I have attached the new after market fuel pump. I have a strong suspicion that is much more effect and as a result it is causing a leak in Carburettor.
It started first time after fitting the new pump but unfortunately it is running very rich and after running for while it runs quite badly and idles very slowly.
Here you can see that the IN and the RETURN feed on the Carburettor.
The Leaky Carburettor, probably from two much fuel pressure from the new fuel pump.
Here you can see the IN and RETURN from the fuel tank into the engine bay. I dont know what the top line is but second and third down is IN and RETURN.
