I managed to get both my oil and fuel secondary filter changed. Neither one is very easy to access, but after doing it once, it will be much easier the next time.
I removed the floor in the bedroom to access the top of the motor for the fuel filter and decided to also remove the section in the closet to make it easier and see how much work room there is for the fan area. To get the closet section loose, the sliding closet door base has to come out. It wasn't obvious at first, but after sitting in the closet, I saw the screws that hold it in. There are two screws on each side recessed on the back side of the wooden slide. They are pretty difficult to remove due to the tight area.
Didn't have anything to fit the fuel filter housing top, so I had to buy a 36mm socket that fits just right.
