MG MGB Technical - Petrol leak

Recently noticed what I thought at the time was engine fumes maybe from the breather system but could see no problem. I turned the ignition on to get the fuel pump clicking to see if maybe the float chamber overflow was showing anything but it wasnt. I then noticed fluid dripping from further back. It turned out it was leaking petrol from the T connector to the carbs. Just a loose connection but dripping on or very close to the manifold obviously potentially very dangerous. I did remove about a year ago a faulty filter and probably never tightened up the hose enough so I have learned I must be more careful. Just a word of warning.

Trevor,
good point.

Did you slightly slacken off the jubilee clips before tightening them otherwise they can feel tight but actually deform.

I've just very recently completely moved away from using those very small jubilee clips and instead use pipe clips that only cover a 2mm range, similar to those you have in your photo float bowl overflow connection.

Spring clips are better than either - https://hcl-clamping.co.uk/products/spring-hose-clamp-light-rotor-16-4-21-0mm-zinc-plated?variant=31814448054349&utm_medium=cpc&utm_source=google&utm_campaign=Google%20Shopping&gclid=Cj0KCQjw4f35BRDBARIsAPePBHyQtSjI5jHmNQCfGS_vo5_XAK674vA6ADtjdlqYFc7wsI1RJq39ckkaApjcEALw_wcB

There should be a heat shield in front of the heater box and the solid pipe should be fixed to that with the pipe running between the shield and the heater box.
