1M of braided return hose is NOT enough for the OM606 - PeachParts Mercedes-Benz Forum

Hoses are sold by the foot - true at auto parts stores, true at dealers.

Sorry dude, not the return hose, at least not at the 2 dealers I surveyed for it...MB prices and lists it being offered by the meter and that's how they sell it.

Not true at my dealer. Ford dealer, maybe, but not Mercedes Benz. Either you buy a meter, or nothing at all. The only exception is the coolant bypass hose, sold by the inch. Some online parts vendors even sell that by the meter!!! Ouch!!!

And the parts stores want to sell you a SAE 3/8" hose to replace a 12mm, in the case of the power steering hose.

Not true. 3/8 = 0.375 inches = 9.525MM. so, A little grease and a lot of shoving and viola. Hose fits in.

Only 2.475 MM difference. What is that between friends.

When it's a return hose in a hydraulic system, the difference can be huge. A 3/8" hose has a cross dection area of approx. 71 sq. mm. A 12mm hose has a cross section area of approx. 113 sq. mm. That means that the correct hose is 59% larger than the 3/8" hose.

Your point that numbers can be challenging is well made. Very well made, in fact. And you are to be commended for being such an easily satisfied customer. I know that the store clerks appreciate the fact that you are willing to accept whatever part causes them the least amount of inconvenience. Whether it fits or not.

It was a joke, by the way.

As to that, well, not true. I am willing to accept it in dimensions that cause ME the least inconvenience. I don't want to go down there and find that they have cut the part to their lack of understanding of my directions. Case in point, I called a shop and had them cut me out 4.5 feet of hose since they have a cutter and I don't and it was SS brainded hose. What did I get in the bag when I came home? 4 pieces of 1/2 feet hose. Yet I got billed for a stretch of 4.5 feet. That is why I make it easier on them. So it is easier on ME in the end. Call it resignation on my part to bang my head against the wall. Now I have it as easy as I can for them so they can make my life easier. That or teach them how to do their job. No thanx. I am NOT a teacher.

But that is what I am saying. And you want them to enter fractional values into the computer. Garbage in garbage out. Lets keep it simple for the guys there. If they can look out the correct part and give it to me in whole meters, I don't want to rock the boat and have them do it in inches or half a meter or whatever. I'm scared of the results. You might be presented with a bill because they transposed a decimal place.

True at which dealer? Not any MB dealership I know of.
