Hi,

I just purchased an '83 300 D Turbo. I'm really impressed with the car and how well it rides and feels especially considering how old it is.

This is my first MB and my first diesel, so it's really a learning experience.

I've noticed a strong fuel smell and I've noticed that one of the injector return lines is moist, and the associated injector is wet with a little fuel running down the engine block from that area. It's not a lot, but everythign is a bit moist. From what I've read, I need to change the injector return lines, which looks like an easy-enough job.

QUESTIONS: Do I have to get the original MB part? Does my local AutoZone have something I can use? What's the ID of the tube? etc.?

I'm happy to use the right part, but I want to to it today, as it stinks and is giving me a headache and sore throat (it rained this morning so the sunroof was closed and the windows mostly up!).

Thanks for any info!

The correct part is available from suppliers other than the dealer. Whether AutoZone will have it is another story altogether.

A "generic" replacement hose may, or may not seal properly around the nipples.

Also, be very careful in removing the old lines. If you cut them off the nipples, be sure that you do not nick the nipple in any way.......or you'll have a permanent leak.

Installation requires some patience to get the line all the way down on the nipple. Leave the hose in the sun to warm it up for this endeavor.

Is cutting the old lines the best way to remove them? I have tried pulling them, but no luck. Do you just cut through the braid a bit to loosen them??

I purchased the return hose from the dealer, 15.00. Tried a few auto parts stores, the all the auto parts hose too wide to get a good seal on the injectors.

I used a single edged razon blade to cut mine loose.
Went to a foreign repair shop, and asked them for some hose since the rubber stuff from a mcparts store leaked.
