I run the 51064 in all my diesels. Wix makes it for Napa but they take the 5 off of the Wix filter number.
Here is a screen shot from the Wix site.

It also says it's a lube/transmission filter....

I looked up my Kubota B7500 and it also says to use the 51064 on the engine. IDK but I guess I'll stick to using them.
