Fuel lines on a w126

[Monomer]

I'm a bit confused.

theirs a total of three lines running from the back. One of which I can identify as the send - it go's straight to the fuel distributer. Another line also hook into the distributer, but get sidetracked into what looks like an AC line.

Is this MB's way of cooling fuel?



Here's what I'm trying to do: I broke all three lines (in various place) that run right by the driver side wheelwell. It seems as if the rubber bushings hold in water, because every line that touched one is rusted - and most rusted through. So right now I'm "patching" everything. I noticed these lines run right nextto the exaust manifold, which is a shame because I cant be cheap and splice a rubber line in (which I did before noticing it's placement) I'm going to insulate it with fiberglass, no worries.

PS the bushing have to be a design flaw. I suggest spraying them with a rust-inhibiting paint (POR15) and then covering with spray body undercoating. this is NOT fun.
