The whistle sound is generated by a "vent wistle or vent alarm" threaded into the tank at the other end of the vent pipe. **Q: hello my oil cap have the numbers 214 35 SA. will this cap fit, if not which cap do I need?** A: To be clear, this is a vent cap to vent a tank so the tank can breathe while you pump out of it. The connection is 1-1/4" NPT Female threads. The numbers you provided I do not recognize so I am not able to help you with whether you are thinking of a sealed cap to plug a fill opening or you meant a vent cap for the number comparison. **Q: Picture shows 2" model 4025, Description = 1 1/4" model 4023, which is correct?** A: The product is the model 4023, it is an 1-1/4" npt thread. the picture is wrong, from whomever set up these listings. They used the same picture for all. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect Whistle Cap Replacement *by J***N on March 12, 2025* Certainly!
