Is anyone able to tell me how to stop my GU's anoying habit of transfering fuel from the sub tank to the main everytime the engine is started?
It gets anoying if you're doing a fair bit of stop and start on a weekend and end up with bugger all of your reserve fuel left.
Is it possible to set it up so that like the Cruiser, when the sub is in use it doesn't transfer the fuel, it uses the sub tank instead?

Turps if you read your handbook it tells you somewhere that on start-up the transfer pump automaticaly pushes .5 of a liter across into your main everytime u start up, supposed to have something to do with keeping the system from clogging up as most of us would just run out of the main all the time & leave the sub for later thus leaving it open to algae problems and the like. But it is a bit of a pain in the ass?

Gee, .5 L at every start... that must mean about 60 starts. What's the difference, you still only use the same amount of fuel, it's not as though it's wasted or anything. Anyway, just means you don't have to push the button as early as you would have to otherwise.

I understand that its only 0.5 litre but you'd be surprised how many stops and starts you do in a weekend, it gets to the point of not knowing whats in your tank. I guess I'll just have to go and visit an Auto Electrician and have him change it.

I always use the sub tank first (non patrol though) as I don't consider it a reserve supply, merely an additional tank.

Hi all, i have a Gu, i think the hand book actually says the pump runs for 10 seconds, that would not amount to half a litre, it takes about 20mins to transfer the 30 litres to the main tank. It is designed to keep the pump in operating condition. cheers Michael.

I put up with the 10secs of pumping every time I start the wagon up. Long trips no probs, round town annoying.
But what frustrates me is why the diesel has about 5 litres less capacity in the aux tank than the petrol (advertised diesel capacity 30 litres, petrol 35 litres, originally 40 litres when released in 1998). It's exactly the same tank in each model. A couple of years ago, the Nissan tech support line guy tried to tell me that he thought diesel takes up a different amount of space than petrol!
Sometimes I can only get 29 litres in it. Not much more than a Jerrycan!
