Mercedes Diesel Return Line Replacement - OM617

#impalamansgarage In this quick video I replace the leaky diesel fuel return lines on the OM617 5 cylinder in my 84 300SD. If your fuel injectors are looking pretty wet these days, it could be something as simple as leaky return lines. They are simply cloth covered rubber hoses and they get very hard and brittle over the years. Parts: https://www.pelicanparts.com/More_Inf... Tools you might need: Lineman pliers or long needle nose. Get yourself some specialty hose pliers if you want. I didn't have a pair. (insert joke here) Retractable razor blade. (one of my favorite tools) flat blade screw driver. Tape measure. (Or you could just hold the old and new tube side by side to measure.... but I like measuring stuff with a tape to know what the real dimensions are) #Mercedes-Benz #OM617 #300SD #300D
