Oil line threaded fitting broken - where to replace?
 

Sorry, not sure exactly what the thing is called, so I'll post a pic. It's the same fitting on both ends, and I broke BOTH of them, trying to reattach it to the engine block. I wasn't applying much pressure at all, certainly not enough to seal it properly. I've removed and replaced the oil tank end several times, so I have a good idea how much torque I can apply there, but when trying to attach it to the engine block last night, it split. When I tried the other end, it also split. Uggh.

I can get the elbow pipe off the main hose easily enough, and thus slide the threaded part off. Is this a generic fitting that I can replace at several places, or a special order part that has to come from der vaterland? I think I know the answer, but hope springs eternal...

Thanks!

That looks well a truly mangled... What did you use to undo it?

I would buy a brand new replacement but I'm crazy that way.

As an alternative you should be able to find a good second hand one in a breaking yard. If you go this way make sure it's clean in the inside before using... (Apologies in advance for stating the obvious)

Pelican also sell spanners that will make the job of refitting a new one easier.

I'm sure you could make some custom fitting to replace the ends but it's not as easy as it looks (and probably more expensive than buying a new hose).
If long term reliability is important to you then OEM is the best option.

I used a 36mm wrench, like I always do. I was mistaken above - the threaded coupling doesn't need to come off, I need to replace the entire elbow on both ends, but it looks like it should be a fairly standard oil fitting:

That is an original aluminum style swedge type fitting which are no longer available.

I suspect the whole hose is original and should be replaced.

The aluminum style are very prone to cracking since most are 40 years old, they are really best for concours guys.

Buy a new hose which will have the later style steel crimp fittings and you won't have to worry again for a long time.

Is this the proper replacement? (remember, it's a 1972, so specific year is important because of the different oil setup)

For absolute certainty, send a pic of what you want with measurements on it to Pelican and ask. They're happy to help.

If it is only the tube nut that was destroyed, this might work for you

It is designed specifically to replace a tube nut without removing the hose for the hose end.
