I'm going to see if I can do a bundle deal somewhere, possibly including the rail. The testing place want a €115 for the injectors to be overhauled. I'd rather get everything from one place especially as one of the injectors looked like it may be from a Mondeo, it had a different locking sleeve which had a flange on it. For the sake of a couple of quid I think it would be the better option.
I'll look how much the pipework is, otherwise I'll try and clean it the best I can.
