I should have been clearer, the different length filters have different #'s. And the Hoye filters I have ordered are intermediate size, in the three filter lengths I am familiar with.
What I read recently was complaints from Subaru owners that the shortest possible filter was fitted to the turbo version of an engine just to make some clearance, this obviously reduced filtration capacity and oil cooling for an engine that had been better protected with the prior filter spec. This led to a discussion where the most convincing argument to me was if you are using the modern longer oil change oils then the premium version of the largest filter that will fit, is preferable.
=====Here are notes from a text file I compiled from TBN posts long ago:=========
F14D uses the same oil filter as all the YM series.
NAPA 1064, 1334, 1344
Fram PH3593A
AC PF1127
Motorcraft FL810
STP S2808
SuperTech (Wal-Mart) ST2808
I also think the following will work:
Fram PH6811
Carquest 85334

On the internet oil discussion boards, relief valve and leakdown specs are argued endlessly. As I posted above I think these specs are irrelevant if you change your filter before it is plugged.
Micron size passed/blocked is relevant but I think our little engines around 1 liter size were designed with about the same lube specs as the 1.5 liter and up Japanese auto engines of the era, so a good filter spec'd for those autos should meet Yanmar specs.
