petrol leak

[Guest]

I have a bit of a petrol leak going on[]. I want to fix it as I can't stand the thought of paying the government ludicrous tax on fuel when I fill up only to watch it drip out again[]

The leak is coming from the front, approximately in the centre of the car. It is not gushing out at the moment, just a small leak at the moment but I need to fix it before it gets worse.

Question is, what is involved in changing the fuel line? How much is rubber after it comes out of the tank before it becomes a metal line through the car? What sort of time is involved as this is something I am short of?

Any help appreciated.

dead easy


It is the pipe from the (what I call the ) finger filter (which is the brass bit in the fuel tank) The flexi fuel pipe is then about 20cms long this then goes on the metal pipe which goes to the back of the tank.

Now to replace here goes

Disconect battery as they all say...

Use up as much fuel as you can and then undo the big drain plug. Remove contents in to a bowl

Under the car you will see the flexi fuel pipe.

At the tank end remove the pipe clamps and then remove the pipe.

Do the same the other end and remove.

Tip ...

as you are removing it any way just cut it and then remove the small bit left easy then might have to cut it with a knife do this at an angle from front to back

If you have trouble getting the new bit on here is another tip as this fooled me.

I found that no matter how much I got the pipe warm with hot water by the time I got to the finger filter it had cooled and I could not get it on ( oh er misses ) to I needed to open up the pipe abit.

So get hot water and a knife sharpener (steel) I think they are called when the pipe is warm push the steel up the pipe thus stretching the pipe blow on it to cool it so hopefully it holds the shape of the steel then warm it again and push on to the fuel finger . the other end was ok for me but if it is not repeat the above. Now I also put on one clamp on the finger filter end and two on the other..

have fun so many people do not replace this bit ,it costs about £3 and can if not replaced have a horrid effect on your car if it all goes pete tong.....

Now if it is not the pipe and it's old any way replace it . It can be the gasket from one of the plugs or the fuel finger either way I ordered new ones from Porsche and they were just copper gaskets . Next on the list is a split tank but I doubt it.

Best bet the pipe...30 years old.....

Oh and jack the car up when you do it and use all the correct stands etc....blarr blarr blarr.

Thanks for the tips. Can you remember if the hose is 5mm or 7mm internal diameter?

te he. I think my pipe was a Friday pipe grrr, but at least it's not going to leak it's on tight....

I can't remember to be sure. But it was the same as the pipe that runs out in to the engine bay on the left so get a size from that.

No problem. I'll do that. Makes sense really!
