I am looking at Fass Diesel Fuel Systems for my 22 Ram 3500 HO Cummins, my truck has little over 7,500 miles on it and the fuel filter lift has 39% left and it has been dropping weekly. My question is has anyone have put one on there truck has had any issues / problems with there truck after adding the Fass Diesel Fuel System. The Fass Diesel Fuel System part number I am looking at is TS D07 100G.

Also I am trying to leave the truck mostly stock because I tow a 34 foot heavy 5th toyhauler 13.4 feet tall, I do have Banks Power PedalMonster and Idash DataMonster.

I wouldn’t. The factory system is excellent filtration and reliability has been very high. Fass has had its issues over the years as far as reliability. There’s always a concern your fuel injection warranty could be compromised as well by changing how it’s filtered and supplied pressure.
 
FASS is junk unless you need extra fuel due to upgrades the OEM is far superior.
 
From what I've seen, our fuel filters are more than adequate for the factory fuel system
 
I would stick with the OEM as well so long as the truck is under warranty and you have no need for modified flow. I don't see any reason to save money here for the extent of the warranty. Now, once the 100K powertrain warranty is up then I'd consider going with OE to maybe save a few bucks. But generally its not worth it to save money on filters unless its proven their is a superior filter for the price. I also am not a big fan of after market performance enhancing air filters either. They generally achieve their higher flow by reducing filtration, which decreases engine and oil life.
 
I've seen more issues from aftermarket fuel systems then from the factory. The factory filters excellent and it's not worth throwing away your warranty (and money) to change it out.

Honestly the only kit I'm a fan of is the Thorttle Up that adds the Cat Advanced HE filter after the stock water seperator and before the Nanonet on the block. Most folks DO NOT need this setup at all, but if you're stuck with poor fuel quality in your area and seeing the engine mounted nanonet get nasty quickly it can make maintenance easier allowing you to get the full 15K miles out of the Nanonet. 99% of folks buying commercial diesel will not have this problem at all, but I've seen it with fleet trucks operating in remote areas where the only fuel you can get can be sketchy at times.

I tend to avoid companies that claim the 1R-0750 is the best filter that you can buy.... It means they have done no research and are using specs/data from 20 years ago, not exactly who you want designing something to go on your 10K fuel system.

Agreed on that regard. I would thread a FF5814 2 Micron Nanonet on it if I was running it due to horrid fuel quality. I just like the plug and play nature of the additional filter mounting make it easy to add and easy to return to stock.

Personally I'd find a 5um f/w separator to run on it, and leave the OEM filter as the final nano-net filtering.
 
I've read the OEM (68358393AA) is a 4-5 micron filter.
Docs has documentation that theirs is a 3 micron filter.
FASS claims to filter 2 microns absolute. And it "removes air" from the fuel.
Now I don't know much about this, still doing my research, but it sounds like FASS is the way to go if you want the best fuel for your trucks.
I know there big in the racing scene with high flowing pumps and all. But wouldn't the drop in unit be a good investment for daily & hauling?

OEM is 2 micron fass is 5 at best from proven tests besides the removing air claim is laughable as the filters are what prevents air from getting to the CP3
 
Docs is sh*t.

Just use stock filters, you're not going to get anything better value.

In your research, did you read this whole thread? Guys are spot on.

In short, no you don’t gain anything with a FASS on these trucks unless you need the volume for high horsepower applications and even then you sacrifice fuel filtration for volume.

FASS does not have a 2um filter since 2um hasn’t been a current standard since 2004, it’s old marketing. Just like the cat “2um” 1R-750 is still advertised as the best but it hasn’t been for 20 years, old specs and old media but people don’t care about real data they care about fancy advertising. Many of the filter FASS lists on their cross reference sheet have worse than OEM filtration specs. When I first started researching FASS and AD none of their filters were as good as OEM at filtration or WIF separation, so at least they have gotten better.

The OEM secondary filter is reported at 5um and the primary at 3um, both are excellent WIF separators. You won’t beat that with an aftermarket setup.

I also wouldn’t trust a docs filter in my truck, stick with OEM.

Yeah I see what your saying about docs. Didn't take long to find the bad press, I'll stick with OEM.
As for the FASS, I'll be passing on it as well. The DFFK seems to be the better option & at a 3rd the cost :)

lol, just stick with OEM filters. The media in the OEM primary filter is nano-net but separates water, has a heater, and a WIF sensor.
 
like said above, stick oem. however avoid buying them at the dealer. look online. my dealer wants like 250 for a set. you can get them elsewhere for alot less. i think i get fuel and oil filters for 90 total
