who has a 2 micron fuel filter?

[OT-OF-HERE!!]

Series filtration

with all the opinions flying about has no one on here monitored pressures pre and post the 2 micron filter?



seems incredible that anyone would bolt on an additional filter not designed for this application and not monitor pressures firsthand ...



c'mon guys someone prove me wrong and give me some pressures

Rbatelle makes a good point about the Series Filtration. I'm using the multiple/series filtration only I'm using (2) 2 micron filters and as opposed to (1) 2 micron filter there was zero difference in fuel pressure as indicated by my Autometer gauge. Therefore, I think (2) 2 micron is the way to go. If it doesn't diminish your pressure then then why not capture even MORE of the crud. In my case and the driver to my decision to use (2) 2 micron filters I have edm'd feed tubes which remove the factory screen in the feed tubes and allows for considerably more flow and since I didn't have the additional benefit of the screen any longer I knew it would be essential to have maximum filtration without losing pressure/volume to the sticks.

A true absolute 98% 3/4 mic That means it gets 50% of 3/4 mic on the fast pass it took our 16 GPM Pump to 4 GPM, Racor. fleeguard 2mic and others were at 12/13 GPM. . I call their ratings system (BS). . we took the 3/4 mic filter install it in a popular system , it drop the volume to 1/2 GPM @10 PSI. .



The filter ratings these companies are using is tantamount to the lumber industry. . anyone seen a True 2x4 lately

Call Summit and get the Permacool unit and it comes with the 2 micron and it's about $35 and change. Can't beat it.

That's what I'm using, mounted after the factory filter. I saw no pressure drop when I installed it, but I'm using a Walbro pump, set at 18 PSI, and I've never seen a pressure drop, even at WOT.

2broke2smoke , you beat me to it , I have been looking for this since the 1st post , in a world like we have now , it seems that the consumer has to verify everything before use .

Read the wording really well... they state "... smallest particle filtered: 2 micron... "



I read that as it will catch particles as small as 2 micron, which indicates to me that is a nominal measurement (ie 50% efficiency)...



Even a window screen will catch a 2 micron particle once in a while...

thanks ... that's what i was afraid of



wifes '06 is a daily driven money maker ... 58 cents a mile ...



would spend a few hundred on a 2 micron filter in a heartbeat if i knew it was reliable ... .



as it is i have 1 freind with an '06 and 120k miles with no fuel related problems and another with 275k (hotshot) and no fuel related problems there either ...



thanks to all who've took the time to answer my post

2 micron filter

I don't measure pressure going into the 7 and 2 micron filter series. But coming out mine hasn't changed in the 8K miles I've had it on. With all the hype about more detergent in USLD I figured I'd see a filter slowly plug and pressures drop. I suspect either the junk is now out of the tanks, the hype was just hype, or the filters aren't doing much. Whatever, having the 2 micron makes me fell better I'm thinking the 2 micron Fleetgard catchs more than the 10 or 7 micron Fleetgard filter.

With stock lift pump my pressure just ahead of the CP3 tends to be consistent between 7 and 9 psi, towing or not. Accelerating with 22K combined gross I can occasionally make it touch 5 psi for a few seconds.

Yes, know that,...

I get my 2 mic ABSOLUTE, which is my 1st filter from Richard at GDP,. . and then the second 2 mic filter which is NOT absolute is after it exits the Mitusa prior to the rail. There is zero difference by adding that second filter in my fuel line lift pump pressure. The example TWest used was using approximately a 95gph lift pump pressure while the Mitusa is 275gph, fyi. I think more and more guys are getting to understand the benefits of volume,. . especially when you have good sized sticks and are running dual cp3s.

With the cost of some of these systems , I thought that using the Spinner II filter system [ centrifugal ] should work better with very little pressure loss , any ideas on that ?

I thought the spinner II was for oil??? Aren't we talking fuel???



I believe the BEST fuel filter is the Frantz that Gary is using... very fine filtration, very little pressure drop... the only thing you could do better would be a Gulf Coast Filter (yes, they make these for "recycling" fuel... do a Google search) mainly because of size...

[JFaughn]

steved , ya I know they were for oil , but it would seem that they should work for fuel & solve some of the issues stated here , sub micron , no filter , & very little pressure drop if any , but may only work with the 12v , because they use the pressure to drive .
So I thought I'd put the idea out there .

You cannot just imply all filters rated at 98% 3/4 mic will be the same as that one. What testing protocol was used for those numbers?



The filter spec tests were designed to give meaningful data for certain applications. That is why there are so many different test protocols. If you take test results meant for one range of applications (like hydraulic filters) and use those results to apply the filters to a different application (like one pass fuel filters), then do so at your own peril and do not claim intentional deception on the filter manufacturer’s part.



There is more to properly selecting and sizing a filter for a specific application than meets the eye.

It certainly was not J1985,I'm not fool by such easy deception... Please enlighten Us on what most test Pressures are 2 or 3 PSI?. . what's going to happen when customers filtration are ran at 10 Psi Plus?

As far as added filtration I am all for it,Just don't be fooled by Most manufactures Ratings...

Its about understanding the ratings, not that they are trying to fool anyone. Iirc we’ve been down this road before, though I’ll try to clear it up again. The test pressures are the pressure drop across the filter, not the supply pressure. Putting a larger lift pump on will raise the pressure because it will flow more. More flow = more pressure. Less flow = less pressure. It is all about flow rate!



Do not get hung up on pressure. Pressure is not a way to rate a filter. Pressure is a measure of the resistance to flow. Filters are rated at a specific flow rate. If you’re seeing excessive pressure drop across a clean filter then you have too high a flow rate or the fluid is thicker than the test fluid that was used to rate the filter.



Anyhow it is worth repeating: FILTERS ARE RATED AT A SPECIFIC FLOW RATE! Try to flow more fluid through them and typically filtering efficiency will drop and the pressure drop across the filter will increase. Using your Zinga example, if you need 16 gpm, then buy a filter rated for 16 gpm, not one rated for 8 gpm. If your pumping system can only handle a 2 psi pressure drop across the filter, then buy a 16 gpm filter with less than a 2 psi pressure drop, not a 8 gpm filter with a 5 psi pressure drop.

 

[TCDiesel]

WOW, this is a perfect Example!!!... I am not cheerleading... Zinga was ONLY one of the filters I tested. . I have had several REAL World tests for close to Three Years... Another Example in the lab testing. . Shingle manufacturers. 50/40/30 rated Materials. . Here in Mn 30 year Timberlines (GAF) Landmarks (Certainteed) Oakridge Ownenscorning... I Personally have to deal with the Salesman cheerleader ( Who was selling Furniture last Week) that now is a Door knocker Roofer who tells Home Owners that Roofs should last 30 years ( Buy X Brand) because their Yearly rating is higher... When in fact their Product is inferior. Most testing is done under the best conditions under controlled enviorments. . Not real world applications. .

I putting it back , because I did not see any reply ,
I thought of using the Sinner II , I know it is intended to oil , it may only work for the 12v s or after market fuel systems , because the pressure drives it , so I'm looking for any thoughts on it , hopefully constructive criticism's , not just I think it will not work it will not work , but whys & why nots .

 

[brods]

Twest: I’m done. Everyone else:



Keep in mind that the filter ratings are different for different applications. SAE, ISO and other standards organizations design the tests and ratings to be the most informative for specific applications. It is not an attempt to trick or deceive. It can be confusing, so learn and understand what the ratings mean. A filter tested for one application WILL perform differently in a different application.



Look for filters rated with #2 diesel and a single pass test, like the SAE J1985. If you find a filter with numbers you like, make sure the filter can handle the flow rate you need. Also remember the filter is just one part of the entire fuel system, so make sure your pump can handle the extra resistance to flow from the filter plus all the extra plumbing needed to install it. We all want the same thing; better fuel filtration.

I skimmed over the Spinner site, but it would seem it has a large pressure drop (full oil pressure to zero) since in the oil bypass arrangement the jets will discharge to the crankcase. With a fuel system where down stream of the jets needs to be pressurized, it would either spin way to slow or require a high pressure supply pump, which would present other issues. If the idea is sound for fuel, then spinning the basket with a motor might be less problematic.
