Hi everybody. I am Pablo from Spain. I own a XJ12 5.3 form 1988. I am fixing the car, it had quite a lot of problems, some of them electrical, I have been using wiring diagrams from an XJS V12 and they worked fine until now. I have a problem with one of the fuel senders and all the information I have is for cars with just one tank. I can’t find anything on internet. Does somebody have wiring diagrams for the fuel senders and fuel changeover valves of this car?
Thanks a lot.
 
pablo,
best i can offer for now (as there's very little info on the fuel system) sender units usually are light green with orange stripe, fuel pump> brown with slate stripe, changeover switch usually has the same colours.
