My clamped U-hose lasted about 5 years and ~10,000 miles before I discovered that I could turn the clamps by hand. No leaks but I wasn't about to wait until it did.

The belt is the same age if that gives you any clue as to what I get to do this weekend.
Nope, using Gregs. There are still a few of those out there that I've not been able to track down so I can change them over. Mine was one of the first ones I saw leaking a few years back, the U and clamps were on there for about 3 years but I checked it every few months. I've seen more of them with cracked outer rubber and that was enough for me to stop. I've cut each one I've replaced open to check to see how the clamps and barbs worked together and it wasn't good news at all. Some were fine, some were bad but you have to cut them off to find out.
Now that I have the SC on there I made up my own contraption.

The cracks on the outside are not relevant to the fitting discussion. That's a completely different subject. You can do the personal attacks all you want too, I'm not going to sink that low. It's a trademark of yours when you run out of ways to discuss a subject. Post up some proof that the replacement house are leaking because of the barb fittings and the clamps on the 928 so it can be documented. I don't have anything against something that can be proven to happen in real life. Theory must support reality.

The makers of the booster rockets for the space shuttle had never had an o-ring failure until a particularly cold Florida morning. Of course, their engineers had warned against firing the rockets at such temperatures, but that was just theory and not based on actual use in the real world.

I'm a little baffled as to why 928 fuel lines are so special when compared to modern type fuel hose used in vehicles that undergo the same thermodynamic conditions as a 20-37 year old car.
This should not be such a debatable topic as it is, whether you are using Greg's fuel lines, or Roger's cut and clamp method (which he no longer sells unless you assume liability). Even then, with clamping your hoses, just checking them should be a non-issue if it takes 10-15 minutes out of your life once every 6 months.

EDIT:
So if I got my EFI hose kit in 2013, what hose did Roger sell me? I keep seeing hose differences of plastic versus rubber. Obviously clamping rubber hose on a sharp barbed lines is a 'no no'.

Coline and the Goodyear (blue internals) are the only ones I've seen with the plastic liner, that green printed hose is the mutlifuel that's good with Ethanol. It's a normal rubber hose.

So I have to change mine then????
And if so, what is the part number of the hose, or model number for the Goodyear?
I thought Gates Barricade is the 'goto' hose for Porsche?

What's with the name calling? Anytime you are backed into a corner, the name calling starts to humiliate the other person. Greg there is not a single documented case of a 928 ever having a leak, let alone a fire from using fuel injection rubber hose with fuel injection clamps. Hundreds of these kids were sold and have been in 928s for about a decade. Some like mine, are used is boosted applications where the fuel pressure isn't around 40psi but around 100psi and yet none failed. Also, it's interesting how you are against the rubber hoses with clamps on barb fittings yet aren't you selling the same thing for the 16V injectors? The injector barbs might be slightly different than the fuel lines but they are still barb fittings.
You are so bad at understanding this, I'm starting to wonder if you and Kibort are the same people.....
Here. I'll highlight the important stuff, for you.....but read everything in blue.
The early fuel injection rails were originally equipped with rubber hose, which has a completely different barb than the fittings originally used for plastic line. The correct replacement rubber hose works perfectly here, as this is what the original design was made for!!!!
The barbs on the fittings made for plastic line are extremely sharp and can cut the inner liner of a rubber hose. This is the application that the makers of rubber hose specifically do not want their hose attached to!!!!
I know this stuff is really tough for you to understand, but try and keep up.

Sean,
The blue internal material you mentioned is Fluoroelastomer. Continental sells a 5/16" hose with this material, but in black. If it meets the J30R9 rating, can I use that instead?
I also saw this one in NAPA. It is the same construction.

Sean, my apologies for hijacking your thread. I will post no longer about clamp on EFI hose. This hose is dedicated to your product, not to anyone else's.
