PF7977 really is a GREAT fuel filter.... Other filter data too...

[AH64ID]

Recently I have been looking at supplemental filters to add to my truck. I know I want an additional fuel water sep and a 2 mic. I have been madly researching the ratings of the commonly used filters. I figured while I was at it I would get the entire ratings for the PF7977 OE style fuel filter that many of us use...

Here is the scoop on it. 5 microns absolute, with an average efficiency of 99.31%. Water stripping: 97-99% free water, 92-95% emulsified water. And it has a dirt holding capacity of 25.5 grams. 509.1 sq in of filtration media...

The OEM filter is the FS19800E, 7 microns absolute, 96% at 5 microns, 95% emulsifed water removal, and 98% free water removal, w/ 14g of dirt holding capacity.

Here are the specs on some commonly used fuel/water seps and fuel filters..

BF1212 (fuel water sep) 20 microns absolute, average efficiency of 86.34%, Water stripping: 97-99% free water, 92-95% emulsified water. And it has a dirt holding capacity of 35.9 grams, 579.0 sq in of filtration media, and a flow rating of 210gph.

FS1212 (fuel water sep.. same app as BF1212) > 20 microns absolute, 20 microns at 95%. Water stripping: 90% free water, 90% emulsified water. And it has a dirt holding capacity of 22 grams, and a flow rating of 90gph.

BF7633, this is commonly referred to as a 2 mic filter, buts its not. 5 microns absolute. Average efficiency of 98.11% And it has a dirt holding capacity of 27.4 grams, 701.6 sq in of filtration media, and a flow rating of 170gph. But this is a multipass rating...

FS5320 this is commonly referred to as a 2 mic filter, buts its not. Its 5 mics absolute, and 90% at 2 microns. Single pass rated.

Cat 1R0750. 2 mics absolute, single pass rated.

Donaldson P5513132, 2 mics absolute, single pass rated.


The 1212 series is very commonly used, but I received emails from both Fleetguard and Baldwin stating that it is a vacuum only filter, were not using it in that fashion.. I have asked for an equivalent pressure filter part number.


And here is the real kicker... While researching which filters to put on my truck I looked at the air dog setup based on all the positive comments. Well I got the specs on the filters and I am very unimpressed.... My single PF7977 is a better water stripper and equivalent filter... From what I understand the Airdog 100 flows 100GPH, yet the flow of FF5613 is 59.97 GPH, and the FS19768 is only 19.82 GPH... seems to me the pump operates above the rated flow, which leads me to think that they are not filtering at max efficiency.... I also noticed the FS19768 is not rated to remove any emulsified water. Its rated at 50% for free water. Also the FF5613 is a 5 micron filter, not a 3 micron. FS19768 is a 140 micron filter.


At this point I am going to run the cat or Donaldson 2 mic between my OE filter and the CP3. I will keep the PF7977 in the OE mount. I will add the pressure equivalent, hopefully there is on, of the BF1212 between the OEM LP and the OE filter bowl. This should provide the best filtration possible.

Just talked to a Baldwin filter engineer today about something unrelated and he said that they are currently working on a filter project that filters "sub-micronic" particles. I'm not sure exactly what that means, but i interpreted it as being able to filter below 1 micron in size?!?!?!

Nice writeup ah64id... :thumbsup

That would be sweet...

Well I just picked up my 2 FB1311 filter bases and 5ea of the BF1212 and BF7633 to go with the 5 PF7977's in the garage... I hope to get the 1212 and 7633 installed win the next week or two.

ohh, I forgot to mention, I've ran the PF7977's 10k miles before i change them out and that was on my '04.5 and my current '06. I believe that you can go 15k miles on them, but it's just easier for me since I change out everything (oil, air, and fuel) every 10k miles.

My dad is already running the filters I plan to add and we were talking today about what interval we feel is adequate. Right now I change the 7977 every 10K, but I am thinking that will all that filtration 20K will be fine for all 3 filters.

You should change your custom title to "Lord of the filter"....great post:thumbsup

I just want to know what I am putting on my truck..

Now I am just waiting for my GDP parts to get here and the install will begin...

I hear ya man! I got a huge Donaldson water seperator that I am waiting to get into mine to join my Cat 2 micron.

I was bummed today when they told me that if cat was reporting 2 microns that it was the old standard, which means its a 5 micron like the rest ... So for the price I just went Baldwin as they are on sale this month at Kenworth and I got them for 9.xx... I had kinda wanted to run a yellow cat filter underhood for fun

According to Baldwin the SAE standard changed in the late 90's. Prior to the change 2 microns was "testable", and was commonly used. When SAE changed the standard there was no way to measure 2 microns, 5 microns became the smallest absolute rating. It was found that most 2 micron filters on the old standard were 5-7 on the new standard, so some filters are even better but rated higher.

So what I gathered was that Baldwin and Fleetguard now report on the new standard... which is a change and why many refer to the filters as 2 microns... And Cat and Donaldson still report on the old system.

So the Baldwin BF7633 meets all the requirements of the 1R0750, and I can get the 7633 for about $4 cheaper, so thats what I will run...

It kinda annoyed me that companies are reporting ratings based on 2 standards... but they all filter about the same...
