Who Can guess the mileage of this fuel filter?

[PHeadings]

How many miles?

 

[RankRam]

yuk!!!!!



50k???????

 

[Heavyweight]

2,500 miles!!!

 

[PHeadings]

RankRam,


Higher!

My last filter looked worse than that, maybe it's just the pic. I was down to 3psi under fulll load. That one got ejected at 25K



My guess is 75K.



Is that your filter?

Was it causing probs?

If not yours, 2nd or 3rd Gen--Not that it matters. Just wondering if there's another dead VP44 out there.



Another cattle-hauler was tellin' me once that his F350 w/7. 3 ran so much better after the shop replaced the FF, for th FIRST TIME @273K!!!!!!!!!!!!!!!

 

[BTighe]

90k miles?

 

[amsoilman]

How many miles?

Well I just changed mine and it looks about the same, which had 27,000 on it.

RankRam was close. It had seen 50,755 miles.

 

[Bschneider]

You need to change it sooner.

RankRam was close. It had seen 50,755 miles.

To me that's more than 5X of changes

 

[KBennett]

You need to change it sooner.

Geez, ya think?

I changed my first one at 7K miles and it looked kinda like the one above. The second is coming out this weekend when I change the oil at 28K. It's been a year so why not.

Believe it or not

My first FF change was at 30,000 miles and mine looked nothing like that. Should i have changed earlier probably but after changing mine at the 7500 miles the next time there was no difference in FF appearance or look from the 30,000 mile one and the 7500, But i was also using fuel that had been filtered 2-3 times before entering the tank and had no water in it, Conditioner i think goes a long ways.

Right now the Cummins is closing in on 105,000 miles and so far no problems with engine, I think my attention to air filter changes helped in that so far, I have changed mine with at little as 2500 miles, if it looks dirty change it, it goes a long ways in preventive maintenance. Oo.

 

[CMckee]

Geez, where you buying your fuel from?? i'd probably take the filter to them for a little show n tell.

 

[Elite1]

I change mine every oil change, 7500 miles... the filters are pretty inexpensive and I want to get the most miles possible out of my injectors & fuel pump.

 

[Scrappy]

I agree with Elite1, every 7-8K filter gets changed

 

[hasselbach]

actually, a filter filters better when it get dirty but the flow is reduced (so I've read on many filter web sites). A new filter may flow more, but less efficient in removing the crud.



I'd put that one back in and get another 50k miles out of it.

it does, and if you want, you can perform a little experiment at home to prove it... now it won't be in micron scale, but in a much larger scale. . with a window screen and different grades of soil/sand/silt/clay/dirt/gravel... pour some on and shake it a bit and see what comes through it... then do it again without removing what is left on the screen... as the bigger debris plugg the larger holes, no more of that size can get through and only smaller stuff can get in... the screen will get plugged up to a point where only the finest materal will get through...



you could also throw some lawn clippings into the mix to simulate bio/algi that could be growing in a fuel tank [grows in the layer between standing water and fuel... ]



it's a little crude of an experiment, but it sorta shows what is happening

 

[rbattelle]

Amen to what Nick said. If you think you're doing a favor to your engine changing filters early, you're probably wrong.



Nick, I recommend 1 change to your experiment. You should also throw some water balloons at the screen to simulate water in the fuel. The water balloons can be of varying sizes; tiny ones to simulate demulsifying additives and large ones to simulate emulsifying additives. :-laf

Looks just like mine that I changed that had 11K miles on it.

 

[Grayhackle]

Looks like mine that I changed at 10,020 miles. Cannister was clean. I dripped some diesel fuel on the new filter and it turned black just as your picture. I expect the filter to be black but I don't want to see any particles in the cannister!!
