"so the point here is almost all metel can type fuel filter will let dirty grease pass by..."
I think that is assuming a lot.
It might be more accurrate to say that any filter will fail if it it used beyond its design ratings. That is not uncommon when any device is used for purposes other than what it was originally designed for.

Good work Brian!
Words DO have different meanings and so looking them up is a good way to be less confused about that.
Which of the definitions for "bypass" do you think apply to the conversation on this conversation on filters?
After reading the threads on alternative filters for the greasecar kit instead of the Fleetguard I decided to use the Autozone FF760. It seems to me to "work" much better. by work better I mean I get noticeably more miles out of it than I do out of the Fleetguard. What I'm wondering is why is that? Does it function better? Just more volume? Or is it just because it's letting more crud though? If this is the case than am I just damaging my injectors more by using the Autozone? The Autozone filter is about half the price of the Fleetguard so I'd like to keep using it. But if anyone can confirm that I'm just doing more damage to my injectors than the 7$ savings isn't really worth it in the long run.
Any thoughts on this are appreciated.
I would stick with greasecars filter. they have spent a lot of time and money researching things.
as far as Dana..... Bite me
Would making it "multiple guess" help?
In the case of a filter a "bypass" is:
A: A pipe or channel used to conduct gas or liquid around another pipe or a fixture.
B: A means of circumvention.
C:A means of redirecting the flow of a substance around an appliance through which it would otherwise pass
Try this one on for size:
When the spring inside the filter experiences greater pressure than it is designed for, it will allow un-filtered fuel to monkey
(or, insert any word of your choosing here___________________________) itself into the fuel rail, injectors, and motor.
How, why, or what this is called is irrelevant to the stated fact of what did actually happen!
How this spring reacts is totally dependent on any of the following (or a combination of any/all.) They are in no particular order, and I’m sure I’m missing a few items.
1. Filtering capacities of said filter.
2. Quality of fuel.
3. Pressure build up (either sucking through or pushing past the filter.)
4. Design of the filter itself.
5. Temperature of the fuel in the filter.
6. Type of fuel in the filter.
I think this horse has not only been officially beaten to death, but it now resides in many different dog food cans (without a spring)
on the grocer’s shelves, waiting to be consumed and $hat out in the near future by some grateful canine named “By-Pass”.
The future of America is easy to perceive; Just visit Mexico or South Africa!
I have been using the FF760 for about 3 yrs. now in an 85 M.B. 300SD and was getting on avg. 2,000 miles on fuged oil. The longer the trip I would take sometimes 1400 miles round trip the sooner the filter seemed to clog up. My WVO flow was from the outside in and i have reversed that to flow inside out and also have put the T after the filter instead of before which to me means I will be getting a better flush of the filter with diesel at shutdown and will have diesel instead of wvo in filter when parked. I am hoping the changes I have made will give me more miles inbetween filter changes because some of the filters that were clogged previously I have cut apart and they did not look that dirty inside to me. I think it does make a differance wheather the filter you use is designed for the fluid to be filtered is pushed or pulled thru the filter on my M.B. it is being pulled.I have put about 300 miles since I made these changes to my FF760 and will post if it makes a differance.
