W115 300d (1976) Spin on Fuel Filter, Help!

[jondoe0069]

Hello,

I ordered the secondary fuel filter for my 76 300D and what arrived was a soft filter and not the spin on type. My car seems to have the spin on type of filter with a drain plug at the bottom and does not have any type of additional housing to drop a soft filter into. Please see pictures below.

I went to the auto parts store and they said they had a spin on type filter in stock that came up when they searched my year/make/model, but that filter was shorter and the bolt hole on top of it was too small for it to spin onto my set up. I also had them check newer OM617 models and it showed the same filter. When they checked the 75, the soft filter came up.

Does anyone know the right filter I'm supposed to use? Part numbers, manufacturer? Does my set up seem to be modified? The original filter was a Napa filter, but the part number had been wiped off. Please help!! Thanks!

I'm doing the obvious and contacting Bosch by phone tomorrow. I've also emailed them today. They should have an answer for me since it is their filter head. I will update this thread when I have info.

I think I found the info I was looking for!

Got this answer from Auto Haus AZ

The Bosch filter part number you provided, 0 450 133 009, is actually a Volkswagen fuel filter used on the 1982 Quantum and 1984-1985 Vanagon diesel models.

Because if its limited use, this filter has been discontinued and is not longer available from Bosch. Luckily, the earlier Volkswagen diesel filters were nearly identical and also fit any application that used the 0 450 133 009 filter. Hopefully, this will be the case for your Mercedes.

The filter we stock that replaces the Bosch 0 450 133 009 filter would be the Bosch filter part number 74 101 or Mann filter 068 127 177B. Both are readily available and can be ordered through our website. Just use the link below or enter the part number into the part number search at the top of our website.

Looking at some pictures of the engine bays from those cars, it seems to be the same filter head. I will order it and report back when I install.

I ordered Bosch filter part number 74 101 and installed it this weekend. Fit perfectly!

Just wondering... That ff housing looks identical to my vw rabbit 1.6 ff housing. Did someone change that to vw housing, or is that stock fot that year?

My 75 240d has a canister filter.

If it was a Mercedes Filter Housing it would have a Mercedes Part Number on it.

It is a VW Rabbit Fuel Filter Housing from the 1980s (I pulled it off of one from the Junk Yard). I have one in My Garage.

[NickCox]

Interesting. I have two of those vw housing around.

Now I'm wondering what the what the efficiency difference is between stock and vw spin on. T

[jondoe0069]

It is a VW housing. I got the car that way. I'm not sure if it's more efficient, but I assume it is since that's the style of housing/ filter they went to in the later models.

It is a modification by a previous owner.

It is NOT more efficient.

It is cheaper to make the flange with disposable screw on cartridge.

The full aluminum housing uses the same filter element (slight dimensional changes to fit each application).
