Replacement of the Clear Fuel Lines on Diesel Engines - Page 2 - PeachParts Mercedes-Benz Forum

Gray Market Survivor · #16 03-08-2002, 09:01 AM

Folks,

I can say that the clear fuel lines look like a real pain to replace. Of course, the one I cracked connects on top of the main fuel filter with a tri connection through the banjo fitting and the other end is cramped between the block and the IP.

I checked my old lines and they are marked DIN 73378. Can anyone tell me what standard that refers to? or does anyone have an SAE cross reference??

Since the end I cracked is right up next to the fuel filter, I am thinking of putting together two hose barbs with a union and just lengthening the hose that way so I don't have to monkey around between the block and IP.

Any thoughts??

Herb:

M-B does not have torque values for any of the banjo fittings associated with the fuel system. I would tighten till they are snug and no more - then look for leaks and tighten a bit any fittings that leak. These are steal fittings threaded into aluminum - so the least amount of torque that will not allow leaks is called for.

Gray Market Survivor:

I would think using unions would work fine, so long as the ID is not too small preventing good return flow - look at the ID of the tri-way connection for the ID you want to match or as close as you can.

I would agree the clear fuel lines are a pain to work with, especially old ones. I broke my return line right at the tri-way fitting. I cut the old line off the tri-way fitting, then expanded the remaining line using needle nose pliers so I could push the line onto the tri-way fitting, and then used a small hose clamp to secure the line to the fitting (I was only able to get the line to go over two of the three grooves with ridges on the fitting - no leaks). It was really surprising how flexible the old line was when I used the needle nose pliers to expand it, but I could not get the line to expand enough to get it all the way on the fitting - this is some tough stuff. I then found a replacement line at one of the local junk yards that was in good condition to replace the repaired line.

Can't help you with the DIN standard.

Good Luck!
Tom

Sometimes I wonder of people actually check prices before doing a Rube Goldberg (sp?) fix. I just replaced all three of my lines, and the cost for all 3 was ~$17. That's brand-new clear lines with the metal fittings attached, straight from Mercedes-Benz. The large copper or aluminum seals were $0.40 each (8 required), and the small aluminum seals were $0.15 each (2 required). Total cost was a smidge over $20 for everything. Mine were structurally fine, but I didn't like the brown color. I also prefer to see the fuel inside the lines. And since I was in the middle of a ~$3k head replacement job, and had pulled the I/P out for calibration, it seemed like a relatively inexpensive "upgrade". I had to replace the seals anyway. Now I've got all pretty new lines. I took a photo of two of the lines, old + new, next to each other to show the difference. When I download it from the camera I'll post an URL so y'all can look at the difference.

BTW - I got my parts from Wholesale Parts in GA, but FastLane and PartsShop should be able to get them at a similar price. Add on ~25-40% or so if you're buying at the dealer's part counter.

Regards,

Here's a photo of two of my new lines, next to two of my old lines. I had already installed the third one on the car:

Hey GSXR,

Do you have a contact number for the guys in GA? Internet searches didn't seem to get me anywhere.

I was at the Marin dealership this morning, they wanted $14 for the line that connects the hand pump to the input for the spin on fuel filter, that was for the tubing with the metal fittings at both ends. The copper seal for the filter end will probably be $2.50 more. Kinda expensive, but whatever. Leaking fuel needs to be fixed.

If you have that number, let me know.

By the way, thanks for the photos and description. It has really helped me with this repair.

thanks

Hi surfblau,

I think the p/n for the line you want is 615-070-42-32 (maybe double check with the Marin dealer). It would be about $6-$7 from Wholesale Parts in GA, and the copper rings (007603-014405) would be about $0.50 each. FastLane or the PartsShop should also be able to get them but the prices don't show in their online catalog. Here's the contact info for the guys in Atlanta, GA:

Wholesale Parts (*************** - website under construction)

Note: S&H is a flat $9 per order, but items that come directly from Mercedes (like these fuel lines) arrive FedEx Express for the same shipping price. Aftermarket items, like fuel filters, will usually ship UPS ground from one of several warehouses. Just FYI...

Have fun!

Did a search, and this is what came up... Will start fresh if needed.

Anyway, tried ordering through my source, two or three N.L.A., and one was $41 and the others $30, if I understood right (his phone system is acting up), for you alls information.

I am not paying $175 for one meter of fuel line with fittings! So, what size is the line? I know it has to be heated to R. and R..

The reason I am seriously considering this is I am tired of a clunking engine, including while driving.

Since I can't fix the link in my previous post, here's the photo.

I'm not sure what part numbers you are looking up, or where you are getting your price quotes, but I'm seeing all three lines at $40 total (plus S&H) from a vendor who is not allowed to be mentioned on this site...two are under $15, one is under $10. Even from Pelican Parts they are $55 total plus S&H ($20, $20, and $15). I can't get $175 out of that unless you're buying them for 3 or 4 cars.

Might want to do some more reserach first, eh? Also would help if you posted the year & model in question. The previous posts in this thread were for the OM60x engine. For the OM617 it's still only $60 for all three plus S&H...

Thank you so very much!

What I need more sleep...

OM617a. There is a reason I have my wagen specified in the signature... Oh well!

The dealer is N.L.A., unless they were being lazy which I VERY much doubt, as found one for $41 and the other lines at $30. so you are right, $130 for all four. I can't find on the Peach, and don't recall on the Hauz or the Source. I have been rudely treated by the Peach, so...

I did find the hose at Greaseworks, just need to order. Plus, looks to be a 300D in a local yard, so maybe get lucky and find the fittings. Then be plug and play. I so want to get her back on the road!
