Fuel pipe replacement

[robdimond]

Admittedly, I would do it with Porsche parts if I had to do it again (in the comfort of my garage).
But IMHO there is a world of difference between joining the pipes under the car with fuel line (or worse, jubilee!) clips and running completely new braided hoses from the fuel filter all the way to the fuel rail.
If the torsion bar is being dropped, it would be crazy not to replace the brake lines as well, while they are in there. If the fuel lines are rotted then the steel brake lines are not far behind.

You can also replace the lines with flexible hose which doesn't require dropping the suspension at all.

If originallity isn't important then simply splice in a piece of flexible hose and jubilee clips . it will get the job done for a few pounds . Or better still buy a brake and fuel line pipe kit and make up a short length of copper pipe with connectors and cut your fuel line either side of the rear axle and fit connectors to the cut ends then simply reroute and fix your fuel line somewhere safe and convenient below the suspension.
My local indie did mine for 1x hours labour with parts...well under £100.

I had my Lux repaired by a local garage, no issues at all with the leaking part patched.

The S2 has the RPM braided stainless kit. I would go that way again, but not spend £300-plus on their kit necessarily. I certainly wouldn't pay the 5 hours labour they charged to fit their own kit!

Either way, I don't see how original is any better than flexi options myself.

Tom, if they'd be of any use to you, I still have the fuel lines taken off my 92 built 968 cab last August, which at a guess are very similar to your 91 S2. to me they look in good nick. I'm 10 miles from J9 M20.

Had my complete chassis mounted system changed for nylon (same material as your fuel tank) in 1998. Its never been a problem since.

Now this is a good shout, if you can find the correct fittings to do it and work out a sensible way for the flexible link from the inner wing to the fuel rail (above the fuel rail). A decent, well assembled plastic set on lines should outlive the car! i did briefly look in to this, but my local hydraulic companies generally don't want to know when it comes to automotive stuff...
