Fuel Leak Underside Rear Of Car
Posted 19 July 2012 - 07:08 PM
I had just finished fixing my wind-up window and needless to say the car couldn't leave it five minutes without something else going wrong. I smelt fuel, looked underneath the car and noticed fuel dripping where these two hoses dangling beneath the boot join - see photos.
Can anyone suggest any quick and long-term fixes please?! This a common thing?

Has anyone had a drip here before? Can I cut the ends of the existing pipes and renew the clips or will I need to renew one/both of the rubber fuel pipes as well?

Anyway, when it comes to replacing them I'm confused.. why is there a joint here? It's basically one length of rubber hose which comes from the tank, to another length of hose which curls round the subframe to the rear floorpan and connects to the copper line. Should it be just one stretch or is it separate for a reason?
Plus if I am forced to buy replacement hose from Halfrauds for conveniences-sake do I need 6mm, is that the same as 1/4"?

Your main fuel line ideally should not be copper. It is not as unsafe as copper brake pipe, which fails when you least expect it due to fatigue arising from pressure cycles, as the fuel system pressure is negligible, but it still does tend to become brittle due to low level cyclical stresses due to vibration. And. it reacts with certain fuels. If I recall correctly, those containing alcohol are the main problem, and may result in carburettor contamination. But worry about that the next time you do a major strip-down, it will be ok for a while.
If you check the Somerford Mini web site, you should find pictures of the various fuel lines in the parts catalogue, which will help to show how the lines should be run and joined.

Anyway, I'm going to replace both rubber sections of hose going from the tank to just past the subframe with one section to eliminate any weak points. I'm assuming this is how it was in the first place.
Should I get rubber hose and a couple of new clips or is there a stronger option e.g. I've seen braided online.
