[928uk] fuel lines

[Richard Armstrong]

Groan
Just got the car running like a good 'un and......
bloody fuel leak. One of the fuel lines running the length of the car, 
leaks just behind the drivers door. Badly.
It all looks a bit corroded, so I suspect just changing a bit of it will 
not be sufficient.
Has anybody replaced the whole line, and how much work is involved. 
Usually the fuel lines are the first in at manufacture.
Not having much luck right now

I also have the door lock blues, with a slight difference - not only do 
the locks pop back up when locking, they lock themselves occasionally 
too!
I suspected the immobiliser fob, but when the door have locked on their 
own the immob' is not set.
I do not leave the keys in the ignition!
