Can anyone help, please! I’ve got a mysterious fuel leak on one of my Webber 34 ICTs. They were new about 14 months (1500 miles) ago. When I arrived at the camp site this Friday I could smell fuel. When I checked in the engine bay I found the small rubber cap from the brass vacuum pipe on the right-hand carb had come off and a small amount of fuel was seeping from the brass vacuum pipe. I retrieved the rubber cap and found it to be perished and split, possibly caused by petrol saturation?
As a temporary repair, and to get us home, I managed to blank off the brass vacuum pipe with some tubing, insulation tape and a jubilee clip purchased from a local hardware shop, but it was very damp with fuel around these temporary joints when I got home! So, what’s the likely cause? Could it be a flooding problem? Any help very gratefully received - thanks
PS: may be a red-herring and not connected but the only change I’ve made recently is to change my single pack exhaust for Vintage speed one so I could fit a standard tow-bar.
