Dad's 92 no longer has the factory FFM. The PO was JD dealer, and now it has two box filters mounted on the firewall, pushing down on the clutch cylinder, so that setup won't stay. Here are the options i am thinking:

1) obtain a factory FFM from a junker truck and put it back stock

2) obtain from one of our vendors ( I think PMD cable) a kit that allows oem lines to stay OEM, but allows adaption to:
a) a FASS system
b) an Airdog system
above would be ran oem style, but with a relay, and a line straight to injection pump.

3) whatevery is suggested by viewers of this thread, feel free to post! thanks!
 
I would either adjust yours as mentioned, find a small racor to fit underhood, or if money allows, and you want to resolve once and for all any and all Lift pump issues, Airdog seems like a nice all in one unit.
 
My racor is not underhood. I have OEM mgr.

I agree with just relocating, or adjusting the JD filter setup so its not interfering with anything. Its already done, and as long as you can get filters for it no problem, its an improvement over factory I'd assume. Why go sideways with mods.... Sounds like a fuel perssure gague install would be easy on yours with the hosese already out of the valley. Just cut and T it.
 
the thing is the OEM is 10 micron, and I have looked into, and cannot find what the glass box filters are.

Plus, it is higher than OEM, so AFAIAC, it is working the LP harder.

And yes JD is john deere, as that is the piece of farm equip it was removed from, as there are traces of green paint.

In a separate thread, it was determined that the OEM was the same on all 6.5L TDs, so when i obtain a 94 or 95 truck to junk (direct swap motor for mine) I guess that will be swapped over, otherwise the dream is a FASS or an Airdog.

Thanks for the input everyone!
 
IMO,The JD filters are most likely better than OEM and have a bigger filter area,so they will be easyer on the LP than stock as they flow more.
 
X2 on modifying the current setup. JD filters are known to be some of the best, talk to anybody in the farming/construction industry. Most people running JD equipment, run the JD filters. Those glass ones are not as easy as some of the other setups offered, but they may also prove to be helpfull in finding debris/water in the fuel. Got any pics of this???
 
I disagree. Those JD filters were also used by Caterpiller on the 3208's . They suck bigtime for air leaks in the winter when the seals get cold. Trust me, this is something I know alot about. I want to remove it off My 87 Luiosville and put a Racor on to replace it. Either put the stock FFM back on which in most cases works just fine or do an Airdog. They really are a great system and I can tell you personally the customer service it topnotch. Pureflow does actually make a system for the 6.5 trucks and won't cost much more than a FFM and stock lift pump. JMHO. I really don't like those JD filters. We have problems with them at work as well on the 710 hoes' in the winter.They are not all that different than what GM used on the later 6.2s and I didn't like those either. As you can see in the pic the upper ports are just a flush o ringed fit. Not very good in extreme cold . This truck has givin me alot of problems with this as have many others.

There are a million John Deere engines out there running happely along yr after yr with these filters, I have them on a whaukesha engine as well,never no problem,and it gets here to below 48c in winter,now thats cold enough to freeze the balls off a brass monkey.:D
 
To each his own........never had, nor seen any problems with these style filters. We have them on a couple of our tractors and backhoes. Almost every JD tractor at the dairy farm my buddy owns runs these style filters, with the exception of the newer series. Now IMHO farming is one of the toughest enviroments for any piece of mechanical equipment or accesory. Between all the dust, vibration and continuous hours, id say that these filters are more than "field tested"
 
Only telling my experience. Had air in fuel problem and chased it back to the filter head. That pic is one of my Trucks. The only thing I am not sure of is if the JD has three tits. I know the cat version of it only has one which may be why they fail on the Cat application. We have two new JD710s that constantly lose prime in the winter months. We have to park them in the garage.
 
I have had a few glass ones leak where the glass meets the metal, but think they are a good filter set up. I like the glass ones because you can see what crud is in there and drain water if needed. You can mod the glass filter housing to accept the all metal filter, there is nub that needs to be ground down and you can use both filter styles, but the full metal ones were more expensive last I checked.
 
I know one thing that is for sure, its gonna get moved! It may be re-located just after the LP, keep it down low so it is eay to bleed. But i kinda agree w/ aces, it isn't the greatest thing in the world.

Airdog/FASS is a little spendy, so OEM is looking good.
