Replacing 928 Fuel Lines - a guide
Most of you know that the engine rubber fuel lines are often NLA (no longer available) from Porsche. And that your engine fuel lines are old, cracked, and brittle due to their age and the harsh environment they live in.
Fortunately, they are not hard to service.
We have been selling the correct metric high pressure fuel lines for a number of years that allows you to replace yours... one meter of it is only $15 and that's enough to do all the above-your-engine fuel lines and still have some left over. Here is a link:

To make it even easier for the do-it-yourself-er, I have sourced the correct Oetiker clamps and the crimping tool that you need. The tool and 25 clamps are less than $28. Here is a link:

Together - they cost way less than a replacement hose from Porsche (if you can find it) and certainly less than you'll spend after an engine fire.
The clamps meet SAE spec J1508 and fuel lines serviced in this way meet aircraft A&P maintenance certifications. This is a good repair.
Now - HOW TO DO IT:

By rebuilding the fuel line from your car, not only will you save money compared to buying new, but you are also assured that it will have the correct connections to match your car.

Looks like what we have "all" been doing for the last 10 years - cue Greg in 1,2,3
Seriously does not look like the same hose Porsche uses. Does your hose have the correct polyamide veneer for use with barbed fittings?
