The Purolator L20051 is the filter I use and have been using in mine for 20 years and it fits and works perfect, so I don't understand. The L20051 is right at 4-3/4" high, 4" in diameter and the hole is just a little over 1/2 " in diameter.
After seeing this, I can see the Wix 51100 would not work, but that's the number Wix says in their catalog and on line.
One thing that is interesting is that the rubber gasket in almost all of the Purolator L20051's that I have bought are not the correct size for the cannister. Every now an then there is a good one. I just keep reusing the one that fits, but there is another solution for that too.
