I currently have my saxo VTS on the ramps and one of the two pipes coming from the rear of the fuel tank has been worn through by the handbrake cable and something is leaking out of it. Does anyone know what these pipes are for and what they are like to replace. Also is this leak likely to be causing my car to be stalling and hesitating as posted earlier?
Thanks
I did a similar repair to a Toyota Supra. I used 1/4 inch fuel hose. Cut the pipe and pushed the pipe onto the ends then used jubilee clips to secure, worked fine.
If the car isn't getting sufficient fuel pressure this is probably causing your problem.
The two pipes dont actually go into the rear of the petrol tank they both go into a small white plastic device thats mounted on the flat part of the tank.
TBH, on the whole, _any_ pipe leaking something at this end of the car is going to be bad news.
Smell & feel the stuff coming out of the pipe.
If it's thick & oily, it's brake fluid.
If it's thin & petroly, it's petrol.
Given they're going to the fuel tank, it will either be the fuel feed or the fuel return (do they still use fuel returns?).
Given it's a VTS, it'll have fuel injection. These systems can get up to quite a pressure, so the pipe will need replacing carefully. Either the whole length, or just the worn section, using a piece of equivalent bore pipe, some brass pipe (to jam into the new bit of pipe, and the old bits, and some jubilee clips to hold it all in place.

If I read you right, there isnt actually fuel pressure in these pipes...? They are inwhich case those for the evapourative emission controls which routes fuel vapour from the tank to a charcoal canister which are then drawn into the engine and burnt upon control from the ECU. If you have a sufficient enough air leak then yes, it would cause poor low speed running / stalling etc.
Tim..
Yeah the fuel pump with feed/return pipes is mounted into the top of the fuel tank(under the rear seat). Im considering, as pete said putting some metal tubing in place of the damadged part and using jubilee clips to secure it.
If you are sure these pipes are coming from your fuel tank and they are leaking you need to get them fixed. Does the leak smell like gasoline (open the filler cap if you need to compare)?
If you can see the end fittings they shouldn't be too difficult to replace but also it wouldn't be too expensive to get it done professionally. You will need to buy fuel quality pipe of the correct diameter and the correct end fittings.
Finally, this leak is most definitely not connected with your engine running problems. This is more likely to be related to the idle control system.
I can only see one end of the pipe(connects onto the white device mention earlier) the rest of it dissapears behind the fuel tank
