Fleetguard filter naming code

If nothing else, you may get a chuckle for me being so dense and not realizing this. I found another post on this, but I was not aware of it so thought I would pass it along just in-case I am not the only person missing this little detail. The Cummins Parts guy explained to me that the first two letters on the Fleetguard number represents filter type.

FF - Fuel Filter
LF - Lube Filter
WF - Water/Coolant Filter

My wife says "it doesn't take me all day to look at a horseshoe!" I guess that could apply to me here. I didn't associate it.
