Gooday, Are there any updates on the fuel transfer light staying on? I have read the archives and tried the suggestions but still cannot fix the problem. At first I thought the pump may gave been wet considering the flood waters we had to go through in Bundy, but pump and connectors are dry.
Cheers,

Try and disconnet your positive battery terminal and wait a few seconds and reconnent it and the light should go away my 2001 gu does this regularly if this fails try the negative terminal as well. Good luck.

Oh! Oh! I spoke too soon. Every time I put fuel in the main tank this flippen light comes back on. I have to take off the Battery Leads to stop it.
We have Auto Electricians out there , is it a faulty switch?

If it only happens after refuelling the main then I would suspect the Sub Tank computer or possibly the main tank sender.
Every time you turn the ign on the transfer computer does a self test under certain conditions and pumps fuel for about 15 seconds (fuel in the sub, main tank below a set level etc). If it passes this test then it won't illuminate the warning light.

If it fails and illuminates the warning light (not the transfer light in the switch) then it is sensing something is wrong. You could possibly try adding earth straps at the tanks.

I am also assuming from your posts that when the main is, say, about 1/2 way and there is fuel in the sub and the warning light is off or reset then the sub pump will actually transfer fuel or at least self test?
