Fuel lines to enigne bay W124 95
Folks, I neglected to label the steel fuel lines that run from the tank into the engine bay.
I ASSUME the lower one is the inlet (supply) and the upper is the return. But I dont like to assume. Which is the feed and which is the return? tia.. Last edited by WINGAS; 04-22-2007 at 07:20 AM. |

I'll run out to the garage after I finish my blueberry coffee cake. I have an '87 so the lines are probably the same.

Its vague enough to be useless!
Well, when torquing down the injectors, I must ahve pulled one of the return lines off. A few minutes later I see that that hole , #6, is full of fuel. ![]() So I reckon that I had the return/feed lines crossed as the retun lines filled with fuel. Tonight I'll put the car on stands and take a gander underneath. Suppose it could have filled through the return line ( the fuel tank is full btw). Is there any DEFINITIVE way to know which one is feed and which is return? Other than being carful to frickin LABEL THEM when I disassembled it in great haste? ![]() |

Check inj #6 and make sure it has a return line plug installed on the last nipple.

Ya, thanks Terry, I cut the old "slug" out and put it it new line.
Well, the good news is, when I swtiched the fuel lines, the rest of the system primed a bit, fuel to the preheater now. So it looks as if the feed line runs through a valve 203 after exiting the tank and then it looks like ( in their "impresionist drawings" ) that line #14, goes into the preheater. FOR THE RECORD, as they enter the engine bay, the LOWER line is the feed line, the UPPER is the return on a 95 E300 D 606.910 Different than Chris 87 . Saw no valve outside the tank, but the feed line plugs into the bottom of the tank. Last edited by WINGAS; 04-26-2007 at 09:41 AM. |
