Same, after seeing what came out of my tank. I've been trying to find an inline fuel filter that will go down to about 5 microns, to insert between the primary and primer pump daisy-chained. If that comes up fruitless, I will probably go for this. I think this mod is fantastic and great job to those who pioneered it!

What? I don't think you know what your talking about. The flow rate of filters is rated in GPM or similar. Micron rating is the size of particle the filter will pass. Both of which have nothing to do with power unless of course the filter is much to small (too small flow rate).

Anyway, I'm not ASE certified. I'm just speaking from experience of having worked on and owned these Mercedes cars and had to get my money untied up no matter what. Also, I've found that if you follow Mercedes theories as announced, you will never get out of the woods.

Here is one of the other ways I thought of to modify the filter housing that dose not use a Banjo bolt at all. You tap the top of the filter housing for a 1/2" pipe plug (use a newer style housing that uses the O-ring type Banjo bolt as it has a straight inside diameter). You make a threaded sleeve that will be JB weld epoxied into the threade bottom part of the housing. Epoxing the threaded sleeve inplace solves the problem of unfilterd fuel leaking by the threads.

i will take number 2 and 3 if the price is right. but 1 for sure. i have a 240D and 300D that these would go in.

PM or Email me.

lol. I got all the ones I could find in the junkyards.

At the local junk yard here you are lucky if the have 2 diesel Mercedesl. Even more lucky if they have not already been picked over.
The filter bases are cheap here $4.95 each but I bet shipping one cost close to $4 one way.

An interesting note is that both the old style that needs a crush washer and the new style that uses an o-ring have the same 615 092 01 08 part number.

Yes, I have an old style one from an 82 300SD and a new style from a 84 300SD (have not seen a 300D at the junk yard yet). As you said the housings have the same part number.
What surprised me was that the older style bolt has a skinny smaller 12mm OD section the extends about 23mm beyond the threaded end. I think it would have been nice if Mercedes had retained that section on the newer bolt as it is less likely to pull in air as the fuel would be drawn from close to the middle of the filter instead of at the top.

Avoid boltdepot.com, the bolts they sent me had to be repaired with a die because the threads were damaged.

I couldn't find any place that had a M16x1.5 banjo bolt longer than 30mm so I bought some 50mm bolts and drilled them into banjo bolts. The bracket I made let the filter clear the power steering brace but I had to slightly bend down the glowplug harness support bracket to install the filter. I didn't use any o-rings but I did use some red loctite on the bolt to lock it in place and seal the threads.

As was said before, it runs like normal. I actually have a tad more power which means I was due for a filter change anyways.

Not a bad mod at all, only 30 minutes to change and the police were only called once (It was 2am and somebody thought I was stealing my car ).

Only time will tell how well it performs as it loads up with crud.

Now that you have the new base setup, you now have many other choices of fuel filters.

So if it loads up and clogs sooner then your liking, you can always increase to a higher micron rating.

- Baldwin BF587-D: Has a nominal rating of 5 microns. Still better then stock, but taller and has a drain. I've used this filter many times on my Greasecar kit with good results.

- Wix Filter 33472, same as Napa 3472 and CarQuest 86472: Has a nominal rating of 10 microns, same as stock but has drain. Again I've used this with my Greasecar kit but no longer because of the obvious.

And for those that argue smaller microns = decrease in performance but still want a filter in place and one with a drain.

-Fleetguard FF5135: 16MICRONS (Sixteen Microns! This filter came with my Greasecar kit and I thought it was 10 microns originally! )

-Fleetguard FF5156: 16MICRONS (This is another standard part # Greasecar filter)


But I am sure there are others that use the same filter base type. Just do the research.

I've been using the following process to filter my WVO -

1) Settle for @ a week
2) "Pre-Filter" with flour sack cloth
3) Filter through 10 micron bag
4) Re-Filter using old fuel pump to pump "fuel" through a "Pure-One" oil filter. (Pure-One by Purolator has a one micron rating)

This fuel comes out BEAUTIFULLY!

My question:

Is there a reason a Pure-One OIL filter couldn't be used as a fuel filter? (using the modifications listed above to install the filter)

There wouldn't be any water separation (I am not concerned with that, been running straight WVO thinned with Kerosene (1:5) with no problems for over six months), but would have finer filtration.

Are you SURE that the Pure One is one micron? Their site states that they are 99.9% efficient based on ISO 4548-12 at 20 microns.

But, I wouldn't be as worried about filtering veggie oil as I would about water removal. Most contaminants in veggie oil are soft and cause little damage but the water left in the oil will slowly kill your IP. One week of settling may or may not be enough to get the water level low enough. It depends on temperature, convection currents and several other factors.

I would have to dig thru some notes, but I believe those are absolute ratings, and are considered 10 mic nominal- similar to the the wix units referred to above. I have not gotten a wix "absolute" rating, even from their tech support, so I am using fleetguard filters. at least they dont cover it up w/ nominal ratings.

but- I may be wrong.

back on track...
I have an old housing or 2 in my parts bin, and really dont care for the tiny filter these cars have stock.

so the mod requires-

a 16x1.5 x 50mm bolt, drilled into a banjo type.

Drill and tap the housing?? or is this not needed with an Oring?

some sort of bracket to clear the PS assy.

an appropriate filter.

Am I missing something??
