Question of economics-
If a 2-micron filter in-line before the oem filter at an initial cost of about $110 with a element replacement cost of about $12 is improving filtration by a factor of- say for purposes of the question- a factor of 2...
and consequently the oem replacent filter is expected to last at least twice as long (hypothetically) at a replacement cost of about $56 according to my dealer...
will the efficiencies from an economic standpoint support all the extra expense of going post oem?
My assumption is that the assembly will be costly as will the replacement elements and we know that the burden of the filtration will remain on the already costly oem as primary.
Now I know someone is going to say "if it saves you $6k injectors, etc, etc, etc".
I guess the real question is how much insurance am I really willing to buy? I think the 2-micron in-line primary will be very effective compared to the oem.
Can't wait to see the forthcoming test results on Todd's Stanadyne.

Trace,
My FM-100 was only aobut $90 and the OEM filters are only $20 from Kennedy.
Maybe this helps.

I got some information from a Detroit Diesel shop today about Davco Manufacturing. They sell
fuel filters for Detroit and other diesel engines.
I went to their site tonight and found that they claim to make a filter that works to 2 microns.
Here are the links it does have an interesting demo they do on there site called "Seeing is Believing"

filter model 232:

Just wondered if George has any info on this or if anyone else does.

Economics will not be a major factor here. The cost will be in the mount/filter assy for the secondary filter which should last a year or better. Element cost will be reasonable as well and in the $35ish range. The OEM filter service intervals will remain the same.
-
John,
The test results sound good. Are there any pictures of the prototype? What kind of secondary
filter are you using? I'm kinda coming in on the tail end of things and couldn't find your filter info.in the search.
My filter installation is on hold. Was kind of waiting to see how all these ideas would shake out. :eek:
-
srubrn,
Thanks for the correction. I hope John will be able to put a
package together, cuz he'll have a new customer once
it's ready.
-
a bear,
Can't disclose the details just yet as they are not set yet. I DEFINITELY will not set a release date judging by the critical nature of this crowd :eek:
-
Hey John, if you need a Beta tester out here running this Sweet California (Dirty) Crude, let me know. I know you have a short list of "locals" standing in line back there, but for Nationwide Coverage you gotta branch out LOL [img]smile.gif[/img]

ardmore,
Im using that filter but it's mounted under the hood with no lift pump and have had no probablems with it.

TraceF,
Sorry, I didn't see your post.
CC is many miles miles from here About a two hour or so drive.CC is at the end of hwy 23 in Venice La. and has some awesome charter Boats that can put you on the Tuna, especially if you go out at night. Slidell is where I-59 I-12 and I-10 meet. about 15 miles northeast of New Orleans and 10 miles west of the southern-most west border of Mississippi. You will have to pass through Slidell to get there coming from Fl. Are you hauling your own rig down or are you chartering. If so with which Capt. I enjoy an occasional trip outside but mainly run my Bay Boat around the shallows of Delacroix for Specks and Shell Beach for Reds. You can't beat fresh Tuna (we try to eat it all in about a weeks time). Once you freeze it it's just not the same. They are slaughtering the specks down in empire right now in a few choice areas.
Shoot me an e-mail b4 you pass through.
-
pepperidge- Taking my own boat. :D
Not much into spec fishin but love the striking fish and agree with you on the tuna steaks.
I put CC and Slidell together because of a boat dealer ad. Maybe he has a branch in Slidell.
Thanks! [img]smile.gif[/img]

JK
Keep us informed. I for one am interested in your solution to this.
-
jcopeland,
I am very interested in the arrangement you used to adapt the CAT 2 micron filter into the DMAX system.
Please e-mail me at skih2o@carolina.rr.com with further detail.
Thanks and regards,
T.D.

jcopeland:
Would you please email me at
dndstarr@shaw.ca
I am very interested in your CAT filter
hook up.
I have been trying to find time to visit CAT here and see just what they had to offer in
using their filter between the OEM filter and the pump.
thanks

jcopeland,
Would appreciate an email from you on CAT Filter location. Email Ld1440@wmconnect.com

So every time we take a trip....... I have a mental picture
of this "sandpaper" fuel easily passing thru my filter and
scoring my injectors. Not a nice thought. :mad: :mad:
I thought for sure that with this long Holiday weeked, John
Kennedy would have figgered out how to solve the problem
and have his unit for sale to us. :D :D

56Nomad,
I have 3 different machine shops doing bids/prototype mounts, but until I get a couple more out/installed/sampled and can prove repeatability in the handws of others, I can't say much...
-
Well I am waiting on a fuel sample now that I sent directly to Stanadyne from the FM-100 on my truck. If it checks out ok then I am going to send a second sample to George Morrison that I took at the same time to qualify the results. For all of you on the side lines chomping at the bit, hang on, results are near.
-
Schwing! Music to my ears!
-
Got back some results today and it was not exactly what we were looking for. It's possible that my sample taking technique is the issue. After talking to Stanadyne's engineers, we have a way to take the samples that should give us the results we want. I am taking the samples again tommorrow after I add a little more hardware to the filter setup to better facilitate the sample taking. I feel very confident that the filter is fine and it is my technique that is in question.
