I am having a issues with the car shutting down while driving. If I put it into neutral and press on the gas petal it will continue to run. I suspect it is a fuel line problem but I cant seem to find the fuel filter. Would anyone know where it is located?

I believe that there are actually (3) inline fuel filters. There's a fuel strainer in the gas tank, a filter before the fuel pump, and then a 3rd filter before the fuel injection.

Hello Tony,
The main fuel filter is located in a canister located on the left engine support. it is a short distance in from the motor mount on the left side. There is a 13mm bolt directly in the center on top which holds the canister in place. The 13mm bolt comes out the top and the canister and filter will drop out the bottom. The job is much easier with two people. There is a rubber o ring seal used to seal the filter (square profile).

Don't confuse the oil filter canister for the fuel filter.

Here is a picture Tony.

Hard to believe I ever had an engine that clean! With mine, both canisters are vertical but generally in the same place as Joes. I also agree having three hands is helpful when changing the fuel filter -- its tricky to get the seal to stay put while screwing the canister back on. I have used a dab of vaseline which holds it just long enough...

Joe - thanks for posting that picture for Tony! I was trying to find one - but hard to get the right angle while the engine is in the car - but you have solved that problem! I have save your photo in my files for future use - and I agree - my engine doesn't look that clean!!

My kitchen is not that clean

Yes, the engine is fresh and a pretty little gem. Let me know if you need any other pictures before I install it in Alfred's 280SL.

Hi, Joe,
A picture of the other side of the block showing the throttle bracket on the block and water drain plug please.
And later, fuel injector pipes and location of the clips that hold them together?
Thanks
Naj

Hello Naj,
Here is a picture of the right side of the engine. Everyone should be aware that water drain plug and the linkage pivot details on the 230SL engine may be different.
I'll send a picture of the fuel pipes later. Another good item to photo document would be the location of the rest of the plumbing, and attachments (auto trans lines, metal oil cooler lines, battery cable and all the attachment hardware and the locations).

Just a caution when changing the fuel filter, FIRE is always a possibility. Keep a fire extinguisher handy, preferably something like a Co2 or Halon type that won't do more damage than the fire like dry chem will do. Watch out for sparks like from a work lamp or the obvious, a cigarette. Smokers are oblivious to this danger, you must watch them carefully at all times, they will light up anywhere anytime without warning. You may also want to unhook the battery when opening up the filter to avoid a possible spark. There will be gasoline spilled. Be prepared.

Just a little more related information:
Here is a picture showing the standard fuel filter (on the left) and fuel filter O-ring for our cars. The one on the right may be the break-in filter? Not sure. I once ordered a regular 113 filter from Bud's and they sent me this. The correct part number is written in pen on the box, but the number on the filter is different. I never used it because it didn't seem right. Can anyone identify?
Regular Fuel Filter P/N 000 477 64 15
Fuel Filter O-ring 100 997 0040
"other filter" P/N 000 477 38 15
And thanks Joe for the engine pictures. I think my drain plug matches that one -- a 230 engine but a MB replacement from 1980. Many things differ from original I have discovered.

Hi, James,
The MB filter on the right is a diesel filter with a finer mesh. The correct part # is the one on the box. I could not read the # on the filter itself. 000 477 3815 was a previous #.
I have used them before, especially on my 230 SL which sat in a barn for 12 years.
The first two I changed had changed from white to brown and the filter bowl had about an inch depth of fine silt/rust dust.
In fact, I think the filter cannister on our cars came from a diesel engine heritage as well.
I would have no hesitation in using them, but I am happy to be corrected.

Thanks Naj, I guess i'll keep that one as a spare... And just to add a little more about filters: I changed mine today -- had about 5 or 6K miles on it (I think)... I was surprised that it was as dirty as it was? Should I expect to see any marked change in performance with a clean one? mpg maybe? car had been running fine although I am only getting 13-14 these days.
-
That is really dirty, mine come out pretty much loking the same as when new.

Hello,
I recently removed one of the diesel style filters from a W113 (gasoline) car. The top and bottom of the filter had come apart. I don't know if this was an isolated problem. Maybe gasoline attacks the adhesive in the diesel filters?

I was a bit shocked myself. No sludge or particles in the canister but an awfully dark element.
