Fuel ?

Hi Penguin, i forgot to mentioed as soon as i crossed back to NT " Alice Springs" it went back to filling to only 69 and has been the same in all other states as well as New Zealand i thougt that it might have been heat as the truck is mainly in New Zealand in the summer but have had some late hot weather in Qld since we have been home and still 69 not sure what they put in it in WA.
Puzzled

Hi Desert,
Yes i am aware of that and do fill both tanks however one can never really tell how much you have left in the main tank because of what you have said, the point is that when i fill my reserve which is not the standard reserve as issued by nissan but one made by loneranger as i said when it was first filled it took 80 Litres and i have never been able to get 80 back into it and i accept that it keeps some in the tank after it shows emty and will not pump any more i have tried to pump down hill uphill you name it, i am not questioning my calculations or the the reading at the pumps, however each time i filled up in WA it takes 89 L now i think that is strange, could it be that WA measurs are different to the reat of Australia and New Zealand, i wonder what would happed if you never filled the sub tank. When we fill we always fill both tanks and take a note of what went into the reserve i could understand if it was just the odd pump, like once in NZ it took 91 Litres when i went to query it with the manager at the station it nearly caused a war.

Sorry desert,
Should have read 70 Litres for WA and 60 Litres for the reat of Australia

I'll get this right in a minute 79 Litres for WA and 69 Litres for the reat of Australia,
Tme for a power nap

I dont think i can can i ? as in the Patrol you only ever run of the main tank and the sub emtys to the main tank. I thought that it was somthing to do with the hot weather and expansion as well but after the last trip to NZ we even filled up 2 degrees one day and got 69 so i just dont know what it was.
Atmosheric - pressure well now thats a thought would that have anything to do with it being dry and not humid.

Yes true the patrol’s do draw from the main tank I thought because you put an aftermarket tank on it may have been set up to draw from either of the tank’s.

Generally WA has higher atmospheric pressure than the east (I think). The higher you go the less pressure and if you have a low-pressure system and you are at altitude alpine areas in New Zealand for example it is possible it could have an effect. 10Ltrs deferens compared to WA very unlikely.

Perhaps the fuel gage is playing games. Try just forcing 80Ltrs into the empty sub tank see how much goes in before it start’s coming out the filler hole.

If you fill up early in the morning when it is still cold you will get the same amount of Litres but you will get more fuel as the specific gravity of fuel is at it’s lowest .79 from memory. Sorry didn’t explain that to well

Phew that one has gone right over my head as well, and i have had my nap, tried that seceral times fill slow shake truck fill slow again still only 69 i am not that worried about the 69 i can accept that i have 10L in the tank that i can't run i just can't get my head around the WA thing but have to take a short cut to the Alice this year via Broome to find out for surem glad i had the handbrake with or she would have thorugt i was ready for the chair and telly.
Thanks for that
