You cannot and should not try to read the resistance with power to the sender.
Pull the sender out and read the resistance with the float at the top and at the bottom.
Do you have a ground to the sender?

Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first.
Life was a little easier when I was just a wrench.

i ohmed the sender out of the fuel cell with the flost at top....0 ohms...bottom...0 ohms.....i used a jumper wire with aligator clips on each end....grounded good....

No need to ground it...if you have the sending unit out, just connect one lead of your ohm meter to the sending unit terminal and the other to the body (where it would ground)
If still zero both ways...sounds bad. As for knowing if they are still around, did you try a google search for them?
i looked at google and it dont look good....i guess the 8 1/2 will have to do......the ohms and volts coming from the gauge sounds right??

Sorry was out with my daughter…
It sounds like yours is bad. Just double check your ohm meter that you are using the correct scale.
As far as grounding I am not familiar with this brand tank you have and assuming it is plastic? And no foam inside right?

it show full when it was full... at 1/2 a tank it would show empty....new one coming so that should take care of that problem
Well that contradicts everything you said. You said you tested it at all levels and it was at zero. That means the gauge should stay at one end and not move.
I'm thinking you did not check the resistance correctly, or not telling us what you are doing correctly.
There is a posibility you have the wrong guage for the sending unit you are using. Or the otherway around.
If you are getting a new unit from ISSPRO I hope you did not get the RA9509-ISS as it is not the correct unit for the guage you indicated
http://www.isspro.com/proddetail.php?prod=RA9509-ISS
The only units I see is the 240 to 33 ohm listed, you mentioned you had a 73/12 ohm guage. So based on the catalog you should be getting a
RA9508-FORD
or
Ra9509-FORD
And these are special order items according to the catalog. Look at page 26 of the catalog.

since i"ve started with this fuel cell the sender hasnt worked right...... so i went with a auto meter gauge...73/12 ohm... so i pulled the sender and am getting o ohms on the sender with it hooked up power on no matter which way it is ,straight up and upside down....i take the positive side of wire reading off the unit and get .030 ohms key off.....key on i get 0 ohms...volts.. key on i get 4.56 volts..do you think the sender is bad and am i geting the right readings for ohms and volts on the wire going to the gauge??
..the sender is 9 1/2 inches long and jegs and summit has them but only 8 1/2 inches long....
If you are using foam you should not be using a sending unit with a arm as it will stick on the foam. Remove the foam if you are.

Sorry I hate to see people replace things before actually determining the cause of the problem. Hopefully everything will turn out ok in the end.  Do check the part with the ohm meter before you install it to make sure the values are correct for your guage. Use a stick or something to push the float (up/down)when testing.
