Still working on new tractor

So I am still trying to get the temp sensor out of the new tractor.  Afraid that I may have to remove the radiator to get it out.  Also had a fuel issue yesterday where it acted like it was running out of fuel.  Dumped a whole can of fuel system cleaner in the and it did not have the same problem tonight.  I think I am still going to replace the fuel filter that was on it when I got it but the problem may have been just some bad gas.  We will see.
