I am trying to find the correct replacement fuel hose that connects the hard supply line from the tank to the hard engine supply line. The hose says "eco veritas xliner 20473A", but I cannot find anything online and am not sure what the correct ID for that hose is.

any help is appreciated?

The descriptions are slightly different but do any of these look correct?

 

That bulk line looks too small, ID wise. Also, the hose connecting the engine to the tank lines are not braided. They are likely close to 5/16 ID or 9mm maybe. I have already replaced the formed hoses shown in that picture as they have part numbers as you can see. Those were bad, cracked and leaky. The others are also original as shown by a date stamp of 2009. I'm getting them cleaned up so I can be sure they are not leaking, but I'd like to get some replacement hose so I can swap them at my convenience. All my searching though has yielded no information on the correct inside diameter, as installed at the factory.

Thanks again for the effort!

 

Looks like 3.5mm ID and 7.5nm OD.

I don't think so. It's got to be bigger than 3.5mm ID. it's more like 9mm.

I wish there was a document from Mercedes that specified it.

 

Try this. Its in Russian bit with Google Translate function in Chrome you can read it in English. There are plenty of diagrams and youll be able to find the part number. It doesn't look like its that expensive - might just be simpler to buy it from MB? Or just go to an auto parts retailer, cut small sections of all the hoses that might fit and you'll probably find the right one.

Thanks! cool to finally see part number for reference. Now to find it here in the US.

I know i can get some length of hose and stick it on there, but I like to try and find the exact parts and sizes to be sure I have good seals etc.

 

MB don't stock it?

 

Well, that was easy. An initial google search show lots of foreign sites, but then I just typed into "import parts direct" search and they had it.

Thanks so much for helping me find this!

 

I searched the my usual sites before but they had no pictures or description, so I had no idea if it was the correct hose.

 

Now I can also find all the little plastic wire / hose holders that have broken over the years!
