We most certainly do. I have seen the water screen in the bottom of the oem filter. How well it works is up for debate but I do not think everyone can base that off of just your sample of fuel. Your sample of fuel was so bad to begin with. I would almost consider finding better fuel more important than trying to filter what you have. Don't get me wrong, I love this idea and will buy as soon as I know the water part is dealt with. Water, imho, is more damaging than anything else.

You need to go back and look at the test posting because you seem to forget that the fuel sample from the pump was excellent for cleaness, w/o water and 47 cetane, the water was from condensation in my tank and the fuel filter was not stopping the water and the filter was coming apart and putting trash into the IP & injectors to make a long story short.

Next time get the facts straight before opening mouth and looking foolish.

ON, was the fuel sample on the Jeep taken after the filter? Is the fuel coming out of the bleeder filtered?

Yes it was from the clean side of the filter. We pulled the clean side hose going to IP because we didn't want to risk using the bleed nipple at the time because we were not sure if it was from dirty side or clean side, so we didn't use the bleeder nipple.

The fuel was full of cellouse material, other junk and had water above tollerance limits, the water in fuel light has never come on, even now. Yes I'm still on the same filter because that filter had less the 500 miles on it at the time. Greg said to put a new one on, but I thought that the money would be wasted. I twould just be the same way in a few miles, and accomplish nothing.

That dang humidity you have there is killing you. We are bone dry out here. When we travel back to Missou in the summer, I sweat like a pig and my skin gets all greasy feeling. I guess it is trying to moisturize itself.

oldnavy · **Posted:** Wed Apr 25, 2007 10:54 am

Yup it is about humidity, runs 90%+ starting about this time of the year and stays in that range til about the middle of Sept in these parts. Sometimes when the temp is in the 70's and humidity 90% + it feels like you are breathin water when outside. That said if the fuel is tuned over enough it doesn't get high enough of an amount to really harm the engines fuel delivery system, we just don't drive enough to do that however. I will try to find a place to fit a water seperator later this summer after the wife starts driving the MB, at present it is gone all day and at night or on weekends I don't have the time to work on the rig.

Just for the record guys, the bleed screw is on the inlet (dirty) side of the filter.

Also for the record, in the original thread on this subject, it was mentioned that while not equipped with a WIF sensor/water drain, the Cat 2 micron filter did an excellent job on it's own stopping water. A real-life example of the Cat filter stopping water ingestion in a worst case scenario was related.

From what I've seen, the only reason a filter is listed either as a "fuel filter" or as a "fuel filter/water separator" is whether or not it physically has a drain at the bottom.

Also in the original thread, those of us who have rigged up a two filter setup detailed how we did it, if you simply insist on having a primary filter with a water drain ahead of the Cat filter.

What is the micron size of a molecule of water?

Is water an issue here?

Much, much, much less than a micron, but if it is absorbed or adsorbed by the filter media then it will stop a certain amt of water.

oldnavy · **Posted:** Wed Apr 25, 2007 11:56 am

No the real issue was the OEM filter was about 10 micron nominal/30 micron absolute and would pass too much (too lazy to go back and get figures) trash 10 micron or larger and that water would cause the filter to actually come apart and dump huge amounts of trash in the fuel.

Also as mentioned it would stop water, but does not have a drain, and if water is a problem you just remove the filter and dump water out and truck on down the road. But Greg is right water has never been a problem in the past, but dirt has been.

Do you know offhand if I could use a 1R0749? I have a ton of these but don't know the size/thread difference between the 0750.

It will only be absorbed by celleous/paper filter media and then that is where you can have a problem. Small continued amounts of water collects in the paper and eventually the paper breaks down dumping everything into the system, synthetic fiber filters do not absorb water and either passes it or holds it back depending on the tightness of the weave or in other words the micron filtering of the woven synthetic material also behind the collection of dirt in the filter. Water will not pass very well through this filter, if at all. I have seen a couple drained here at my GTG's and only one had any amount of water, but he was a home brew bio user.

The upper limits of water in fuel by ASTM standards you would never be able to see I have been told. Anyway I know the factory filter is almost worthless and that the water warning system is for huge amounts of water that could cause hydro locking, not the stuff we are talking about that would cause early wear on injectors way, way down the road. I had a retired JD tech tell me once that the best water detectors were designed to prevent hydro lock from water in the fuel in huge ammounts, not from condensation build up.

Not sure but I think its the same thread. But they are very large as you know and I doubt that you have room to get it in. Also that would be a lot of weight compared to the 750.

I think they are the same thread size, but not sure. But as sure as I say that I would be wrong. :roll:

CATCRD · **Posted:** Wed Apr 25, 2007 12:35 pm

Just found out they are the same thread and dia, but 0749 is a lot longer.

I wrote aDsorb. Look it up. Different meaning than aBsorb.

Sorry did't catch the spelling, too many misspelled word here.

adsorbed = accumulated on a surface of a solid

Hey I want to buy the adapter and a filter as soon as possible, just let me know when
available, I will order immediately, I need it to come in next week, will this be possible??

Old Navy- your right, I went back and checked,took me forever to find it! Any idea on price and availibility of adapter?

Have you placed your order yet? I am not sure you would be comfortable installing an untested product before leaving on a trip with the faimly, you probably would worry too much.

My test unit should be here tomorrow for me to install ASAP.

Is this in any way going to solve the air leak with the crappy head heater unit? :?:

IMO, no. Greg and Walt can correct me if I'm wrong, but this is just solely to allow you to use a Cat filter on the stock factory head. Fixing the air leaks is another whole can of worms.
