Hey folks,

You know how it is. Older fuel hoses. Dried and cracked.
I've searched the forums trying to find an answer to this - no luck. . What size are the supply & feed fuel hoses that connect to the fuel filter? They are definitely 2 different sizes and most likely metric. Lots of talk about changing fuel hoses but nothing definitive regarding the actual metrix ID sizes. Also what size are the injector return line hoses?

Prefer to use straight hose and just make it work with gradual bends as needed without kinking. I feel Like I don't necessarily need to use the OEM moulded/bend hoses (and they are a bit expensive too). Pelicanparts has a great selection of straight metric hose, I just don't know which size! Does anyone know? (Scroll to the bottom of this page to view the fuel hose selections: https://www.pelicanparts.com/catalog/SuperCat/3839/MBZ_3839_FULFUL_pg1.htm#item1

Thanks!

First, here are the hoses:

648-070-12-81 Filter to pump
648-078-07-81 Filter to fuel tank

Second, I would not mess around with saving a few bucks...it's just not worth it. For $25 you can pick up both hoses from MB (just find a dealer with online parts business...e.g. mboemparts.com).

The clamping is another issue...

Thanks for the tip Shertex. I'll order them from mboemparts.com

Edit, what about the return hoses? What size are they?
