FASS filtration deception.

[JCyrbok]

what is a good FF for the FASS 150 (already switched out to a BF1212 for w/s). Currently I am using the Napa 10micron one (cant remember the number the top of my head). I would like to use atleast a 5micron or better filter, even though Bousch says 10micron is good for the VP44.



My only concern is that it gets COOOOLLLLLDDDD here in Michigan and I would worry about the filter locking up. I do run Stanadyn and have never had a problem with the 10micron icing/gelling up (down to -25 sustained for days), but I do not have any fuel heater, I ran straight to the VP.



I want better filtration but worry about being stuck in the winter. Ideas, suggestions etc? LOL



Thanks

HF6604 would work perfect.

I picked up my BF1212 last night and installed it. Seems it was harder to bleed with the Baldwin though. Pressures are the same on the gauge. I did notice I only had 10 psi at start up and then it jumped right to 45psi where it always sits. I might have had a little air pocket yet as I didn't drive it after..... I'll know when I leave work today if it's bleeding down after sitting.

I'm considering a Racor R120 Series 10 micron (R120T) with a clear bowl. They also have 30 micron (R120P). It has the correct thread but I'm not sure if the gasket/seats are the same. It's rated at 120 GPH. The max pressure is 15 psi. I'm pushing 16 so I think it's safe. There is usually a bit of breathing room on pressure specs. If not can go with the R90 series that has 30 psi max but only 90 GPH. Actually for me that should be plenty. Racor is known for their "Aquabloc II) water removal technology. The clear bowl is great. You can add a heater if you want.

Looks like this without the head. . The length gives it the high flow. The R90 is much shorter.

Since the f/w sep is on the vacuum side of the pump it won't see the pressure.



I have thought about going to a racor as my first filter, but the bowl scares me on gravel roads.

Thanks AH!,

I don't have the gravel issue where I mostly drive. It can be shielded if needed.

Okay after a couple days I have found something with the BF1212 I didn't have with the FASS "water separator". My truck is a 12V and my FASS runs at 45psi. With the FASS filters once it was bled it as soon as I would turn on the pump it would shoot right up to 45psi. Now with the Balwin W/S it comes up to 10 psi and sits there until I start the truck and then it takes about 30 seconds and it goes up to 45psi. Every time I shut the truck off this happens..... even if it's just for a few minutes if I run into the store or something. I installed the little o-ring seal in the mounting stud..... I'm not really happy with this and never had this issue with the other so called water separator. Did I install something wrong? Is this a flow issue? Is it normal with this Baldwin W/S? Will it hurt anything?

 

[AH64ID]

That's an interesting one. I have no idea why it would do that, the pressure differential on the filter when clean is very low.

It almost seems as if the FASS is bypassing too much back to the tank?

I would call FASS and ask them, the filter they are specing to replace the FS1023 is 10um, vs the Baldwin 20um. . so the Baldwin should have less restriction.

 

[PRohr]

The pump worked fine before... . it's the Baldwin W/S. I'll throw another wrench in this..... I had another FASS W/S here as I bought two along with the filters. I put the FASS one one and pressure doesn't drop when the pump is shut down... . just like it was before.

 

[AH64ID]

That is really weird, I highly doubt the filter has a check-valve in it.

I would call FASS.

 

[PRohr]

I was sent to VM..... I left on for a tech..... we'll see what happens when they call back.

I just got off the phone with Chris from FASS. He said my fuel pressure issue is with the Baldwin BF1212. He said they are aware of the issue withthe old FS1023 W/S and have changed the filters now. They are going with Donaldson. The P/N he gave me are as follows:

150 or H/D series:

Fuel Filter - Fleetguard or DPP filter is fine and meets specs.

W/S - Donaldson P551001

Specs on the P551001:

10 micron - 98% Eff, 95% free water, 95% Emulsified water

95 or Titanium Series

Fuel Filter - P553203
W/S - P550550

I didn't get the specs on those as I don't have that series. I would suggest you contact FASS and talk with them about the recommended filter and W/S now. The Baldwin is going in the garbage so I just threw out $15... ... I told him they need to have their rep log into the TDR and post up the info.

[JCyrbok]

no problem with the Bf1212, my presure at key on come up the same as it did with the other w/s. There is also no difference in idle psi and wot psi



Not sure why there is such a difference for you.



Also isnt 45psi a tad bit much? Or is it different due to the generation of trucks? ( I have a second gen 24v with vp44).

I have a '98 12V... . that's why the higher pressure... . maybe my filter is junk... . IDK... . but I am going to pull the BF1212 off and put the Donaldson on tomorrow.

If the Donaldson/Fleetguard filters work, the Baldwin should it. . The Baldwin has less restriction.



I am not sure why you are having the issues, but it shouldn't be because of the filter. The Baldwin has the same water separation, but is 20um at 98% efficient. I have the Baldwin on mine, with my OE pump and have no issues.

 

[PRohr]

I don't know either... . like I said I switched back to the FS1023 for testing and the pressure was back to normal. FASS said the same thing as i am... . it's something with that Baldwin W/S... ... IDK. I have the Donaldson coming and I'll pick it up at the Cat dealer tomorrow and spin it on there and see. I am going to put the FS1023 back on tonight as I don't like that pressure drop. Maybe I'll cut open the baldwin and see if there in an issue internally.

Any body have any info on a F/WS for a FASS 95? Looks like everyone is using 150's.

FYI - my 1st diesel was a 85 Ford 6. 9. The first time I drained the W/S I found about a teaspoon in 1 qt. Never again did I find any water (180,000 Miles). I never found water in my 97 Dodge,(175,000 miles) ditto for my 04 (112,000 Miles). Either I am buying water free fuel all over the country on none of the stock W/S work.

Bill, Here is the updated W/S and Fuel filter that FASS told me to use on the 95 models:

95 or Titanium Series

Fuel Filter - P553203
W/S - P550550

 

[PRohr]

Well I did some "testing" tonight. I think I wore out the threads spinning on and off all these filters. The BF1212 will bleed down and cause a low pressure (10psi) until I start the truck and I assume it goes away because the P-pump pulls the fuel up to it and bleeds the FASS... . not good. I put the WS1001 on there and bled the FASS unit and I have 45psi right away. So I started comparing things.

BF1212 - WS1001

Do you see what I see:

#ad


#ad


Baldwin Internal Sealing ring:

#ad


WS1001 Internal Sealing ring:

#ad


I think that might be my bleed down issue... . Now I did some measuring to confirm and I'm not sure now but from the top of the outer sealing ring to the filter head where the inner sealing ring sits is:

Baldwin - . 145"
FASS - . 211

Both should crush and seal I would think. The ID of the Baldwin ring is a bit smaller than the FASS one and "rolls" onto the mounting threads where the FASS one is snug but slides up. Any ideas? Maybe it's because of the higher pressures of the P-pump I don't know but I can't have that low fuel pressure and bleed down. It's not good for the IP or the FASS.
