Fuel Filtration, ULSD, and Fuel Prices..

[JTodd]

Hey Guys,



I've been reading a number of posts recently concerning denied warranty coverage based on "dirty" fuel claims from DC on '06 models, primarily related to injector failures. I have a few questions:



1. What are the best options available for for upgrading my stock fuel filtration system?



2. Will the ULSD be any "cleaner" or is that relative to the tanks at each station?



3. Are we to expect any increases in fuel costs resulting from the ULSD swap?



Thx



JT

1. Best isn't necessarily the cheapest, but for the money the Glacier 2-micron kit is hard to beat. You can also run the 7-micron filters in the stock canister instead of 10-micron.

2. The fuel itself isn't dirty, but it has a detergent effect on the storage tanks and lines to the pumps, resulting in a bunch of old debris being dislodged into the fuel. This should diminish as time goes by and the systems clean themselves out, but for now I would be concerned with just the stock filtration. At a minimum make sure you have that 7-micron OEM filter in your canister.

3. I've heard around 10-cents per gallon more, but with the way fuel prices have fluctuated this past year I don't think it's going to be easy to determine.

2 mic. filter and warrenty

I have these concerns also. Not because of the new fuel but because these CR engines (all of them) need clean (<3 micron) fuel. So I am nearly finished installing a 2 micron Stanadyne FM1000 between the stock filter and the CP3. (I bought the unit before the Glacier system came out and the FM1000 has a few features I like better. ) I just have to get a fuel pump now. Anyway, I am concerned that this could be used against me in a warrenty claim. What to you guys think? Should I ask my local service manager before I complete the install, or just be prepared for a battle if I need a warrenty claim?

Anytime you modify a system on a vehicle you risk voiding the factory warranty. In your case of just adding a filter, you might be OK. But once you replace the factory lift pump with an aftermarket I'm guessing the fuel system warranty is gone. If you happen to later have a leaky CP3 pump, more than likely the dealer will deny coverage due to your "modifications".

Even so, I have no regrets about any of my fuel system mods. DC's fuel delivery design is a joke, and there is no way I'd trust the stock system on long trips. Better to prevent problems from happening in the first place than to do nothing, risk becoming stranded, and then be at a dealer's mercy.

That's the problem. The stock fuel delivery is a joke. So if you fix it, you risk the warrenty. In this case, it is a mod to fix a problem (as we see it) not to break the dyno. One would hope the dealer would be sympathic in this case. But, adding a filter, while providing better fuel, could be argued as a retriction and starving the system of fuel, pressure, etc (even though I run a mechanical gauge). The stock fuel pump probably won't hold up to 2 mic. filteration, therefore, a better fuel pump is needed (Walbro in my case). Then D/C says modified fuel system = no warrenty. That's the dilemma.

I'm going to let Dodge worrry about mine as long as it's in warranty. Best bet is to use the new 7 micron filter and change regularly for a while.

Can you guys use a RASP (DTT) on the 3G trucks? I have one on my 2G and I have a great piece of mind about my fuel pumping capabilities. Now I am not there on my filtration only 7 micron. I am following this very closly too as it is time for me to sell the 2G and get an 06 or 07.

Problem with this is that all the time driven with >5 micron filtration you are harming you engine. At least according to Cummins, who I think has published literature stating 5 micron filtration for CR engines. Dodge won't do it. They compromised with the 7 mic. element. Catapillar has done a good bit of research on this and found a substantial amount for wear in the CR components with 3+ micron sized particles. I believe they spec 2 microns filter on their stuff now. So, at 100001 miles if your injectors crap out, your are out of luck, whereas those injectors might last 300K or more with well filtered fuel. It would be kinda funny to see D/C try to claim bad fuel as a source of a bad injector with 2 micron (with 98% efficiency) filtration.

does anyone know the part # of the fleetguard 7 micron filter?

For some time now, I've been using the Frantz sub-micron fuel filter on my truck. Like others, we are now on the ULSD, and if ANYTHING will plug up in a hurry from garbage in the fuel, my Frantz will!

So far, so good - no observable difference in fuel supply PSI - of course, the pusher assist and relocating the stock LP back to the frame rail next to it all helps...

:-laf :-laf Right.



If you modify the truck, even if you've made it better than it was, you're on your own. There is no way any normal dealer will look at a stanadyne filter on a truck with a failed fuel system component and let you warrant it. If need be, they'll blame your install for contaminating the fuel system.



Just another reason I wish I could've opted out of the factory warranty and pocketed the money instead.



Nice job going to the FM1000... I've got an FM100. Where'd you mount the 1000? It's a pretty tall filter...

I still think that's the best option. Let DC pick up the tab if something breaks. Can't beleive there would be much internal damage to the engine using a 7 micron filter. If the IP or an injector goes bad they can cover it.

I finally gave in at 93K and went completely after-market on the fuel system. My warrenty's shot but it's close enough that I didn't care.

Oh. . they did give me a new VP44 at 70K miles so I'm ahead of the game.

It's mounted above the CP3 in front of the intake horn. I'll try to get some pictures up this week. It came with a 5 micron filter that is shorter. 4 inches I think. Stanadyne doesn't make 2 mic filters for this except for OEM applications. So I'm searching all around for the shorter 2 mic. filter. I have a parts list that says a John Deere filter will work, so that's what I'm looking for now.
