fuel lines needed
 

I have a problem with one line leaking it is the line that comes from the fuel pressure regulator to the fuel distributor. Can not find it on any parts group, any and all help is greatly appreciated.

jnt:

It would help if you:
1) State what engine is involved
2) Showed the line in place

so very sorry but you are correct, the car is a 1991 190E 2.6 the fuel line is very hard to see when installed but any one who has worked on these understands, the description in first post is lacking so here we go. this line is hidden because it travels toward the right side of the engine and the curves around the back of the dist.and under the EHA then up to the bottom half of the fuel distributor. hope this helps!

Part# A 103 070 16 32

Description: LINE from Diaphragm type dashpot to fuel distributor

Found in EPC under 201.029, engine, 103942 M 103, 103.942, 07 injection, 075 Injection nozzles, lines, etc.

The question about a pic of the line in place arose because the line illustrated appears to be smaller in diameter than the line between the FD and the FPR, and because the FPR is downstream of the FD (it is in the fuel return line) in a CIS-E system, hence the line is from the FD to the FPR.
The line in the pic looks more like the line that feeds the Cold Start Valve.

yes one picture is of the hard line that goes to the csv the much larger line is the one I need. fd to fpr you are correct. 865sp300e gave me some text and part# but all I got was some wood working equipment.

Quick solution: Junk yard. You can find one there for dirt cheap and quicker to obtain. Just a quick question: Did you try removing it, cleaning around the threads and the tip and reinstalling? Just wondering since there are no rubber o-rings to fail, I'm curios as to why its all of a sudden leaking.

pressure is pushing past the collar and or tip and the line then sprays out at the collar and line. I think the true problem is that the line is not tight against the tip or nozzle

Part# 103 070 16 32 is item 56 in the attached diagram.

Ok I see the line but who would it come from? I have not found this item in the parts department of pelican parts?

If you Google "Mercedes fuel injection line 1030701632" the first page of search results show mostly online vendors that would be able to supply the part you need. Cheapest site appears to be selling that line for about $40 and range all the way to slightly beyond the list price of $56 (plus S/H, I assume).

It sounds strange but I've had a bit of luck hunting obscure parts down for decent prices on Amazon.

Phil (R.I.P) from a sponsor of this site was an invaluable resource for any parts. I likely speak for most all of us, we really miss his expertise, professionalism, and wit.

Phil is the most missed person in all my automotive requirements we had become very close I still suffer from his passing, I have persons for ford and a chevy man plus a chrome shop in Pa. well to find a parts man is not hard, but to find one who will go the extra mile and keep that up beat humor and never forgot to call you back.

just-n-time, call the Parts Department at a MB dealer. Have your VIN handy, because most reps look up parts versus the VIN. Pelican Parts doesn't carry specialty parts like the fuel line you need.
