I forget where it's from.

Thanks! Now where was I? Oh yeah, I looked on Phils parts and can't find anything that looks like a clear fuel line under fuel delivery category. My line is probably original and from factory. Other than stiffness, it appears in good shape. If I replace it with clear PVC, I need to find heat resistant.
I'm going to think about this some more. F.

Fuel line
That line is PVC and is clear when new. They are pressed on to the banjo fittings and cost 8/10 bucks each at the dealer. If I were going to replace mine I would buy new.

This stuff has been working well for me, but I run WVO not biodiesel. I think it is fine for both.

That looks like good stuff.
Frankie, when you change your hose, it's better to carefully cut off the old one rather than try to pull it off. The material is probably so stiff that something else might break first or it would slip suddenly and you could injure yourself. Rather than transparent PVC hose from the hardware store (good for water), has anyone looked for transparent fuel hose at an auto parts place?

Viton is not rated for pressure PERIOD. Use it only for replacing soft lines.

That hose can be replaced by any type of hose, it only handles the pressure from the lift pump, I replaced my with rubber hoses for a cost of about $2 about 1-2 years ago, no leaks or problems. 30K miles.

That (formerly) clear hose is probably Nylon 6. It's not PVC. It was factory installed on the banjo fittings and is very hard to remove without damaging the barbs on the banjo fittings. You will most likely need to splice in the solenoid valve anyway on a WVO conversion. The best method that I have found for splicing in is to cut the tubing about 1/2" away ftom the barb leaving the stub on the barb. You can then slip a 3/8" fuel line of your choice over the stub and barb and clamp it.
For the cigar hose, I would use either soft Viton or Silicon tubing.

WD8-
Morning all- That sounds like a great method to cut 1/2 inch from barb and leave the stub intact AS long as the clear line doesn't crack leaving minute solid particles in the process. That would be the only disaster waiting to happen. Jeremy- your safety comment is duly noted, thanks. There is not a lot of room to work with there. WD8 - I respectfully disagree about replacing the cigar hose with viton. I read that the cigar hose is that special shape for a good reason. Something to to with handling the pulsing of the fuel. Viton hoses do not come in that shape yet. I'll wait until I see leakage from the cigar hose before I have to replace it with a regular shaped hose. I hope that viton hoses come in that cigar shape soon. Frankie

Notice that there are a lot of different opinions flying around this thread. Interesting.

PVC is NOT usually mad of rubber. That braided mesh stuff would probably start sloughing off regardless of what the tubing is made of, if in contact with biodiesel/WVO. Very bad for the inj. pump!
I don't think that would be the way to go on this little project. F.

The fuel lines in and around the injection pump are made of a material called Tecalan. It is pressed onto banjo fittings. You must buy them new from a dealer if you need new ones, otherwise it's best to just leave them alone. WVO/Bio has no effect on them. I'm not so sure splicing into them is a good idea, since that could introduce air into the system or leak quite easily.

Cigar hose
The cigar hose in my '85 came with the car so I don't know the age....not old, not brand new, by the looks of it. It has had B100 in it for 9 months/12,000 miles and no hint of a problem. Most "modern" (1990s and later?) rubber hose materials will withstand biodiesel. In any case, failures are not violent and catastrophic, unless you're one of those persons who never looks at their engine bay. Failures involve softening of the rubber parts, oozing of fuel, etc., over a period of months or years.
I carry a spare cigar hose, however, as you should also for any of the unique Mercedes parts that are inexpensive and easy to replace on the road but make life miserable when they fail and you don't have the spare. (There are several good lists of such things to be found in this forum. Search "spare parts" or some such phrase.) All these little parts fit nicely in the space around and under your spare tire. In fact, the showing of such a kit of spares, installation tips, and why each one is nice to have would make a good DIY for our next GTG. I'll post it. Jeremy
