Had another bad fuel leak develop on the engine - the vibrations seem to have work hardened then split one of the original nylon pipes.
I've now replaced it with decent fuel grade rubber flexi-hose, but not before losing quite a bit of diesel, hence the current overall MPG figure being pretty abysmal.
I *think* its not got any leaks now, so hopefully the next lot of figures should improve matters (yes, I know, eternal optimist n'that...)
