getting vacuum hose onto banjo fittings
 

The oil line for the ip, part #6171800127 is NLA.


Instead, MB sells 2 banjo fittings and 1 meter of vacuum hose. To be assembled and used instead of the pre-made oil line.


So, measuring the existing line and cutting the exact length of hose is not a problem.


But I imagine getting the hose onto the barbs of the banjo fitting is going to be challenging.


So what's the best way to do this? heat the hose ends in boiling water?


or is there a better way?


thanks for reading!

I usually heat hose ends as well if they are very hard to slide on. At the same time use some judgement. You do not want them so soft they create other problems sliding them on.

whats your preferred heat method?

that sounds like making hard nylon fuel line repair of modern cars, The way I do it is to heat the line in boiling water and immediately push on the barb. You can also form the line into shape if you are feeling crafty.

I have done this a few times on fuel injection fuel hoses. Same principle.

You can also use a heat gun, but I think water is more safe as it wont melt the plastic

I bought the same thing. There is 2 ways I tried that worked.
Also it is not vacuum tubing.

See the pics
On way I cut a section of rubber hose and slide it over the Plastic Tube and I taped the Jaws of a vice Grips so it would not scar up the Banjo. And I used a smaller vice grips to grip on the rubber hose and tubing and shoved the Banjo fitting into the tubing.

On the other end I did the same with the banjo, tapes and vice grips but used a glove with non-slip ridges to grip onto the tubing. The 2nd pic shows the glove.

I cannot remember which worked better but both did the job.

Agreed... it is fuel line, not vacuum line. And yeah, dipping JUST the part to cover the nipple into boiling water, the slipping it over is the easiest.

Fit the banjo conector on the pipe first .Use the warm water idea . Then if you dont get it right the first time you will have enough spare pipe to work on [ Dont cut it to length first]

Jabstic420 indicated "To be assembled and used instead of the pre-made oil line."

So it is not a fuel line. It is the line that supples the Oil from the Engine block to the Fuel Injection Pump. In the pic it is hard to see the green arrows that point to the oil Supply Line.

On my own Car I got 97 psi max Oil pressure when I revved the Engine. That means the line has to take that pressure.

Since the Oil gets a hotter then boiling water I doubt if that would hurt it during assembly but the other ideas of heating up the plastic could be bad and allow it to slip off at a later date due to the 97 psi.

If a Fuel Line slips off no damage is going to result but if the Oil Line slips off there is a chance of running the Engine out of oil if you don't notice it is leaking.

It looks like the banjo bolts are on parallel axes. Is there any clocking involved?
