Thanks! I just submitted the formI see you still have the old gas cap on it. I don't know if you knew or have been told yet, but IH recalled the gas caps over 40 years ago - they're not vented properly and can cause a fire by leaking onto hot engine parts. What's amazing is, you can still get the replacement safety gas cap, for free. Just fill in your personal information and your tractor's serial number (or engine number if your B's ID plate is missing or hard to read) and send it to here: International Harvester & Farmall Gasoline Fueled Tractor Gas Cap Recall I have got the replacement caps for all my Farmalls. Sometimes it may take a few weeks, but so far they sent me one for every one I requested. They will do this until the supply runs out. The new caps are vented better.
