63 dodge custom 880

I had my gas tank cleaned and lined. I have a new sending unit. I read ohms from the tank to the gage. I have ohms on all points on the gage. I tested the condenser with a ohm meter and I read nothen with the pos wire on the wire and the neg on the body of the condenser. I am guessing my condenser is bad but I can not find one.I need a working gas gage.
Can anyone help or point me in the right direction?
