I have an 06 dually,Is there such a thing as a good filter "under 7 micron" that is not an after market setup. I plan on getting an after market, or better than stock filtration system down the road. Until then would like to protect my injectoin system as much as possible.Also will a stock in the tank pump work on an after market two filter setup?

Baldwin pf7977 i think that is the right number Here is my setup i built http://www.cumminsforum.com/forum/3rd-gen-powertrain/477364-my-2-micron-fuel-filter-setup.html

Wow nice pics, this looks like a great setup. I think i'll take u r advice and get the stuff that it comes with. Whats your thoughts on a stock lift pump

I have a 8 micron pre-filter and a 3 micron final filter on mine with the stock in-tank fuel pump with over 60k on it, and have no issues with fuel supply or pressure. So there would be no issue for now as long as you pump is in good shape.

I've got the GDP 2micron secondary FF kit installed on my '04.5; along with the 7micron Fleetguard in the OEM canister. There's a post here with pix of my set up.AH64IUD is the filter guru here.

The PF7977 from Baldwin is the best you can fit in the OEM housing, it's 5um absolute.

There is the filter god. I also fixed my messed up filter number in my first post. Gotta remember not to quote part numbers off the top of my head

One thing to remember too is when running fine micron filters 5um and smaller you will need to blend the fuel down sooner in the cold weather, I run straight #2 fuel with the fleetguard 7 mic down to 0*to10*f if it gets colder than 0*f sustained I will start putting 75% #2 and 25% #1 blended fuel and never anymore than that. Everyone with a Duramax that runs 5-2 micron filters will be stalled along the road with #2 at the same temps as the fuel is not gelled but is thickened to the point it can't flow through the filter fast enough to keep it running much past idle.I see them along the roads all the time around here.The HPFP 150 FASS I had on my 02 wasn't a fan of temps below zero either, always had issues with it wanting to pump my thick fuel when initially started when it sat outside in sub zero temps, usually let it idle for about 10 minutes an then shut it down and refired it and then it would build pressure. Sometimes it wouldn't even prime up during initial key on sometimes it would prime but extremely slowly.

If I'm seeing right, fm676 indicates he lives in 'land o lakes fl', I don't think it gets that cold there. But other than that I agree with ya.

The only time I have ever gelled was in my 20um filter, the 5um and 3um were fine. When the parafins gel they are larger than 20um. I wonder if the duramax has as good of fuel heater as our trucks? It also explains the FASS issue, no heater. Is the fuel in your area not winterized? The last place I filled up was already running a 10% #1 blend, plus additive. By the time the temps get down around 0 the mix is pretty close to 50:50, but advertised as #2.

There are a few places that sell "Winterized fuel" but most stations carry straight #2 year round, then depending on the station a 50/50 blend and then straight #1, a few actually have blender pumps which you can choose from straight #2 to straight #1 in 25% increments.

Yeah I don't know what the duramax guys have for heaters but they are always the first to drop in cold weather if not running a blend. They think they are gelled but don't understand the capability or lack there of for the filter to flow a fuel that is just starting to thicken but not actually be gelled yet. Most just throw 911 and new filters at them.

Had a young kid pull up to the pump opposite me at the station a couple days ago.............40*f and already looking for #1 fuel complaining how cold it is, I had to do a bit of educating at that point but I don't think he got it, looke dto be early 20's with a $70K all decked out lift kit ect ect ect powerstroke. all these young kids making good oil money right out of high school and don't know any better.:banghead:

lol...............I didn't see that but was just making a general comment anyhow.

Very interesting on the fuel, I thought it got COLD there. Everywhere I have bought fuel in the NW winterized at the pump. The only exceptions are a few stations I have seen in MT that offer 1, 2, and 50:50 year round.

Not everything sits outside, it is cold here that is why a lot have garages and or heated garages shops ect, this is a huge benefit, once the fuel starts circulating it warms the rest as well but leaving a building with warm fuel is already a big plus. Most will start to use a blend only when they start seeing issues from straight #2 not cutting it anymore and not a day sooner with the cost being so much higher.Mainly they let people be in control of what they put in the tanks yet versus just selling what they want you to buy.

The coldest I get is around 15 -20 in KY during hunting season

-20 in KY...........................Where????........................The BS-O-Meter is almost pegged!!! -20 with wind chill....................but straight air temp.................mucho doubtage here.

Pretty sure it is just a dash between the two numbers in place of the word "to" 15-20 or 15 to 20.

Ok now, ya'll been talking about normal diesel, grades 1 & 2. But with all this blending of 5% to what is the max sold normally now, 20% ??? Bio ... what does that change for Gel temp ? And is it still blended into #1 diesel ? (We only sell #2 year round here.)

Bio gel's much easier. The states that mandate B2-B5 only do so in warm months, from what I understand.

not -20..............15 to 20 above is the coldest I get so I think ill be ok

10-4. I actually misread you prior post. Sorry...............My speedreading skills are eroding!!

Well thank Y'all for responding....lots of good stuff ill be doing after I get my injectors back, didn't realize the time that would take!!!
