Fuel Filter Melted/damaged

[LStanphill]

Has anyone had damage/discoloration to the plastic on the engine mounted fuel filter? Assuming this is from the heating element? Was also impressed that it’s multiple layers of filter media, at least the Mopar/Fleetguard product. 15k miles on this filter.

Have not had any recall work done yet, intend to schedule soon.

Haven't done mine yet, but will take note.

I’ve changed my filter once and didn’t notice anything but I wasn’t watching for it either. I’ll look when I change it again.

First pic shows what might be discoloration from water contamination action at the bottom of the filter, where the water separates to.
Second pic looks fine...don;t see what you are talking about.
Thirds pic-- I am confused...is that how the filter came out of the canister or is that what it looks like after you cut it apart to inspect it closer.

In short, discoloration is likely normal use...but I do NOT see/understand the "damage" that you are referring to.

The plastic is melted/pitted/burned, not discolored from water, and the 3rd pic was just an FYI/Cross section after i cut it open

Using additives?

Using additives?

Only additive has been Power Service grey bottle.

 

[TCDiesel]

I don't recommended additives (only for Gelling if Clear#2) or use them.

 

[TCDiesel]

I should state MN has Mandatory Bio-Diesel, and Flints Hills does NOT endorse any additive with its Blends.. check with local refinery before using additive.

Also decades of Fuel repairs and I've Never could confirm they work for lube or water properties.

 

[LStanphill]

I wasn’t looking for additive recommendations, even though power services is endorsed by Cummins, and likely is not causing thermal damage to the recommended Mopar filter.

I was thinking more along the lines of an overzealous heating element. I’ll see what the dealer has to say when they do the list of recalls on the truck.

 

[TCDiesel]

Here's Why, All your doing is adding the same additive supplied by the Refiner, Flint Hills test their fuels 35,000 Times a month, its dead on from the refiner.

Take your additive and test it to see what your really buying? Yes, years back the stuff was great and worked...

OK...I can see that now. NO idea why!!!

Is there a heating element in the filter on 4th gens??

What about the "damage" in the 3rd pic??

 

[TCDiesel]

Their is.. and if Memory serve Me it shuts down at 65F....Now I've hot wire the 3gen Canisters on My bypass setups so that required Me to test how hot it could get, the element could never get above 110F. Pictured 2003-07 5.9 Canister.

I certainly could be wrong but that doesn't look like heat damage to me. It looks like a chemical attack on the adhesive that the bottom of the filter is bonded to the filter media with.......... ????? Just thinking out loud.

I agree.

I just did my fuel filter last week. The area you are concerned about is the top of the filter and the fuel heater is at the bottom of the filter housing as far as I can tell. I remember this so well because I wanted to shoot the SOB who came up with the plastic top of the engine mounted fuel filter...

 

[TCDiesel]

Heater element is on the top (WIF) Water in fuel sensor on Bottom.

 

[CoastyAV8R]

Ahhh, there goes that theory... Thanks TC
