The return lines at the fuel tank are leaking on my 1978 300D. Can someone tell me what size hoses I need? I know one is a braided type. I just need to know the MM size. Can I get these at a parts store, or do I need to get from MB?

Thanks

Jeffrey

MB uses both 7.5 & 8 mm fuel lines. Most part stores have 5/16" that is very close. MB suggested list for a meter of the factory line is $12. (916030-000527) is the part number
