FASS fuel filters

[TMutziger]

I have a FASS 95 series on my truck and am looking for a replacement element for it. I have a spare 3 mic. for it but am looking for maybe a 7 or 10 to keep on hand in case I have trouble in really cold weather. The 3 mic is the only one I can seem to find for a 95 series. I live in South Dakota where it may be 20 degrees above zero and -30 the next. Last winter we had terrible gelling trouble after all our fuel suppliers made the switch to ULSD. Nothing seemed to work other than to run a lot of #1, which I hate to do. I didn't get my FASS installed until spring after the weather got warmer, so I don't know how it will handle pushing fuel through such a fine filter.

Try this: FASS - Fuel Air Separation System - fassride.com There should be numbers on your old filter. I thought the filters are the same between the 95 and the 150. Just call your local Cummins Distributor and get the ones you need. Shadrach

I was thinking about adding extra filtration to my fuel system using spin on cannister filters. I had the same concerns about fuel gelling since I winter camp and ski a lot in BC and AB, and thus adding a fuel heater.



I already have 120 VAC silicone pad heaters for the oil pan and the batteries (made by Kat's) when I plug in, but they also have 12 VDC powered ones. I was looking for ones that would wrap around the filter. Looks like E TIP Inc, already sells one.

Don't know the wattage, so you might contact them. For reference Racor was using a 200-300 watt 12 VDC heater to warm their fuel filter in 2-5 minutes before starting the engine. They had a relay controlled by a switch in the cab.

The filters are different for the 95 and 150. I tried the FASS website already and all they carry for the 95 series are the 3 micron. I swear I have seen a Fleetguard 10 mic adverdtised to fit the 95 on some website, but I can't find it anywhere.

 

[RBridenbaugh]

Do you know the 3 micron threaded opening and thread pitch? Probably 1"-12tpi for the primary and 1" -14 tpi for the secondary filter.



You can figure this out by looking up the filter you have on the manufacturers website and it will give the filter seal diameter and the connector details in the specifications.



Then look up the filter you want to substitute and determine if it has the same tread connections.

You guys are worrying me a little here. This is my first winter with my FASS 95/95 and no fuel heater (OEM filter bypassed). I run Stanadyne and have on numerous occassions run my mouth about running #2 at below zero temperatures but that was with the OEM heater in operation. It is now below zero here. Things to make you go "Hmmmmmm".

Well you could just dose it up with anti gel and it should be fine. I think the fass has ports that you can plumb for engine coolant to circulate through but that would be a few more lines to run.

 

[TMutziger]

The place I bought the FASS system from claims that the pump has so much torque that it will pump thick fuel through the filter and gelling isn't a problem. They claim one of their shop guys started and ran his truck at -17 F. on straight #2 and no additives and had no problems. I would have to see this to believe it. Wondering if anyone out there is plumbing in heated engine coolant, or is it unecessary?

Unless you live in Antarctica... the proper dose of Stanadyne Performance formula will keep the fuel flowing fine in very cold temperatures. I've done diesel samples of untreated #2 and PF treated #2 at -13F and there is no doubt as to what it does for you.



Their web info says:



•Cold Weather Protection - reduces diesel pour point up to 40°F (22°C), and cold filter plug point by up to 25°F (13°C), depending on base fuel.



And thats the way its worked for me. The coldest I tested it at was the -13F I mentioned. It stayed there for a week. I had absolutely no issues. The fuel looked and flowed very well. The untreated fuel looked like slush.

Is it a 95/95 or 95/150?

 

[TMutziger]

It is a 95/95

 

[AH64ID]

I would hook up the coolant to the fuel heater before reducing filtration. (On a side not I gelled up last week and it was my 20um filter, not my 5 or 2um filters. . based on location, 20um is under the truck, 5/2 are underhood).

What is the model number for that 3um FASS filter? The only filter I have ever seen listed for the FASS 95/95 is a FF5712, which is a 10um filter. And the f/w sep is a FS19768. Honestly the FASS 95/95 has worse filtration than a stock filter.

 

[TMutziger]

The factory filter is a 7 micron at best. The filters that FASS sells with its unit is a 3 micron. How is the factory one possibly better? The filters for the 95 say FASS right on them and FF2003. I don't know if they make their own or source them out and just put their name on them. The 150 series uses Fleetguard filters and can be crossed with a couple other brands as well, along with a few different micron ratings, but I have only found the FASS 3 micron for the 95.

This is the part that kills me about FASS and AD, they don't seem to do any research on their filters, nor advertise the filter correctly.

Per FASS the FF2003 is a Fleetguard FF5712. Its it rated at 10um absolute and 5um at 83%. The f/w sep is a Fleetguard FS19768 it is rated at 144um and 50% free water sep, and 0% emulsified water sep (at only 20GPH). 3um was pulled from someones rear!!

The stock filter is a FS19856 it is rated at 7um absolute, 5um at 96% and 98% free water and 95% emulsifed water sep, at 60GPH.

As you can see the stock filter is FAR superior in filtration and f/w sep than the FASS 95 series. Throw a Baldwin PF7977 in the OE canister and it gets even better (5um absolute, 2um nominal).

So I guess we can start to agree on this subject,I can see you are the type of guy (Like Me) that checks into statements and Marketing,Fass and airdog have great Pumps it's their filters that I question!!!!!In fact some of the biggest Name filters I have found to be absolute deception in their marketing.

I agree completely. . Great pumps, generally poor filters. What FASS and AD need to do is use a common thread size, say 1-14, for both filters so that the end user has lots of options, as well as decent filtering.

Totally agree... in the meantime, do you suppose it owuld be possible to make an adapter that would work, or is filter circumfrence also an issue??

The gaskets appear to be of different size.



The first step is getting AD and FASS to really recognize the problem vs ignoring it.

 

[TMutziger]

Wow. I guess I was fooled by false advertising. I thought FASS was a reputable company and I took the advertising for truth. If you are right on those numbers, what filters can I use. The FASS is already installed and it bypasses the factory filter completely. I'm not switching it back. I want at least 3 micron filtration and excellent water seperation. Thought I was getting this with what I paid a lot of money for. Now what can I do?

Looking at the Fleetguard book there are no other viable options for filtration. The f/w sep can be replaced with a FS19694 that gets the free and emulsified water sep to 90%, but thats still only at 20GPH.



The FASS 150 HF6604 is the only true 3um filter I know of on the market. The only true 2um filters I know of that are readily avaiable are the Cat 1R-07xx series and the Donaldson crosses, neither of which will attach to your FASS 95.



The FASS 95 uses 13/16-16 thread for the final filter, and 3/4-16 for the f/w sep, both of which are not common, so best of luck to you finding a cross, but I haven't and I have done some research on them.



Honestly your best bet is to put the OE canister back in with a baldwin PF7977, but if you dont want to do that you would need to either change the FASS or add 2 more filters, pre and post FASS, to get that 3um filtration.
