Can ya'll help me out a tad here?

I'm out of town on business and won't be home for about 3 weeks. Wife called last night and said the 83 300SD smelled strongly like diesel. I had her pop the hood and describe to me what she saw. Going by what she told me, one of the injector return lines came loose. I told her to push it back on. She did. She just called me this afternoon and said the smell was back as was smoke. She popped the hood and said that so much fuel had shot out that it was running out of the hoodliner when she had it propped up. The injector line was again off.

Since she doesn't have a digital camera with her, and I'm going off memory from what I recall seeing, things are quite fuzzy.

Are these fuel injector return lines held on by a barb on the injector or are they held on by a hose clamp? Is this typical or just one of those oddities of having a car with 23 year old lines?

I do have new lines in the garage, but if possible I'd like to wait till I get home (3 weeks) and replace them myself.

Thoughts? Thanks.

I don't know about other peoples, but my are just held on by the male barbs on the injector. Mine does not have any hose clamps, or anything holding them on.

no clamp..just barbs as stated above. If your wife is reasonably handy and it's not one of the more difficult lines I'd recomend you have her change it out. Might take a bit longer but it's not as though it's an impossible job by any measure.

Hi,

I concur with Jonathan, it's an easy job... and shouldn't be left alone if the car is driven. If the car is unneeded........

I'm trying to think if my wife would be able to do the job.. I'd say yes, with audio supervision via telephone. You know, tools & procedures etc.

Cheers, MBL

Hose barbs is right- but you could always help them with a zip tie once it's on- then split one return lines will hold better until a full repair is done.
