A leak has started under my 205D. I had a brief crawl under in the pouring rain, and it looks like it is coming from one of the fuel pipes which are clipped under the car body, just at the joint between the metal pipe and a rubber pipe which comes down from the engine. If it turns out to be the fuel return pipe, and I separate it to repair it, how much fuel leakage can I expect? What I mean is, is the fuel under pressure and will it piss out everywhere until the tank is empty? Any recommended repair methods? Cheers !

Very common!, 2 ways to repair
1, go to dealer buy pipes and replace! 2, cut leaking (corroded) section, find piece of sutable fuel hose and a couple of jubilee clips and replace! tempory repair will last for thousands of miles!! (did it as a 'get you home' job and ... well... as it worked ..it lasted till the car was scapped!!The return pipe will have a small amount of fuel in it but not under pressure, so a small amount will come out. The feed pipe on the other hand if the tank has much fuel in it, will act as a syphon and try and drain the tank, so be ready with a container
IIRC the return is the thinner of the two pipes.

I'm of the #2 school of thought :) It looks like the thicker pipe has gone. Had a look in Haynes which was up to it's usual standard of not even mentioning how the fuel travels the length of the car. Looks like I'm going to have to get wet and cold. BTW, the tank is now less than a 1/4 full, and the leak has diminished greatly from a drip to a seep. I may be lucky yet.
If you undo the filler cap and blow back up the pipe it breaks the syphon so you dont need to drain the tank.
Why not replace the whole metal section of the pipe with 10mm copper microbore central heting pipe, only a few quid a roll.

Thanks for the tips. I had wondered about copper pipe, but wasn't sure what diameter to use. Thanks again.
I visited my local plumbing place, he said he only sold copper pipe in 25 metre lengths. When I laughed and said all I wanted was about six feet, he snipped off six feet and said just take it, no charge. Result !!! All I have to do now is bend it to fit the clips. Only problem bit will be where it goes half way up the firewall. Wish I had a lift !

That would probably have been the thick end of a tenner at B&Q...

You're not far off there Adrian. I did pop into B&Q on the way. The price was £13.99 for the smallest roll of 10mm copper pipe. I think it was 5 metres, but the price put me off regardless of the length. The packet looked awfully small for £13.99. Bonus was I set off the alarms when I walked out. Probably the "he didn't buy anything" alarm. I never stopped walking anyway, cos it happens a lot to me in shops. It's either the swipe card to get into work or the metal work in my left arm that does it.
And when you want to buy a shower, or a new bathroom suite, or a boiler, where will you go first?
Good business sense by the plumbing place.

Funnily enough, one of the valves on the bathroom towel rail has started to drip. Three guesses who gets my business. I have used them before and they are a lot cheaper than the likes of B&Q.
BTW, I replaced the whole fuel pipe with the copper one. Works a treat. Tickover feels stronger too. I wonder if air was getting in? Big UP to Steve for the suggestion.
