I certainly don't have any interest in ordering and stocking spare parts that I will likely never use. I might change the primary filter once in the time I own a truck but it's unlikely I'll ever change the under hood filter.
When you buy the kit, it comes with both filters (You may be able to buy them individually, but I did not see that as an option when I ordered mine), so I don't know why you would not replace them together.
When I bought mine they came in kits as well but I don't change fuel filters unless i feel there is some reason to. So on one truck I changed the primary when I had a problem with the fuel gelling. Changing the primary was enough to get me going again. The other truck had its primary filter changed after putting DEF into the fuel tank. I disconnected the fuel line at the under hood filter and pumped all the fuel out of the truck through the low pressure side. After emptying the tank I changed the primary filter just to be sure I had gotten all the DEF out of the system. So far I haven't come across any need to change the fuel filter on my latest truck..... it only has about 25000 miles on it.
