This would be a 1976 model. ( The third digit is the year ) The Stens # 125-153 is for a 1-1/2" neck with a 7-7/8" tank depth. It was designed for Simplicity tractors. If your old unit is the same size it could work. Messick's shows a 723-0155 gas cap/gauge for a Cub Cadet priced @ $19.51. But it gives no detail as to size . The MTD part number 723-0155 is correct for your tractor but it is no longer available.Stens has a web sight that shows size information on the various units that they have. I had to modify the Stens 125-153 to make it work on an old Dynamark mower. I hope this information will be of some help. **Q: Do these keep working? I've bought two factory replacements and the float no longer floats after a few weeks.** A: Dry it out in the hot sun for a few days. If it is "waterlogged" with gas, the gas will evaporate and the float should shrivel up a lot. Even if it doesn't, the float will work for a short while as it is dry. If it does not, the gauge needle may be stuck or egged and wallowed out on it's mounting. I have had lots of trouble with old units or other brands, but no trouble with Stens replacements and have bought many. It could be a bad batch - contact Stens - they may want it back to investigate. **Q: Will this gauge work with a simplicity citation?** A: Not sure? We put it on a Simplicity Sovereign. Doesn't read quite to bottom of tank, but that helps me from running dry. **Q: Is it screw on or a baynoet type fitting?** A: Screw on type. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/13744718-stens-125-153-fuel-cap-replaces-with-gauge-simplicity-2171252sm](https://www.desertcart.us/products/13744718-stens-125-153-fuel-cap-replaces-with-gauge-simplicity-2171252sm) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-20*
