Fuel filter change

[Cummins12V98]

11 HO and current 15 zero issues RnR cap on either 140k combined.

I was at 30%, and just feel better about changing fuel filters every 10k - I have no basis for this though.

Makes you wonder what else the algorithm includes for fuel filter life. On my ‘18 it was exactly linked to 15K miles.

As far as servicing early I’d save the money. Cat published a paper years back on the negative effects of over servicing fuel filters. A used filter is a better filter than a new filter, to a point.

No issues going until it tells you to change it. Even 15K miles is a conservative number with the design of this filter system.

Engine mount always looks good at 15k. Really impressed with the RACOR primary filter.

.

Totally agree.
The same holds true for oil changes and/or oil filters.

 

[pwr2tow]

The biggest problem people have with removing the engine mounted fuel filter is over tightening.

Lubing threads on a part that requires specific torque numbers can lead to over tightening, even breakage. So I don't recommend lubing the threads.

Now someone's going to say, "well the threads are wet with fuel". True but fuel is not much of a lubricant AND one must use common sense.

Unfortunately, when my truck says it has 0% left ,and I'm only 13K into the filter, the dealership is going to have access to that data and if I have warranty issues I don't want that to happen. My truck will reach zero WELL before 15K.

What year is your truck?

I wonder what else they use for filter life besides miles.

 

[Cummins12V98]

When it says change ya better at least reset.

As well as the air filter. 30k may be justified for guys that live and work in dusty environments but out this way dusty it is not...
I'll have 4 OCI on this filter at the end of this cycle and it's really no worse for wear. Almost zero dust/dirt tapped out of the filter. No compressed air. I hate even disturbing it but I do check it every oil change.

I've got a filter minder I ordered some time back. I used the part number off one of our cranes with a QSB6.7. One of these days I'm going to get it installed.

^^^^^ ZACTLY!!!

BIG question, metric or standard socket.

Makes no difference as the instruction sheet for the under hood fuel filter states one can use either.....

Just clarifying, thats with a 6 point socket.

 

[SnoKing]

It is much easier using the aluminum filter head instead of the plastic one . Comes off and on much easier

Wouldn't an aluminum cap heat sink more under hood heat to the fuel?

Do you really think it makes a difference?

Don’t these MAF sensors measure restriction? I thought they would tell you to replace it if the filter was dirty.

Don't know if it's the MAF but you are correct, the truck will tell you when your air filter is restricted. But I change earlier.

 

[gsbrockman]

I’ve always changed before or near the 30,000 mile mark as suggested by the owner’s manual....but I have read the truck will indicate when it does need changing, in the instance of some abnormal conditions.

 

[Minnow101]

My front filter always looks that clean. I'd bet that front fuel filter can go another 10,000 miles before changing out. But I don't buy scratch off's or take trips to Indian casinos's either so what looks like a perfectly functional filter gets changed with the rear filter.

I just prefer a gauge to be able to monitor condition rather than get a surprise notification out of the blue. Both Donaldson and Fleetguard are very adamant over servicing is a thing, and that a dirtier filter filters better than a new. Fleetguard suggests Changing based on air restriction as measured by an air restriction gauge, not by miles or hours.

And yet Ram did away with the filter minder on the gen4

As far as I know the message you get on the dash is air flow resistance/restriction. Never have seen the message due to miles driven.

Have you read what the specs indicate on a MoPar filter or a Fleetguard filter? I think those things can contain nearly a pound of filth....

 

[JR]

Probably more than a pound. Some of their larger radial seal filters are capable of over 6000 grams. Every single piece of literature I've seen from Fleetguard says to change based on restriction not hours or miles, in the 6.7 case is around 25".

It is readily available on their website but I can post some of it up a little later.
