I purchased the #5401 oil drain valve at a power equipment dealer today, who said it would fit my B&S motor. After getting it home, it appears that the valve's male fitting is a 3/8" x 18 NPT. Unfortunately, the snowblower's drain plug hole is for a 1/4" x 18 NPT fitting. I don't want to add a 3/8" NPT female to 1/4" NPT female adapter, plus a 1/4" NPT pipe nipple just to make this valve work. Besides, an assembly like that would likely be 3.5-4" in length. So I'll put up with using the existing drain plug for oil changes. Bummer!
