I use Napa Gold or Motorcraft, same as Wix I believe.
I hear Donaldson has something that works, the price is very high, and I couldn’t tell for sure if they actually have something that works…
The larger oil filter for the 7.3 PSD is my preferred choice, I currently run that filter on both trucks
I have always used Napa fuel filters, I get an enormous discount and order the 3417 in half dozen batches, and order the 3811 two at a time. My 91 just has the 3417, and my 86 has a 3417 (OEM 7.3 IDI water separator, pre e pump) and a 3811 (OEM 6.9 fuel filter, post e pump). They are mounted with the e pump on the frame rail under the drivers seat on that truck, using the factory filter heads with some modifications to seal them up better.
Napa calls the 7.3 PSD oil filter 1734, which I always get backwards with the 7.3 IDI water separator, in their system as 3417. 1742 is the smaller IDI oil filter
