HI

ANyone know where I can get / what can used for replacement fuel lines ? I know Porscheshop.co.uk offer them, but they are at 200, which is a bit steep for two steel tubes...
Thanks

Hi Ian,

I have had this problem on my 931, the fuel pipes are way too expensive. The low pressure pipe (fuel return) on mine corroded above the rear torsion bar carrier, and about 5 years ago the corroded section was cut out and replaced with a rubber section by Paragon Porsche in Sussex (UK). I haven't had any trouble since then. It cost 45 inc labour.

Recently whilst having other work done by Harvey Motorsport in Essex (UK) they told me that the high pressure pipe has corroded in the same place. They said that there were now special high pressure rubber pipes which could be put in place of the corroded section, and that they use them in their cars without problems (they race 924's after all), they did point out that you had to be careful and use very high pressure pipes though, and be careful how they are joined to the existing pipe. I haven't had the work done yet, but that at least gives you some options.

You could also try http://www.porsch-apart.co.uk as they have a large supply of used parts.

Hope this helps,

Kevin

Thanks for the info.
I agree that the joints are the problem, I was also wondering if copper - nickel pipes could be used as they can be flared easily and are acceptable pressure carriers (used in brakes after all).

Copper pipe/tubing is NOT used in brakes. It can't withstand the high pressure that the brake system has. They should hold up fine for fuel unless there is a chemical compatbilty problem just check the pressure ratings before you buy it to make sure it is rated for the pressure in the fuel system.

Copper tubing can withstand high pressures of braking. It is used in refrigeration with pressures around 500PSI and it holds up fine. The only reason it isn't used in brakes is because of how soft it is . It can't take rubbing up on things much or else it'll break.

Hi All,

I ordered some fuel lines from Automec this morning - total cost 52- compared with 176 at the porscheshop.co.uk.
If they are OK - I'll let the board know.

Previous poster - thanks for the offer of looking at your fuel lines, if the ordered ones are no use, I'll get back to you.

Thanks

ian

HI

Automecs fuel pipes arrived yesterday - out and return, with fittings. Should be a simple matter to bolt them in . Good price and service.

Hi Ian,

Thats very interesting, I didn't know Automec made Fuel lines also. I have a full set of Automec Copper/Nickel brake pipes, they have been excellent and really easy to fit. Automec also custom made a new Hydraulic Clutch hose (931) for me after I sent them the old one as a pattern. They charged 25 (approx) compared to 60 from porscheshop.

Let us know if the Automec Fuel lines are easy to fit. Are they Copper ?
