Auxiliary Tank

[rafa]

Hi. Just wondered if there is an easy way to check if aux tank is working. On start up the dash light comes on. Put when running if if I press the dash button for aux tank no light comes on.

Cheers.

Marty.

What sort of car you got mate????

[macca86]

If you are new to patrols the sub tank transfers to the mAIN tank once main tank is 3/4 full r less. So once your main tank is less than 3/4 press your sub tank button light will be on and watch sub go down and main go up

Thanks Macca. Does 12 hours count as new? 02 4.2TD ex Telstra.

Cheers. Marty.

Aha yeah that's new. It ad me stumped too with the sub tank. If the sub tank light in your dash comes and stays on that means there is a fault with te sub tank. Also in diesel meds every time you start up it will transfer for 10 to 20 seconds so don't freak out if the sub goes dwn without touching the button

Ok so with standard tanks at 110km/hr what a realistic range / consumption with the pod loaded. I've hit the button and the sub tank seems to be going down faster than the main is going up if that makes sense.

I am pretty sure that the main tank is larger than the sub tank, which makes it look like the gauge isn't moving far.

What size tanks do you have in your Telstra Ute?
Is your main tank full at the moment? ( That may explain why no fuel transfer, but the light should still work ... )


Cuppa has an ex-Telstra Ute, and he may be able to shed some light on what his has as standard.

Not sure of tank size yet for main. But got 80 in sub when gauge was empty.

I pressed sub button when main at 3/4 tank now sub nearly half tank and main nearly half way between 3/4 and full. And have only done 210km since filling both. Light load in pod and 40 km city running around then on highway 100-110 km/hr. seems like a lot of fuel 32238

Marty,

From standard main is 95 Litres, and sub is 80 Litres for the ute only.

Should use somewhere around the 14 - 15 Litres per hundred on the highway, so theoretically, you should see over 1200 K's from both your tanks .....

[rafa]

My gauges look like this after 235 km is that normal?

Only if you have pushed the SubTank switch, otherwise the Sub should still be fairly full. The Subtank pump will operate every time you turn the key, for around 10 seconds, I guess to keep it lubricated and primed, so you will lose a little out of the top of the tank, nut with 80 Litres in the sub, you would expect the gauge not to move.

When you filled up, was the Sub Gauge full?

[rafa]

Both were full when I left. I hit the sub tank at 3/4 on main. Just eems a lot gone so far if your thinking 1200 for both?

[threedogs]

Plus re using sender from 35 ltr sub don't assume half is half. When fitting Aux tanks they make sure only by using negative off. Meaning don't take half as half full
After a while you get to know roughly how much is in each tank.

If you filled up completely, you should have around 170 Litres, so even at 17 Litres per hundred, that is 1000 K's to the tanks.

My long range tank in my wagon is as such that when the low fuel light comes on, I still have well over 20 Litres left in the bottom.

Yours may be similar, and you will only know when you refuel.

546 km for 86L fuel used on that trip.

A/C on and prob averaged 105 km/hr on highway.

Really drove it carefully. Thought It might go a little better on fuel. But it's better than the F 350 I replaced :)

Thanks for your input.

Marty.

Noticed my fuel gauge for main tank is slow to drop until a third/half full then drops quickly. Was the other way until a better earth for dual battery was fitted.
I have canopy which sits higher than Telstra pods and I get 13.25 to 13.75 lt per hundred klm unfortunately on bitumen to and from work with no real weight on board.

[threedogs]

@ rafa that's 15.9/100, thought you should be getting a bit better than that

edit just noticed you had 4.2 td I'd say that's pretty good from a big 6

[rafa]

Well I'm doing another big bush trip next week.

Should I go to Repco and get injector cleaner through it?

Will also change air and fuel filters to see if that helps.

Thanks all.

Marty.

[macca86]

That's about right for your fuel consumption 14 to 16 l per 100 is what td42 get. You can get it tuned and get better economy. Zd30 patrols get 13 to 15 l per 100. It's close to 3 ton and a pod is a parachute so not bad if you ask me

[rafa]

Yeah Macca. Prob got more in there than I think too!
