Fuel Leak

Another nice day today so made the most of it.    First I took her outside and ran the engine up to temperature to check if there were any coolant leaks under pressure.   Initially it looked OK, but then I saw a very small drip.  Confusingly it was nowhere near any of the cooling pipes, and a quick taste test showed it was petrol.  It turned out to be a leak where the fuel line goes into the pressure regulator.

Amazingly the jubilee clip was actually loose and took about 6 turns to tighten up.    I have absolutely no idea how long that leak has been there, but it could have been months as I very rarely run the engine with the bonnet off.    


So a very useful exercise. and when I checked later when the engine had cooled down the coolant was at the same level in the expansion tank.    Good news.    I will still need to do some more runs to confirm it, before I go on the 100 mile+ Stilton Cheese run in April, but there is plenty of time.
