DOHDOHDOH!!
Just rememebred I have a set of Fuel lines in my shed!
Now then, I assume that the connector to the injector is the same size as the one for feed to the WUR (on the metering head). CAn anyone confirm this? Looks identical!

Also can anyone tel me how I get the banto bolt bit out of the end of the flexible pipe with cutting it? I don't wan't to destroy it as it is a good spare and they are £40 from VW!!!
Cheers
