Attention: TDR Forum Junkies To the point: Click this link and check out the Front Page News story(ies) where we are tracking the introduction of the 2025 Ram HD trucks.
Thanks, TDR Staff
I'm hoping for only motor brushes.
Two year warranty except for motor brushes.
FASS system on for just over a month now. The bypass regulator does like to sing when engine is idleing and not using much fuel.
I've been asked what's that noise. My repy is thats my high performance fuel system telling me lets hit the road.
Really though it does make more noise than I expected. But now I'm used to it. I don't hear it driving just at stop lights.

Was told that the pumps flow rating is 130 -150 gph range.
On the filter it says max flow of 25 gpm with a 10 micron filtering.
Don't have to worry about filter restriction with high fueling.
With the edge ez on 6 I see about 11/2 to 2 lb drop on fuel pressure at wot from idle. Gauge is connected post filter at the injection pump.

10 Micron Filtration ???
The FASS system only filters down to 10 microns??
This TSB requires a 2 micron filter for ISBs.
http://dodgeram.info/tsb/1998/14-02-98.htm
"Whenever a fuel filter is replaced, make sure the replacement filter is p/n 04883963AB "
"NOTE: DO NOT USE OLDER STYLE FILTERS ON THE 24 VALVE ENGINE. THE OLDER STYLE FILTER DOES NOT FILTER TO A FINE ENOUGH LEVEL FOR THE INJECTION PUMP USED ON THE 24 VALVE ENGINE. "
This data section at Dave Fritz's indicates the fuel filter specified in the TSB is a 2 micron one, which replaced the previously specified 7 micron one.
http://www.dodgeram.org/tech/dsl/Facts/98ISBspecs.html
"* 04883963AB is a new 2 micron fuel filter element, which must be used with the Chrysler ISB application.
The 2 micron filter replaced the 7 micron 04883963AA filter, which is no longer manufactured. "
If the FASS system truely tops out at 10 microns, this is unacceptable for the VP-44. Maybe somebody can locate a 2 micron filter, like this 98% efficient @ 2 micron CAT filter, that will fit on the FASS head.

Good point B9Mile. I thought it was 10 micron for the ISB's which is why I run a 5 micron filter. Looks like I'll have to get some 2's now. However I swear I read it was 10 micron somewhere.
I know on the ISC CAPS injection pumps are even more demanding in the filtering department than the ISB's. I called Fleetguard and they told me the ISC filter FS1022 is a 10 micron unit. Thats why I didn't have any problems using a 5 on my truck. But you do bring up a good point very worthy of investigation here.

I dont like to say that info is wrong B9Mile... but it could be. And I could be wrong too.
Here's the deal on ISB filtering. Per Fleetguard techline and their computer info system they use, I was told the following by a live person:
1. FS19598 10Micron 98. 8% efficient (also 82% at 5 micron)
the dirt holding capacity is 18 grams.
2. FS19528 (Obsolete) had the same micron ratings however its holding capacity was only 11 grams. Thats the only difference.
3. FS1023 shown on the FASS is a screen mesh filter w/100 micron rating.
I dont know what the other filter on the FASS but it must be the 10 micron one your talking about. I do know the ISC filter FS1022 is 10 micron also and has the WIF and drain at the bottom. Its spin on too.
On the 2 micron versus 7 micron issue... Fleetguard didn't have a clue where this came from. Looking at the design sheets for the FS19598 didnt say anything about 2 or 7. But basically the FS19598 is a 10 micron filter... it will trap some 5 micron stuff but 20% of it will get through.
Just me personally, I wouldnt mind the 10 micron final filter on the FASS... but I think the prefilter 100 micron "1023" is a waste of space. I'd get something down into the 30 range ane get one that had a water seperator. That way both the pre and final filters would have water seperators.

Fleetguard followed up our phone conversation with an email:
Thank you for contacting Fleetguard.
The micron information you requested is as follows:
FS19528 10 micron @ 98% efficiency - holds 11 grams of contaminant
FS19598 10 micron @ 98. 7% efficiency - holds 18 grams of contaminant
If we can be of further assistance to you, please feel free to
contact your Fleetguard Customer Assistance Center or send a
message to FleetMaster.
Please visit our homepage often at http://www.fleetguard.com
Sincerely,
Fleetguard FleetMaster
That was their email reply. They also emailed me the product data sheet for the FS1022. Its a 2 page deal describing the filter in full detail with more information about it than one person could possibly use. Not only does it talk about the micron ratings but it also talks about Hydrostatic Pulse durability at 41000 cycles @ 101. 52psi and a bunch of other stuff useless to the average mechanic... . like sinusoidal vibration of 1000000 cycles and Gforce acceleration limits of 5. 1 G's. If you want I'll try and get the sheet for the FS19598. Anyone can do it.

Thanks, Niel,
That clears up a lot of the gray areas with our filters.
Now that you have dug this filter efficiency info out of the Tech people, I feel it won't be too long until someone finds filters for the FASS head that will give a better initial filtering than 100 microns, and possiblly better than 10 microns, if they wish to use them
It would sure help everyone if Fleetguard and other manufacturers would post the filtering efficienies of their filters on the data pages that come up when you search for filter data. I'm sure they have a good reason for doing what they do though.

All you would have to do is call tech line and tell them what you have and what you want to do. They can match up your existing filter with something that will fit properly and do the filtering job you want.
I'd bet getting a 30 micron prefilter and a 10 micron final filter would be a snap. Napa filtration could also do the same with their tech line.
I use Napa Gold fuel filters on one of our fire trucks. I crossed the pre and final spin-ons we use with Fleetguard. I found that Fleetguards micron ratings did not match the Napa Golds at all. As an example, the Napa prefilter water seperator is 8 micron. The Fleetguard equivalvent is 20 micron. The Napa final is 6 micron while the Fleetguard equivalent is 10.
Either way... the filtering options for the FASS are probably "endless" since its spin-on. You can get many lengths, microns, diameters, drains, vacuum ratings, etc. Kinda like your own custom setup if you do the research.

It may not be a snap.
I'll have to check with Brad (the developer of the FASS) on Monday but I spent quit some time with Fleetguard today. Apparently the fitting for the FASS is larger than the usual fuel filter. Fleetguard doesn't have any fuel filter that will fit this size - it's to big. The standard filter is:
Micorn Material Dirt Capacity(gms)
CIM-TEK 70032 10 Microglass 25
This filter is also a 25GPM High Capacity Filter. I was told that it is a Pump Filter from a service station.
The Fleetguard filters that are listed are as follows:
Fleetguard HF 6338
Fleetguard HF 6601
Fleetguard HF 6610
Baldwin BT 372-10
Baldwin BT 372-MPG
The problem that I see with these filters is that they are Hydraulic Filters - hence the HF Designation. According to the Fleetguard folks, they haven't been rated on diesel fuel, but they said they should perform very well. Hrdraulic oil is thicker then diesel, so I don't know how to interpret the data. Obviously BRAD could have made the FASS attach to the existing fuel filter, but choose not to. I'll check with him on monday.

It looks like the CIM-TEK 70032 has a 1"-12 UNF thread size. I wasn't able to find specs on it on the CIM-TEK website, but there is a 70031 here.
http://www.cim-tek.com/300_400_Part.asp
The Fleetguard FS 1023 mentioned has a 1"-14 UNS thread size. The CAT filters in the link above also have a 1"-14 UNS thread.
So, I guess if someone wanted to use a filter designed for engine fuel system filtration, you could have an adapter plate machined up.
Not being an expert on these things, I would speculate the 1"-12 UNF threads are there to ensure a person uses these filters in the correct applications.
I see in the text of the specs for the 300/400 series CIM-TEK filters that they have a 5 micron filter available. But this has a 3/4" thread size on it.
"The 300-05 is a nominal 5 micron for greater filtration efficiency. The 300MG-10, a nominal 10 micron, utilizes a high-performance.
The 300 Series Spin-on Filters have a standard 3/4" opening required for most service station pumps and dispensers. The 300 Series Spin-on Filters are recognized by Underwriters Laboratories for use on service station pumps and dispensers.
The 300 Series Spin-on Filters are available with aluminum or cast-iron filter adaptors for standard applications. "
I think the "Standard Applications" mentioned here are service station fuel pumps.
It would be nice to be able to use any of several manufacturer's filters on these heads. This would give us more flexibility to fit each individual's needs.

Anyone got any specific pressure info on this pump/filter in high HP apps? I have read in previous posts about those running it, but have not seen specifics on the pressures. I am looking now because my fuel system, with Holley Blue and Smokin Diesel's -8 AN lines isn't holding the pressure it needs to. As I ride down the 1/4, stock injectors and PM3 on level 8, I see the FP needle trying to go below 0. I figure it's the Holley Blue not being able to keep up so I'm looking to switch out pumps. I have not heard if PE has worked out their issues yet, so I'm interested in this, if it can handle the volume.
I say all of this because it's not like my truck is fast or anything, only 15's in the 1/4, but the fuel pump just can't keep up.
Add to that the fact I have been dreaming of some big-honkin jectors and maybe another huffer.
Thanks,
Chris

Adding some photos -
I fabbed an aluminum box to cover my FASS system. It mounts to the lower slotted holes in the bracket that comes with it. The bolt's are welded together inside so they won't turn.

FASS Fuel System
I would like to address the installation of the FASS System. We are changing the mounting bracket to adapt to shortbed and longbed 1994 and up Dodge's. Our difficulty came not from mounting to a longbed but to the shortbed's. We have now solved that problem and it will mount in about 1. 5 hrs. Another problem we have address in this same category is that we will have pictures in our installation manuals in about 2 weeks.
