First, I would drain that tank and blow out the fuel lines. If you still have the tank in the cab, and the original outlet valve, it’s easy to do. Crawl under the cab and you will see a valve and an 1/8” pipe plug that removes. Close the valve (disclaimer, if it’s not frozen), remove the pipe plug, reopen the valve and drain.

I would then open the carb and clean it out. Good luck!
