Technical Petrol Part Request

[Essiv]

Hello Guys,

Actually I'm wondering about this part of my fuel system. I'm also owner of a Opel GT 1970 but the fiat spider is overall different.

So as you can see a part of the fuel hose broke already because the rubber was already hard. I just wanted to replace it, but there is this metal part at the end, which I have never seen before. It looks like a cuff, but I'm wondering if it's also fixing the fuel hose.
Finally I tried many times to get rid of this broken part hose, but it's fixed/stucked in this place. How can I get it off?

I always liked the Opel GT, it just looked right.
There are others on Forum who have greater 124 Spider knowledge than me, but I don't recognise that part, is it something for emission regulations recycling exhaust fumes etc.?
Or some kind of water heating device for the coolant.
Regarding the cup shape below the remains of the hose, to me that looks to be part of the lower section and not meant to detach.
Can you see if it's any clearer after the rest of the damage hose is removed?

I trust this is a fuel injected 80s 124?

It looks like the fuel pipe from the fuel rail to the cold start injector. This is a pipe with a ferrule that is crimped originally…your left with a piece of the ferrule. I used electricians side cutters to nibble away at the ferrule, or you could be gentle with a Dremel with a cutting disc. Once removed your left with a barbed spigot, just replace with a new piece of pipe and jubilee clip.

Hello everyone,
thanks for helping me in this case.
So @gengis yes i think so, must me crimped because its hard to get rid off. Yesterday i tried with a cutter an screwdriver.. but no chance.
@bugsymike this is the "last" part of the fuel-injection system. I attach the detail and marked the refering spot

Thanks, that makes it much clearer.
From the photo for some reason I thought it was a much bigger part.
So if on fuel rail side the fitting hose and clip will have to be good for over 60 psi?

Yeah must be like up to 5 bar pressure.
But I got no idea how to unplug this hose part which is still stuck on the pin port of the injection. And for me it's completely unclear what this disc/plate looking cuff is about, which is mountet between the plug and the hose

I mean on Opel GT I just mountet new fuel system and the whole system is secured by typical cuffs which squeeze it by screwing.
But this thing here seems more like a "stopper" for the hose

 

[bugsymike]

Can you obtain a correct new hose with the fitting?
I assume it is a push on and lock type arrangement, in which case that "ferrale or stopper " on the end must presumable be able to revolve if not rusted, in which case is there any release mecahnism below the ferrule to allow removal.
Possible @124BC1 will be able to advise.

Hmm I tried already to pull on that metal "ring" but the hose stops it I think. The ring itself is moveable. It's easy to turn in every direction. This also makes no sense to me because: why can I just move this ring left or right around easy while the hose it stuck as f*** in this thing

No release clip ring below the thing? Some form of "quick release" or not in your case.

I try again later and upload a video for you guys. So you can see the mess

So here it is. I had to upload it on my Nas:

Just saw your video,
I see the metal pipe has ridges, could it just be a push on fitting, but the rubber remains are jamming the metal ring from coming off stuck to the metal tube?
I would try and cut the remains of the rubber off with a scalpel.

Okay guys I'm going to war on that thing now !

 

[gengis]

Essiv…You are left with the soft metal crimping ferrule, which needs to come off. It will come off with a bit of perseverance and leave you with a clean fuel rail pipe to connect a new rubber pipe.

I see that the pipe/clip to the first injector has been changed, so it would be worthwhile taking the complete fuel rail off and replacing the short rubber pipes and clips with new, as they would be the same vintage as the perished cold start injector pipe. I replaced mine 24 years ago and have been reliable ever since. Jubilee type clips will be fine in this application, as the pipes that are fitted onto the pump and filter are jubilee type clips and hold the fuel pressure without a problem.

 

[Essiv]

Thank you Gengis for your advice. I appreciate that. So which tool would you prefer to use here to get this off. I already tried some but I don't wanna be like cruel to the system. I worry about damaging the system around

 

[gengis]

I use side cutters... see attached photos for reference, you'll see the four injectors and the cold start injector uppermost, the one your having the problem with. hope that helps. As you can see I've just cut the ferrule off and split the pipe for reference.

Thanks a lot for that. I will try this the upcoming weekend

Hello Guys,
I got it
So... The hose was like glued together over time and that's the reason why I didn't get off.
Finally I fixed it. Thanks guys for your help.
