Is a 1966 4020 gas tractor Postive ground 12 volt?
Also I just installed a rebuilt carb and it seems like I am not getting gas to the carb would it be the fuel pump is bad??
 
Yes 12 V pos grd.

That fuel pump could be bad ? sometimes the check valves in them stop working. You might be able to pull it off and test it by seeing if it pumps one way and doesn't let anything back through the other way. Ours looked pretty old so I just replaced it as they weren't too much $$.

There is also a shut off at the bottom of the tank and a drain too. I'd open the drain and let some out to get rid of water and junk and check the shut off is turned on. You have to reach up through a small opening to get at it.
