After running out of fuel due to the low level light not coming on i decided to investigate the problem. I found the that the previous owner had unplugged the bloody thing and had hidden the connector!! tw@! So once connected the light was constantly on even though the tank was full. Do i need a whole new unit including level switch or just the sender?
I can't remember off the top of my head but
I'm sure there is a test proceedure for the sender unit on the good old hayne book of lies.
Give a shout if you need it and I'll go have a look.
