Is it possible to change the front to rear fuel lines....

...without dropping the rear beam?
Mine are seriously rusty right where they go up and over the rear axle. Some of the brake lines up there need replacing too and it looks to be impossible to get the new lines installed in the original locations with the axle in situ.
Is there a trick? Or do I just have to crack on and drop the axle?
Cheers

Yes, you need to drop the rear beam to fit OEM pipes. It's possible to replace with flexi pipes without dropping the rear beam which is what I did. I fitted the braided hose kit from RPM but there are many different DIY routes. Lots of threads on here...

Here's what I did on one of my 924s which are broadly similar. Get two 10 mm compressiom fittings per pipe and a roll of soft copper tubing 10mm od. For example a 20m roll from RS is under £60 Do not be tempted to straighten the coil out before use as it will harden quicker than you think. Feed the tube directly from the roll following the desired path and use the compression fittings to connect up to the cleaned up ends of the good uncorroded pipe; put some loc-tite joint sealant around the olive on the steel pipe as it needs pulling up really tight to seal. With patience you shoud get out on less that £100

10mm pipe will do the feed but you'll need 8mm for the return.

Nice one, I didn't spot that and thanks for the update. I did only do the feed pipe on my 924. That means an extra coil of 8mm pipe.

My S2 has the RPM braided kit; the labour was about the same as fitting OEM hard lines, and the parts were more expensive. Not the most clever "solution" to the high cost of replacing with original! []

I think i will just bite the bullet and drop the rear beam. I would like to replace the goosed fuel and brake lines with OEM ones and if i've got the beam off it gives me a perfect opportunity to refurbish and repaint the beam and get some fresh underseal onto the otherwise inaccessible areas of the shell.
Thanks for the advice guys,

I have just done this job. I looked at pet and noticed that the lines Porsche sell now come in two pieces each . They have a break just before they go round the torsion beam. I made new lines front to back using 8 mm and 10 mm pipe. I used the correct jointing pieces and all the correct fitments. I didn't find it difficult to go round the torsion beam. I flared the pipes on the car it took me an afternoon and cost around £60 all in including the pipes and fittings. Although I also bought new clamps to hold the pipes to the floor from Porsche and they were as much as the fuel lines themselfs.
