GQ longrange

Sorry, your right after rereading not enough info (I know what I mean :) )

The auxiliary tank is a after market model that has been added, the set up as it is now:- two filler necks one to the original and one to the aux, a breather line from aux to filler neck and an outlet to a transfer pump that goes in the original. From there, when I am running low on the original I have to switch the transfer pump on to pump from the aux to the original. I also have another switch on the dash that switches from the level sender unit in the aux to the level sender unit in the original so I can see how much is each tank.

As you can see this is very clustered, I hope someone can give me some advice on how to simplify things

G'day Craig,

The set-up you describe is virtually identical to that used as standard in the GU....and as far as I'm concerned it works really well. The only difference is that you have only one gauge ; switchable between the 2 tanks.....which sounds quite okay to me.

However, I understand that Toyota Landcruisers (for example) use a system whereby there is a dashboard switch which physically isolates one tank or the other. That system also works quite well apparently.

I'm not sure I'd bother changing the current system if it's actually working okay. It is nice and simple with no solenoids (I think that is what Toyotas use to switch over) to go kaput. The worst thing that can go wrong with your set-up is that the pump could stuff up.

By the way, on the GU, the transfer pump pumps the fuel back up to the top of the neck of the filler for the main tank.....open the filler cap when you've got the transfer pump switched on and you can see the diesel coming out of the pipe. Not sure where your's pumps into......if it's the tank itself there could be an issue with air lock or something (but I wouldn't have thought so).

Hope this helps......my advise; if it ain't broke, don't fix it......

Cheers mate
