6V92 stalled - need advice asap

The Fleetguard filters have several times the filtering area of the Racor.

The Racor is a simple pleated media (and not very deep on the pleats either.) The Fleetguard is a combination depth+areal filter, and holds a LOT more crap before it gets plugged up.

Its a totally different design for the media; that is what accounts for the additional capacity.

The Athens system is also a 2-stage design with a bulk 30 micron separator in front of the Stratopore system. That setup meets common rail requirements (which require MUCH more stringent filtering than the old-tech Detroits to avoid injector and high-pressure pump damage) where the Racor isn't even in the same league and does NOT meet the requirements of the newer engines standing alone.

The Racor design was good 20 years ago but filtration technology has improved. The newer setup is also smaller and easier to service.

Is there any down side to using a 2 micron Racor on DD's? Most of us trawler owners did that, but fuel flows were much lower.

The flow rate is the same on the 2,10 or30 mic when new. The difference is the coarser filter lets more through and lasts longer, however the crap that passed through goes to the sec filter. I use 10 mic on almost everything and it is a good trade off. If fuel is clean use a 2 mic. Whatever filter you use watch the vacuum gauge, that will tell you when they are getting fouled.

Using 2 micons on the primaries is alot of work. Granted if your not running the boat much then using 2's saves you from changing the primary occassionally. 10's or 20's keep most of the junk out of the seconds.
DD's will run fine on just about any filter system if they are run, the problem is that if the boat is not used frequently, or the fuel is really bad. For the most part alot of crap that gets thru the filters like alge gets burned anyway. Generally the problem is air and many times its the filter o-rings or the top on filter is just not tight . KISS is usually rule in terms of diagnosis.

Guys there is NO 20 micron Racor. They are 2,10 and 30 mic. 2020SM brown =2mic. 2020 TM blue is 10 mic. 2020 PM red is 30 mic. The 30 will plug the secondary before the primary. Your call......

I have New John Derere engine's well about 2 years old now. I added the double 1000 reaco's 30 m.---- on the engine's there's a 10m. and inside that is a 2m. I thought of changing the 30 to 10 or 20 M. but thought it might strain the fuel pump. What do you guys think should I leave well enough alone? I only put about 100 hours a year or less on the engine's.

Put 2 micron filters in the Racors and add the vac guages if you don't have them. I run 2 micron filters in my Racors and I run the OEM secondaries at 7 micron(?). I don't put any cartridge at all in the on-engine primaries as they would serve no purpose. In fact, the only reason I run the OEM secondaries is to catch parts of the fuel pump should it decide to self-destruct for some reason.

I now have 200+ miles on the new starboard filters and 1200 on the port ones which seem fine. Today we ran out of Hampton Roads into 5-6' seas to stirr things up but it was A-OK. We continued for several hours in 3-4 and then 2-223' seas for many hours. Seems strange that just one side had a problem when both draw from the same tank. But I'm not complaining.
