## Questions & Answers

**Q: i have a myd  older 1977 s mtd part number is 723-0155  will this cross and work do u know  mtd tractor is 146-990a**
A: Your Model # should be 146-990A. 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.
