This is my cross over fuel line underneath the oil filler. It has significant failure of the outer sheath. I have not removed any more of the pieces and parts that are covering the other hoses beneath the air cleaner so do not know their condition.
Is there a reason not to use hose clamps on this line or better question would be should the other fuel lines be crimped at the barbs like this line is when replaced?

 

Aside from the bulging, the line looks quite old. This line goes in the trash. If you do not know the condition of the other lines, I'll wager they are the same age.
YOU REALLY NEED TO EXAMINE EVERY OTHER FUEL LINE UNDER THE HOOD.
Call Roger and replace with Greg Brown's fuel lines.
They are teflon and then braided. They are of the highest quality.

Add: Here are some pics of Greg's hoses.

 

Because the clamps tend to make the barbs cut the liner of the hose. Get new hoses or those re-lined professionally.

 

NEVER use hose clamps over a barbed fitting and to not even attempt to start the car until ALL the flexible fuel line have been replaced - unless you plan on hosting a barbeque....

Use the search function. Lots of threads on fuel lines.

 

Greg Brown makes some good looking fuel lines...

Yes! Car is Red X'ed until I get new fuel lines. I saw the bulging tonight when i was rooting out my engine serial number. This is a new car to me and the more I dig, the more I find.

Is there a Vacuum Line Kit like this for the car as well with all the plastic elbows and tee's?

Wow, never seen a berry aneurysm in a fuel line, be glad your 928 didn't suffer a flaming hemorrhagic stroke.

I'm sure that Tom or Roger can put together a vacuum line care package for your vehicle.

 

Tom,
Greg designed, chose the materials, and produces these. The fittings are made in Germany and are quality metric pieces. They are a little pricey, but you will have piece of mind regarding the fuel lines you can't readily see.
For vacuum 'kits', call Roger. If he doesn't have a 'kit', he'll compose one for you.

 

Excellent pickup on the berry.
The internal line (the intima) is obviously damaged.
Rob is right. You were close to a rupture.
You are fortunate !

 

Very nice indeed but, dare I ask? $1500 for what you pictured? I assume the picture to be all required for 86.5?

Auto parts store fuel line, and the right type of hose clamps works just fine. This is what everyone was doing 4-5 years ago. Just make sure the fuel line has the proper pressure rating, 125psi I think, and get the right type of clamps.

 

Can't beat those made by GB, Porsche would probably use those on the 928 if it was built today. One day I'll replace mine again & those are what I'd go with. Not inexpensive, but very cost effective!

 

Denny,
Yes they are pricey, but one doesn't need to purchase them all. I purchased two for the 'not readily seen' lines below the air box - FPR to dampener and FPR to cooler. The line for the front dampener to rail I left with the OEM for I can readily inspect, so I didn't have to go 'whole hog' for Greg's lines.

As to if the pic shows lines for an 86.5, I'm not sure. I found it in Search and just wanted to show the OP what they looked like.

 

The above statement is totally incorrect. All the hoses on the 928 are rubber/polyamide over a barbed fitting. They are "push fit" only and use a collar to hold the hose in place. SAE30R9 was being used in our hose kits and there was a theory among some that the barbs cut into the inner rubber wall of the hose which could lead to a potential leak. In practice this was not the case as proven by thousands of users. In reality, should the hose be changed after a few years to be safe - yes. Should the clamps and the hose be checked every year - yes. We moved to the Gates Barricade hose about 12 months ago as it has much better compatibility with the nasty crap they put in hoses today. Both types of hoses have working, proof and burst pressure ratings WAY above what the 50psi or 70psi systems on our cars use.

I sell Greg's hoses because they are simply the best. But not everyone can afford the cost.

I am just completing some new sets of hoses that use the original Cohline hose with the polyamide liner EXACTLY as supplied from the factory by Porsche. These will come with the collar as well. I would prefer that customers use an EFI hose clamp instead of the collar as it is another level of redundancy. We already have some sets with customers awaiting feed back.

 

Roger,

Excellent post, thanks. I wasn't sure if you were still selling the basic fuel line kit or not.

By "nasty crap they put in hoses", you mean alcohol in the gas? It definitely makes sense to find the latest hoses designed to handle today's additives which are different from years ago.

 

If it was today Porsche would probably use nylon only for the fuel lines, heat shrunk (looks heat shrunk to me) to the fittings, just like almost all the cars today. Very robust and long lasting setup.
