FASS filtration deception.
#106
If you put a different filter on the titanium, such as the Baldwin BF1275 you actually get 2 good f/w sep's vs 1 good one. But that's up to you if you want to spend the extra $70.
Thanks

Thanks for the input! Now if i go with the Titanium and go with the Baldwin like you said will that starve my injection pump or any other aspec? Think thats what i will do...
OK Kewl, Thanks guys for the help!! Much appreciated! Im going that way with the Titanium changing the screened one over to the Baldwin!

Yes you will. You will get 99% free water and 96.5% emulsifed water sep on the BF1275 and 95% emulsifed from the Donaldson, and 4um absolute from the Donaldson.
Those filters are good for about 120 GPH on the Baldwin and IIRC 100 on the Donaldson.

Would the emulisified water removal be a cumulative effect since both of them strip the water out? So I will have about 3.5 emulsified from the first filter and the Donalson will filter it even more?
Am I thinking this correctly?

I have updated my filters now, got the Baldwin BF1275 on this past week and also have the Donaldson. Fuel pressure sitting the same as before 10psi.
One more question does the Baldwin filter any or is it just a water seperator?

Just observing this one....but i will point out this one fact about the FASS:
It HATES restriction on the suction side of the pump. AND guess where the Water Separator is? Yup......and that is why it was 140 um. To allow the flow of 95+ GPH Fuel though it without cavatating the pump and causing pressure drops under load like some of y'all are seeing with the FS-1000 or equivalent. My 2 cents.......
Carry on.....

And yes.... I have noticed a volume problem on hard acceleration that I did not have before I installed the Baldwin.

Well here goes.
Since I noticed fuel starvation more than ever, I felt something was wrong. I also noticed she didn't make as much smoke. Hard acceleration gave me the "pop" of fuel starvation. Rarely had that before under the current Smarty and TST settings. The only things that changed in the last 10,000 miles is it turned winter and cold and I switched from the stock FASS WS1001 to the BF1212.
I was thinking the winter fuel and the cold was contributing.
Yesterday I removed the BF1212 and installed a brand new WS1001.
Took it for a hard ride and low and behold, smoke and power is back to where it was before the BF1212. No more "pop" under hard acceleration.
I suppose there is not much we can do if your truck has the mods similar to mine, with the FASS pseudo water separator, since we cannot have a filter with more restriction at that location.
I have a fuel pressure gauge and I was not seeing a drop in pressure. Always around 17 psi. So no pressure drop at the FASS port but a definite performance drop. Not sure why.
Thank you Diesel-Dan.... Looks like you know what you are talking about.
To this day I still find it fascinating that the first generation Duramax trucks that used the same common rail hp pump is able to produce 400-500 hp while sucking fuel through a 3 micron Racor (my old truck) and there was NO LIFT PUMP AT ALL. The GM trucks used large dia. fuel lines from the tank to the HP pump. The only lift pump used is the internal gear rotor pump in the HP pump. We have the same internal lift pump in our Cummins. I guess the Dodge fuel feed system all out blows ..... way too restrictive. Must be from the tank though since we replace the whole fuel line from the FASS to the HP pump with the FASS supplied fuel line.
I could see a future where I run just a pump and an inline filter. For what the FASS is advertised as, I just don't see the justification. It's pump is more just to get fuel through itself than to be an enhancement to the engine.

Hoot,
If it were my truck I would try a couple of things first. Try a FS1000, its a much larger filter so it should have less restriction at a given flow. Also, put the psi sender at the CP3 and see what its doing up there.
Another option you could try is a Racor B32038P, if it fits. Its 4.4" in diameter, but its a 30um 150 GPH filter, should flow plenty. If the FASS doesn't pull thru that I wonder if its the FASS??
Next I would consider a larger diameter fuel hose between the tank and FASS to aid in drawing fuel.
If none of that worked I would probably turn down the power and run a f/w sep, cheaper than a new motor from no water separation.

Some day when I have the time I might redo the line from the tank to the pump though. Is there a kit for this?
