I am going to have to try this at home. -cth

Hello.

I just successfully replaced many old hoses on the engine including two NLAs. I have not used OEM hoses sold per meter as thy are overpriced and you only need a small portion of it.
My local MB dealer offered me N900271012018 for 34 EUR/m compared to Semperit FKD - R 12/19 I got for 2 EUR/m!

1) For NLA A1098310294 right side heater hose I successfully used part of ORIGINAL IMPERIUM 227435 aka HYUNDAI 973210X300. For the left side I suggest using original MB.



2) N900271012018 12mm ID hoses replaced by parts Semperit FKD - R 12/19
3) N900271018036 18mm ID hoses replaced by parts of MEYLE 019 500 0475 (22mm OD = better to fit to cramped places like next to injectors under intake manifold) or ORIGINAL IMPERIUM 2507/C (24mm OD - more robust, I used that for all water connections and to connect injection pump air to air filter box)
4) N900271032008 32mm ID hoses replaced by parts ORIGINAL IMPERIUM 5508
5) N900271038025 38mm ID hoses replaced by parts ORIGINAL IMPERIUM 5510
6) N900271042012 42mm ID hose replaced by part of FEBI 100353
7) Scavenger pipe to throttle body A1279970382 replaced by cut out of VAICO V30-0667 aka A1110181082

8) To replace NLA  A0089973182 you may use part of A0079977782. I managed to get NOS A0089973182 but A0079977782 was used on my car by previous owner.




300SEL 6.3 #1285 (1969 EURO version)
300SEL 6.3 #5346 (1971 US version with engine KO)

Warning!
I just got 210 832 27 94 OEM hose to replace NLA 109 831 02 94 and it doesn't fit. There is no way to make it fit by cutting it. It's just too short. I'm considering using two peaces and some coupling.



300SEL 6.3 #1285 (1969 EURO version)
300SEL 6.3 #5346 (1971 US version with engine KO)

Update - As per Tom "Scavenger pipe to throttle body 127 997 03 82" is NLA, but it has been replaced by 130 997 01 82D

Aaron, the reason I asked you to send an image and reconfirm the part number was because
a) I can not find the part number you provided
b) When I sent the part number to Classic Center, Tom corrected it and showed me a hose with 109-831-05-94
c) The hose being sent is an L shape. With part number not matching with the one you listed an image would help me compare the hoses

Hope this clarifies any confusion

I'm very sorry for the confusion....in my original post I typed the wrong part number. The number Tom gave you is correct. I simply had fat fingers for some reason. I'm rather surprised that the 3.5/4.5 hose didn't work, as I've used that hose on 6.3 cars on many occasions. Regardless, it seems that you've found a hose off of a W210 car that will work just the same, and I'm very happy for you! :)

Ok here goes. The hose sent by classic center is a bit short so does not work. I had ordered a hose from ECS tuning
Link: https://www.ecstuning.com/b-elaplast-parts/heater-hose/2108322794~ela/

This hose has an ID 1mm (16.6mm) smaller than the one I received from Classic Cente (17.4mm) but has the correct bends to fit like original. You will have to cut some unwanted bends to take out what you want. The best part is this is for MB so is almost original fit.

While yours is an early car, it's not early enough to utilize the early hose (up to chassis 000151) which uses two of the 109-831-03-94)

As it turn out, the hose you need, part number 109-83-02-94, is no longer available. However, I believe that the hose a 4.5 or 3.5 uses will suffice, part number 109-834-05-94, which is still available.

Thanks Aron for the update, can you please confirm the part number I can not find it on any parts website. Also if you have a picture you can upload, it will be a great help.

What exactly are you wanting a picture of? I'm not sure how else to confirm what I stated other than quoting you the footnotes like I did.

Well I finally got hold of Tom at classic center and he is sending me the hose. It is “L" shaped. Once I get it I can provide details. As a matter of fact I had found .75" Grant’s "L” shaped hose and have ordered it. If the one coming from Classic Center works then the Grant one will be returned

Here are pictures of the heater hoses. Left side hose is 1098340394 which now subs to 3135060435 and is readily available. Right side hose is the NLA 1098340294. I tried twisting the 0435 hose 90 degrees and it appears it would work perhaps having to trim off a bit. It would be nice to see if the 1098340594 hose mentioned by Aaron would be a better fit. Can't find a picture of that one.

Jim, thanks. It is different. I have the picture but am unable to upload. If I may explain it is almost an S shape but the top end is at 90 deg to the axis

No I just trimmed it. As I said mine is a very early car.

Thanks for the update. Did you have to cut it and insert a metal pipe to twist the ends?

I think that is all the water hoses.

FUEL HOSES.

Fuel pipe to filter 109 476 03 26
Filter to motor 100 476 16 26
Motor to return line 109 476 01 26

That's all I can think of at the moment. All these clamp numbers are from my old Parts Catalogues will upgrade to current M-B clamps. A lot of the hose part numbers will as well. As you are in Europe, I guess you will deal with the Classic Center there or the dealer. If you have trouble, get back to us, because we can get upgraded numbers from Tom Hanson at the USA Classic Center of from our own records.

Some of the high pressure lines can be rebuilt reusing the end pieces. The oil line to the air compressor and the return fuel line hose are the most important if they have not been replaced already.

I am trying to get the right side heater inlet hose and classic center keeps on sending me a hose that is duplicate of left hand side that is looks like a S shape. You guys have any suggestions?

Hi Art, Oliver and others,

I recieved Olivers package, And WOW, he shipped me a large box FULL of different hoses, water-hoses, air-hoses, high-pressure hoses and what not. And all that as an early christmas-present. [:D][:D][:D]

I'm now taking stock as to the state of all the hoses I can make out, and I can use the spares Oliver sent me.

I guess that if I had to buy them all seperately, I would be looking at a few hundred euro's, so Oliver is going to get very drunk from all the different Belgian strong beers I'm going to present him come next spring! [}:)]

Art, I won't be coming to Australia any time soon, but you deserve it too, for your work, and your patience with me. THANX!
