I've noticed that the sender unit is attached the fuel pump and therefore not a cheap piece of kit to replace. I have the error shown in the hand book i.e. the fuel bars lighthing up from both ends and flashing to the middle. Sometimes it sorts it self out. However with this I am now getting false readings. The first bar used to go at 55 miles it now does it at 35 and so on. Can anyone give me advice on this. Is it fuel sender/pump or control unit, which is I belive intergrated with the clocks? Thanks M.C.
