Fuel Leak 1984 300sd
Hi all, I have a fairly new to me '84 300sd. I just noticed today that it has a fuel leak. I noticed a while ago that I could smell diesel when walking around the car, but thought little of it. Today, I saw spotting where I park. There is diesel fuel dripping down the A/C compressor. Does anyone know where the leak might be? Any common places on these cars? Thanks, Jack

There are a number of fuel lines in the area. It could be a hose, with the car running, inspect closely, yet carefully.

I looked more carefully, and it appears to be coming from the #1 (closest to front of car) injector. Possibly from where the fuel line enters the top of the injector. Is there an o-ring I can replace? Or are they compression fittings? Thanks

Typically that kind of leak is coming from the fuel return lines. Does it look wet?

If the return line is a black rubber line, then yes, it does look wet. But there is also fuel right near where the metal line goes into the top of the injector. Still just replace the return line? Thanks

Yes, as the fuel will weep around all over the place. Do this first then check again.
One meter will do the system, from the fuel filter to all the injectors. Be aware the last line has a stopper of some sort, you can reuse whatever is in the end of the line now, usually a rivet. This is not a high pressure line, just a return back to the tank. The lines simply push on, no clamp. Be careful when removing the old ones, don't nick the injector nipples. When installing the new ones, I dip the end in motor oil to help them slip on.
