Where Can I Get a Fuel Filter Assembly?
 

I'm working on my WVO conversion and I cant seem to find a decent fuel filter head. The one at greasecar looks ok but it doesn't look like it has any mounts or screwholes. Can someone please point me in the right direction or tell me how they did it in their W123? I should mention that I'm using coolant hose wrap around the filter as Dana suggests in his plans.

Junkyard, forsale forum here, car-part.com. Probable even the buy parts link at the top of the page.

I'm not loooking for one to replace my regular diesel filter assembly. I need a second, aftermarket, stand alone one that can be installed somewhere in the engine compartment. This second fuel filter assembly will be used for WVO. I have found a few online but of the unheated ones I've found they don't have mounting brackets or screw holes.

I'd go into the biodiesel/wvo sticky and look there.
I'm sure fleetguard and such make em.
cat as well I believe.

I've got a 123 fuel filter housing if your interested. PM me if your interested. NAPA also sells a fuel filter housing, that I've used for VO conversions. I'm trying to find it on their website. Be right back:D

--Can't find it on there website. But I know they have filter assemblies.

The 123's that I've helped out on the Greasecar installs had them mounted to the drivers side wheel well. Metal screws that hold on a clamp mount that surrounds the filter. Don't those come with the filter head and a different size filter? Then the copper tube that carries the antifreeze runs around the filter. I'm pretty sure that's how it was done. I was always the one who worked on the tank installation in the trunk, but it seems to me the solenoids and the filter were mounted just ahead of the firewall and fuse box on the fender wall.

Something like that. I'm just having a hard time finding one that comes with a decent mounting option. I was hoping someone else that has this conversion could tell me what they did.

On eBay they have various sizes of filter heads.
It is better to pick what filter you want and then look for a Filter Head with those thread sizes.

Racor Filter Housings are expensive but they have interchangable Filter Elements in different Micron Ratings.

VW Rabbits ( uses a filter with about twice the Volume of the Stock Mercedes filter at 10 Microns and Baldwin makes a filter with a drain at the bottom that will fit it that is somewhere between 2-5 Microns) and of course your Mercedes Filter Housings can be used. But, it is better to decied what Filter and Micron Level of filtration you want and then look for a housing.

I'm thinking five microns. I've read that 10 microns is ok for these cars but better safe than sorry. I was about to get a racor but I read that the racor filter heads have a tendancy to leak; anyone have that experience?

I mounted a Stanadyne FM 10 on the support behind the left headlight.

Anyone else had any problems with racor? I like thier product but not if it leaks.

How about this? It looks simple, but it's designed for engine oil, does that matter?

Can I get any spin on filter for this that has 3/4" x 16 thread?
Will this be ok with WVO?

There is this option as well. http://www.greaseworks.com/store/product_info.php?cPath=21_38&products_id=427

Yes but that's really expensive and also has electric heating already. Whatever that head is looks great I just don't need the heating element; I'm doing that myself. I just need that head element that the filter screws into. That one in the picture even has screw holes that would make mounting easy. If that is available alone please tell me where.

This filter head mod has the same threads that is used on the Greasecar kit. And you can adapt your heating unit to it.

That seems a little complicated, there has to be something out there I can buy, like that oil filter head from Summit. Will that work or will it not make a tight seal with a diesel/wvo filter?

Your local autoparts place may sell the sameone.

Concerning a 5 micron Fuel Filter.

Below is a thread where one of our members Deliveryvalve had stock filter Housing mod he wanted done.
The mod was all his idea but I did the threading.

It uses a Baldwin BF7591-D; the D means it has a drain screw at the bottom to drain off accumulated water. This filter is threaded for M16x1.5 threads and that is the same threads used on the older VW Rabbit and Volvo Diesel Fuel Filter Housings.
So while I gave the below thread for reference purposes you could just get a older VW Rabbit Filter Housing and use that.

Post #12 has the micron spec sheet on the BF7591-D

Ok, i think i'm close. So is 16 x1.5 a common size for spin on fuel filters? Wix makes some decent looking heads as well but I need to decided on the size first.
The stock spin on has 14x1.5, is that right? I don't think wix makes one that big.

The M16x1.5 threaded filters are common to the extent that they were used on the older VW Rabbit and other VW vehicles that used the same Engine.
However, the stock VW Fuel filters have the same 10 nominal Micron Rating as the stock Mercedes Filter but the Filter is double the size and it has a screwed drain at the bottom of the Filter.
WIX (I used the the NAPAP virsion) makes their version of it and that is the one I used to use on my Volvo Diesel.

The Baldwin Filter I was speaking of is not so common. You would have to get it at a Baldwin Filter shop or if you live somewhere where they have Tractors and Farm Machinery they ma sell it. But that would give you the lower 5 Micron filtration.

Below is a pic of a VW Rabbit Filter and Housing. The Outlet in the middle top of the Filter uses a Banjo Bolt and Banjo as does the Inlet that you can see in the Pic. I could not find the Banjos and Banjo Bolts before I took the pic.
