I'll try and have a look underneath tomorrow but unfortunately it won't be in daylight due to work
If it isnt something simple like a leaking pipe which do you need to connect to bypass the whole operation and send the fuel back to the tank?
Even if i am unable to get under it this week at least i can help the garage with the info as i am aware the radiator appears to be no longer available so if that has gone i wont have much other choice but to bypass.
