Ryan,
Where are you "trick and Treating"?

interesting,
based on what you have there i would have to agree that a clamp will do just fine.
Thats good cause i had budgeted $100-$200 to have the fuel lines redone, but i can get it replaced for about $30 now it seems.
I have to agree with you that the factory fitting looks pretty damn basic.
Thanks for tearing into one, looks like a pretty simple thing to fix

The collar is purely cosmetic and made of very thin gauge metal. It is in no way an integral part of the hose end fitting and does not swage the hose on to the barbed fitting.
Infact if you go and check your hoses you will find that the collar spins freely on the hose end.
Same on a new one.
So the Porsche factory hose has a push fit barbed connector just like the Jag V12 I mentioned earlier in the thread.
This would make the EFI hose with the EFI clamp a far more superior solution to those of us paranoid about toasted 928's.
I am going to look further into getting the correct EFI hose with a S/S braided layer to help against rubbing. I will follow up when I have more info.

Roger that is real interesting looking fitting you have there. The hose repair kit we have here at work has the same style barbed fitting and ferrul. In the kit are some blank ferruls and a clamp that crips them on, maybe they are close enough in size to rebuild them with some new hose!
and thanks for taking one apart.

Ryan.........I have an email into Carl at Motorsports for a 'set' of engine fuel lines replacements w/s.steel braided lines. If the price is right perhaps he'll offer them for sale through his business.

thanks for the offer, but
1) i hate braided lines, i think it looks like crap, i love the new stuff they market with braided line, but nylon not steel and its black, looks pretty sharp when you add the nickel and black AN fitings on the ends as well
2) i think i saw a price of $1600 from carls website for fuel lines for OB cars with CIS and thought that was insane. I cant imagine what it would be for the 3-4 fuel lines on the S4 and later cars.

agree on your 2nd point, actually just over $1000.
I'm hoping that his costs of the 4 replacements for newer cars are comparable to OEM................failing that its EFI line and clamps.

That sounds typical of an aircraft design - a redundant hose - one fails you always have the other.
Looking at the hose I just pulled apart it is a hose within a hose - perhaps a typical design for all EFI fuel hoses.
