So, is this a quest to save some $$ by using oil filters in leu of fuel filters? I'm curious how it works out, specifically gallons of filtered fuel per dollar of filter. PLEASE keep me posted [img]/ubbthreads/images/graemlins/wink.gif[/img]

Well, stopped by the official "Wix dealer" here in the glorious Moscow, ID... and the folks there were nice enough to both say "*** are you trying to with this thing?" as well as spend about an hour with me looking through catalogs and figuring out the best approach.

Here is what I know... or at least what I think I know....

1) Hydraulic filters are very spendy... because they must be able to filter very high volumes of oil (like 40 gpm) at very high pressures. These filters can cost in the neighborhood of $50-60.

2) Fuel vs oil. Not too many oil filters have a solid micron ratings, and of those few that do, we didn't find one below about 10 microns (give or take.. nothing we found ever said "absolute micron rating"). My guess (and their guess) is that they really don't have a need to. Many/most fuel filters, however, have ratings all the way down to about 2 microns... but the fear we have is that they will plug way too quickly with the grease particles.

3) We found that the fuel filter for my 7.3 PSD only filters down to 10 microns... so even though I am planning on an FN74 system for my WVO conversion, which means that my grease will never run through the diesel fuel filter, it seems sorta unnessary to filter below what the dino-diesel filters down to (unless someone else here says different).

(What micron level are WVO folks out there filtering down to, anyway)?

That allows me room to play with oil filters... .not necessarily fuel filters... and the oil filters (generally) were a smidge cheaper.

That's what I know for now.
