Can anyone add any additional info? I would like to replace the 2 lines that cross over the left side rocker cover. One is high pressure from the fuel pump. the other is the one going to the suction line cooler for return to the tank. It seems like they are pushed on to a steel line with barb end on the line. Do they need to crimped in some way? The mb dealer has the lines with fittings attached, very expensive. Is this the same fuel line shown on the forum buy parts. Thanks Topgun
