Sub Tank not working
GU 42, 05 model, just knocked the NATS off the back of the fuel pump, and now I have no Sub tank. The pump worked fine pre NATS issue, but it wouldn't transfer during the NATS problem ie; while the security dash light was on in a solid state. I disconnected the battery to see if that would reset it.
Im considering an auto Elec to do a bipass, but does anyone know an easier fix.
Regards Mick.

The only good thing about an 80 series is..... the front end?? Wrong!!, the Engine?? Wrong!! the Full Time 4WD system?? Wrong!! Its the NissanPatrol.com.au stubby holder fitted over the transfer lever.

NATS shouldn't have any affect on the sub tank.
Do both fuel gauges work correctly?. Does the light in the sub tank switch come on when pressed?, Does the warning light come on in the dash?.
Do you have an engine shut down timer fitted?
How long ago did you fit the Sony head unit? Did you reconnect the sub tank switch? Does the sub tank switch light up when the headlights are turned on?
If you really want to bypass it, you can just use an on/off switch but you will need to remember to switch it off before the pump runs dry.

Hi Yendor,
So both tanks gauges appear to be working properly on the dash, and the sub light is illuminated with the full tank.
The sub switch lights up when the head lights are turned on.
I do have a timer fitted.
The Sony unit was in the car when I got it, and all has been working well.

If the main tank is above a 2/3 full, fuel will not transfer.

Check for power and earth at the transfer pump.

Which light? The light in the switch or the light in the dash? Does it only light up when the main tank is full?

The "sub" dash is illuminated, and the back lighting of the switch, when dash lights up. There's no transfer light at all.
