W108 M130 - Engine bay Fuel lines?

[Bdub03]

I'd like to replace all of the engine bay rubber fuel lines in my 280se M130 MFI but cannot seem to find them anywhere aftermarket. Has anyone had luck with this or have made new lines themselves? The old appear to be crimped to a banjo fitting. Also assuming I'll need new crush washers.

Thanks

You might be best off hacking the old stuff off instead of looking for direct replacement. I used 5/16 (8mm) fuel line with hose clamps.


Oh wait...you're fuel injected right... That might not work

Just start with contacting industrial supply houses that make hydraulic hoses. You may have to talk to a few of them to finally find the right one but these hoses are nothing more than a gas hose with the correct fitting swedged into the end of them.

I usually just contact a farm supply house that makes hydraulic hoses for tractors and if they can't make them they can usually direct you to someone who can.

Just take in your old hoses and ask if they can make them.

I recently picked up a crimp tool for AC lines so I may give it a shot, or convert to AN if the fittings are similar.

Was only curious as it's a mess down there and I'd hate to have an engine fire. I'll post pics during my progress if anyone is interested.

I have to replace mine so I'm DEFINITELY interested in seeing progress pics!

That and then my fuel injector cleaning process. I'm following what the Porsche guys do using an ultrasonic cleaner. Very excited to see how this turns out.

I recently cleaned some injectors from a 1970 280SE. I use a professional ultrasonic cleaner much like professional labs use and left them in there with some Berryman Chemstrip (I think that is what it is called) for about 24 hours. It didn't do a whole lot.

I then used Berryman carb cleaner to hose them down and scrubbed them off with a brass brush, a small one, to get the outside crud off. Then I ultrasoniced them again and the results were pretty good. You could see the little screen inside of them and they were spotless. They also had a much better spray pattern.

I guess the poor results the first time came from expecting the ultrasonic to do the heavy cleaning as well as the fine. So before you drop them in the US tank give them a good old fashioned scrubbing in the parts cleaning tank.

Idle - Much appreciated. And yes that would make sense. I plan on giving them a nice external cleaning before I drop them in a bath. Here are what the porsche guys have recommended.

155f bath w/ a mix of 1/2 turpentine + 1/4paint remover + 1/4 acetone for 24h. Rotating every 4.

That sounds like a much stronger formula than I was using but I don't see any reason why it would not work or would be unsafe to use.

Thanks for sharing this since I doubt that the batch of injectors I cleaned will ever be the last time I do such a thing.

I'll post results once I complete the process. My M130 runs pretty rough with a solid spark and decent compression across the board. Last thing is fuel...

So I finally got them in and have to say they look great!

I ended up doing all 4 lines under the hood to eliminate any risk of future leaks. Used high pressure R9 fuel injection hose.
