Excellent response Ashley. That is a really big help.

Our concern about the FS1023 is justified. My concern is a water episode from a bad load. I would want the first filter to be able to handle a tablespoon or more of water at 90+ percent. Since you were expecting the final filter to do the major water separation, I would want a drain at minimum, a clear bowl would be best (Racor)

Ultimately, I would think a well spec'd water separator/pre-filter should be the first filter. 10 or 30 micron with a drain at minimum. Get the water and the big stuff first. Next you take it down to 2-5 micron with the final filter.

All at 90-150 GPH and 16+ psi depending on model of pump.

 

Thank you for the responce.. A few observations/questions..

Fleetguard rates the FS19768 at 140um at 100%, and the FS1023 at 100um at 100%. Per Fleetguard the media is different, the FS19768 uses water striping media, the FS1023 does not. The FS1023 is only a wire mesh screen. The FS19768 is a water stripper; the FS1023 is not, it was never designed to remove water just to keep chunks out of the pumps. The drain is only there to remove sediment, if you get water separated from gravity then great, but thats not the intent.

Only the FS19768 has a 50% removal rating per pass, 0 x anything is still 0 for the FS1023.

I am curious where you get the info stating that the FF5712 or HF6604 are water stripping filters? Per Fleetguard they are not, their media is for particulate removal, not water.



I don't have data on the Donaldson, but the FS19594 is only rated at 20 GPH.

I suggest you look into the Luberfiner LFF9594, the emulsified water sep is a little lower, but its rated for 90GPH. The FS19594 will fall well below the 90% rating when 20 GPH is exceeded.



One last question. What was the reasoning for using the hydraulic filters? They are rated on a multi-pass bases, and fuel filters are rated single pass. Most, but not all, filters that are rated multi-pass are not as efficient single pass, some decrease 2-4um. Since the HF6604 is 3um absolute multi-pass, and is not tested single pass, there is no way to know its efficiency on one pass (which is very possible for fuel/contaminates to only go thru the filter once before the injectors.)

Again, thank you for your time.

 

It sounds to me like FASS finally decided to start paying attention to the filters. People finally realized that was really the bigger issue all along. Chickens are coming home to roost now that the fuel-system-in-a-box hype has worn off.

 

Brad and Ashley @ FASS:

My thanks to both of you for your reply to our DTR Members on this water filtration issue!

As I have stated before. Just put an FS1000 on the suction side of the pump. The only issue is the filter can only support 95GPH. So on the smaller pumps it will work just fine. The bigger ones may be an issue. Also, this filter has a 10 micron rating. Perfect for a pre-filter before the 2-3 micron finishing filter. I have also left my factory filter in the system. This is my "Last Chance" filter. This type of setup is just like a marine fuel system would be. But hey, at least FASS is working on it. It will be interesting to see what they do.

 

Great information!

My fuel filter unit is a Raycor 4120 unit bolted to the suction side of my FASS unit. It has 3/4" ports running 1/2" fuel lines complete from tank to the VP44. It has a priming pump and priming fuel vent which helps when changing fuel filters. My fuel filter is a Raycor R120 unit (10 micron), both together handles 120GPH! There is a yellow tinted clear bowl on the bottom which holds up very well which is where I drain any water from the filter.

My Raycor fuel filter unit is my pre-filter (10 micron) and my stock fuel filter is running a 3 micron unit.

I've had a couple of people on this board tell me that my setup would NOT work well but with all due respect to their opinions, my setup has been working PERFECT for me for approx. 3 yrs. now and I'm still rolling hard!

 

I run Racors on the 1st Gen w/the exception of smaller lines and NO FASS. I have another Racor head I plan on installing to replace the standard 1-14 head with a Cat 2um in front on '07. R45S (marine 2um) secondary and anything BIG (Racor only, of course) as the primary.

That commonrail presently pushes through three (yes "3") filters including the stocker with the stock in-tank pump and maintains 5psi at WOT with the Smarty jr. on SW2, default. FASS? No thanks.

Nothing but clean, dry fuel ever getting through my fuel lines.

 

When the pump on my FASS takes a crap it'll get replaced with a quality pump and two Racors. The 10 micron 120 is a perfect water separator pre filter for this application vrj. That's the one I was considering putting on my FASS 150 but it's too long for where the FASS is mounted.

The FASS is one big honkin stack of space hoggin contraption. I have yet to find anyone that found any hp or mileage with the FASS so I don't understand the benefit. By separating the filters and pump it will be a lot easier to locate them and I'll end up with better filtration than OEM.... at that point I will only have myself to argue with LOL

 

Hoot,

I am currently running the Raycor R120T (10 micron) filter but I also have the shorter Raycor R90 & R60 filters that work with the Raycor clear (yellow tinted) fuel bowl w/drain port. These will fit the Raycor 4120 unit. In fact, the Raycor filters (R45, R60, R90 & R120) will fit the full 400 Series line. The difference is the flow characteristics (45GPH - 120GPH) and pressure (15psi's - 30psi's).

Since the Raycor brand is usually more expensive that Baldwin & Fleetguard brands, it is somewhat harder to find at your local truck stop so I cross referenced to find that the Baldwin BF-1283 will work great on the Raycor unit (center threads 1"-14).

This took me forever to find since there were other Baldwin and Fleetguard models that would fit but my local truck supply stores and truck stops didn't carry all of the ones that were a cross reference. There weren't many.

The Baldwin BF-1283 is an all steel unit with a drain port on the bottom and is approx. half the size in length as the Raycor R120 filter and is less expensive than the Raycor units. I carry two (2) spares at all times as backups or incase I am on the road and get a bad batch of fuel.

FASS makes great products also but I started using my Raycor prior to purchasing my FASS fuel pump. I have the FASS fuel pump only, without the air seperator and filter. I like the fuel pump. It works great for me even though it was a little expensive but I like the warranty and product quality. I went through a few Holly Blue's and Blacks in a couple of years and got tired of wondering when the would quite on me.

Hope this helps.

 

This place has alot of Racor stuff with good prices:

Ebay links not allowed

The last elements I bought from them cost a little less than half they are selling for many other places I looked.

 

vrj,

Just make sure your cross referenced filter has good specs. Look for 10 micron in a pre-filter with high water removal capability....over 90%.

You can get the Racor 120's for around $30 each online.

I have had good service from my FASS pump. No complaints there. If I would have known what I know now though I would have used my own filter heads and just used the pump like you. It would have been a heck of a lot easier to install that's for sure.

 

I just replaced my WS-1001 today with the BF-1212. This means I went from a 144 micron trash filter to a 10 micron real water separator.

 

The BF1212 is 20um.

 

Got a WIX 33405 to put in place of the WS 1001 that was useless. Anybody tell me if the WIX 33405 is as decent as the BF 1212? I found a whole bunch in the back of my barn and what do you know, it fit perfectly and the box says fuel/water seperator. Got to be better than the 1001 right?

 

Better than the 1001 yes, but Wix won't publish or tell you their f/w separation rates. I prefer to use what I know is good.
