full of fuel.  I will drill a hole, drain it and then seal
the hole.  I will try placing it in a pot of hot water to see if I can find
the leak and if I do, I will solder that closed.  Or, what is the part
number for the Ford replacement float, if that is the better way to go.  If
the Ford float is not hollow plastic or metal and is something that will not
hold fuel, it makes sense to simply replace the float.  Which is better
repair or replace?

I will be sending the gauge and the sending unit in for rebuilding if the
gauge still reads empty after resolving the float issue.

What is the collective wisdom on this problem?

I also measured the depth of the tank and it is just over 5" from the lip of
the sender hole to the bottom of the tank.  This is an original tank and it
shows no or very little rust in it.  I guess I just jinxed myself and it
will now start to leak.

Thanks in advance for the knowledge.
