Has any person experienced failure of the fuel transfer pump from sub tank to main tank on their GU Patrol cab chasis. A Member of my 4wd club has experienced three failures to date. Their model is a series 2 dx 2000 cab chasis. Nisson seem unable to find the problem so, HELP.

Roger and the rest of the people who replied,
The transfer pump in the GU patrol is a very simple electric pump which is connected to both tanks via a full/empty sensor on both tanks.
The problem arises because this pump is mounted on rubber, as such it needs an earth wire to the chassis. This wire is supposed to be just for the pump, however if the main earth cable (battery to body and to the chassis) is not making good contact and you add electric devices such as a winch, then the winch uses the small pump's earth and vice versa.
The solution is to make sure that all earth wires are in good condition and making good contact and are of enough capacity.

Thanks to all those that have replied.
I will inform the club member of your comments.
Your replies probably have helped other GU owners also.

And finally.
After a bit of badgering Nissan Aust yesterday admitted to me that there 'may' be a problem with the fuel transfer pump. Nissan Japan are currently doing the mirror trick, Nissan Aust do not accept the earth fault that has been described on this
forum and others. they tell me that there have been pumps returned to Japan for investigation.
If and when I find anything more I will post it to this
forum.
Happy 4 wheeling.
John

Thankyou again for your replies. The problem for the GU Patrol seems to be in the earthing system.The member has fitted additional earths from chasis rail to body and from body to battery earth terminal, this seems to have fixed the problem. Apparently we seem to overload the earth system when we add more electric assessories.
