2 micron fuel filter

[RM]

has any one seen this site for installing a cat 2 micron fuel filter on a duramax. i work for cat and they put 2 micron fuel filters only everything new now and send out a lot of information on how important to filter out down to 2 microns. they say that 5 micron particles are the ones doing all the wear. does anyone know what the pressure drop would be across a 2 micron filter as apposed to the 10 micron filter on our trucks? im betting that the lift pump couldnt take it. i see where the fass pump you could put a filter of 3 micron on it but paying 600 bucks for a filter seems expesive. especially something i could rig up my self if the pump could take it this is all just thinking out loud but heres the link look around also there looking for voluntiers to rig up a system for ctd http://www.nicktane.com/

That sounds cool and since Im only about an hour from sacramento maybe if I get some time I could make something happen. I just wonder how the filtration VS. flow is affected?

I've done quite a bit of research on this subject, but I'm no expert. I'd like to get a 2 micron filter (or even smaller), but there are really no convenient kits for the Cummins at this time. The FASS could work, but I agree that the price is a bit overwhelming. I've sort of resolved that I'll leave the fuel system alone until after the 100k warranty is up (no way my dealer would warranty anything with a FASS on it). Indeed, a supplemental pump would be required to push the fuel through that 2 micron filter.

 

[rbattelle]

One other thing: if you're going to run the 2 micron filter, do you need to provide a supplemental fuel heater to prevent it from freezing up?

I'm currently running a Frantz SUB-MICRON ( smaller than ONE micron!) fuel filter on my truck:

... fuel pressure at the volume used on my Cummins is about 3 PSI less than prior to installation, but still entirely adequate for my setup. If interested in more info,

nicktane.com is the owner of the Diesel Place website. Most of the Dmaxs over there are running a 2 micron filter either pre or post factory. A few of us are running either a 10 or 30 micron pre with a pusher pump to the factory filter followed by a 2 micron filter. No you don't have to worry about a 2 micron filter gelling at the tank.

Gary,

Since TP extracts water, is there not a concern about it freezing up in winter?

I installed a 2 micron stanadyne final filter in line with my oem filter on my TDI and had no restriction problems. I've told people about emulsifying fuel additives for a long time now. People that go to this type of setup will especially want to use them, since the CAT filters have no water separating ability.



I have a 2 micron Racor filter installed between my aux tank and main tank, and typically like to just fill the aux tank so all of my fuel is double filtered. As mentioned above, it's been said by engine manufacturers including Cummins - that particles as small as 5-7 microns are causing injection system wear. This becomes more important as rail and injector pressures increase - like the HPCR 3rd gen injection. .

"Gary,

Dunno - wasn't an issue in the area of California I was living until a few weeks ago - no freezing temps - but up here in colder eastern Oregon, will see what happens. I do regularly use Power Service fuel treatment - so that may head off such issues...

In my travels I am finding that those living in northern Alberta and British Columbia are having major lift pump problems. I lost mine in Whitecourt AB. The dealership there said that some are only getting 25K miles on a lift pump. They were surprised that I got 100K on mine. A friend of mine who transports on the same route as I has lost 3 in 150K miles (03 Dodge Cummins). He keeps a spare with him all the time. Federal Mogul, the manufacturer of the pump, has been doing studies on the fuel up there. Apparently, the fuel is being refined from tar sands. DC is requiring written proof that fuel filters are being changed per the manual before they cover the pump replacement with warranty. Also alarming, is the extremely high numbers of injector pump failures. They told me the GM is having the same problem but Ford is not.



I do know when I fuel in that area I loose power and fuel mileage (up to 2. 5 mpg); much like using winter #1 fuel.



As a result, I am going to put a Nicktane unit on my GM and Dodge. I have heard nothing but good things about them. I also try to avoid fueling in that area but that is not always possible.

 

[rbattelle]

I have been searching for a long time now for an affordable all-in-one filtration unit that includes:



-A pusher pump

-A fuel heater

-The ability to accept some sort of 2-micron filters



Well, there's the FASS; it has a heater and a nice pump but won't accept anything in the 2 micron range.

Then there's the Air Dog Fuel Preparator, but it only accepts it's own proprietary 6 micron filter.

Then there's the Nicktane unit, which accepts the 2 micron Cat filters but doesn't include a heater.

I had looked closely at the Racor units, but to do that I've got to get my own heater and my own pusher pump and manufacture my own system (which definetly has it's advantages). I guess I'm being a little lazy.

The other concern I have is mounting this system on my truck and having my dealer void any fuel system warranties. I know that officially it should not void any warranties, but they can always claim that you screwed something up when you installed it. I want to install it between the OEM filter and the fuel tank, so I retain the stock filter (but not lift pump).



And so I don't know what to do.

Here's a link to an article about diesel fuel quality by Caterpillar...

 

[wsteffes]

Ture or false, you tell me.

filters for FASS

Napa FIL1724 2 micron rating

Cim_tek 70213 3 micron rating

Fleetguard HF6604 3 micron rating



Most filters take out some to this range I would like to know to what %.

50%, 60%, 70%, 80%, 90%, or 99%.



Another question does a big honken fuel filter with a high flow rating thats

half used up filter better than a little clean filter if the micron ratings are

the same.

 

[LightmanE300]

You guys need to determine if those filters ratings are 'absolute' or 'nominal' . Absolute generally means the filter traps particulates in that size range on a single pass with 95% or greater efficiency. Nominal means that it catches 'most' particles in that size range, and the efficiency varies - typically about 50-60%.

 

[rbattelle]

Been doing a little research

I've decided I really like the FH230 on this page. along with the 2 micron filter P/N FS19766. 180 GPH capacity, integrated 12v heater, optional WIF sensor. All you need is to provide a pump...



2 micron. I assume it's absolute, as I believe all Fleetguard micron ratings are absolute. At least, that's what they imply in their FAQ's .

Racor Filters ?

 

[Roger rodbolt]

Fuel Preporator now offers a 2 micron Fleetguard Stratapore filter for the AirDog that is a spin on and retails for less then $20. We use a separate spin on water separator with high micron screen so that water freezing in the main filter is not an issue. The two micron filter is on the pressure side and you will see no pressure drop between normal filter changes. Fuel filters are rated using different methods, single pass, second pass, nominal, absolute, etc. With our high flow system that returns the bypass fuel to the tank and under normal driving conditions, the fuel in your tank is filtered several times before it passes throught the injection pump. This greatly enhances any filter's ability to remove small particles.

I think there is more to this filtering issue . Don't see how an injector is going to last as long with what we all have been hearing(even on the Duramax),without cleaner fuel. I'm having problems now and don't want to blame anything(BOSCH,DC,FUEL SUPPLIER,ETC),but , if I replace all the injectors ,there will be a upgraded fuel filter for sure.

 

[Sixpac2]

where is the info on the 2 micron fleetguard filter. When you go to there web site www.goairdog.com there is very little info. please post a better source of info if you have. thanks

 

[Yo Hoot]

None of these filters are absolute. If they were 2m absolute they would be the size of a gallon for proper flow.



I had a racor 690R2 micron on my DMax post OEM. The DMax has no lift pump. It relies on the first stage gear rotor of the Bosch CP3 pump to suck fue all the way from the tank. It sucked fuel through both of my filters for 70,000 miles and no problems... not the same filter cartridges mind you. . I did change them regularly.
