Gas sub tank in GQ

Post by **create** » Sun Sep 28, 2008 4:08 pm

This week I installed a second gas tank in my GQ. Its a very tight fit and I havent installed the stone shield yet. It will give me another 49l of gas. I have got the tanks set up so I can switch between them. I also have two filler nozzles and two fuel guages.
I guess this same setup could be used for diesel gas too. You could leave the existing fuel tank and this tank.
The tank is a APA B80.

Yeah - it hangs down about 60mm below the chassis rails. With an extra 2' lift it would be great!

you look at the APA C80 tank 285 dai instead of 330 only 12 ltrs diff in holding 37ltrs but atleast it would be up inline with chassi all depends on how hard you drive the tracks just mho as thats what i'm looking at doing cheers tim

have u got the valve box mounted to low?

Post by **create** » Mon Sep 29, 2008 1:33 pm

Not sure what you mean NutterGQ? I dont think any of it is too low for what I need. I could possibly get hung up on the tank on ramp over. I only use the GQ on weekends to go bush its not me daily driver. I needed a 4WD that was more capable than my previous trashcan... I mean Terracan. Something that can tow my camper trailer and get me off the black stuff. I dont see that I will do any rock hopping. The tank should give me a range of about 600 - 650km thats all I wanted.

the box, as in the box with the valves etc etc in it. if that is not in the correct position, you will not get the right amount of gas in the tank

I filled the tank this morning from empty. APA says it should hold 49 litres. It took 47.89 litres so I think its pretty close.

Post by **tna racing** » Mon Sep 29, 2008 3:22 pm

dude we have a smaller tank than that wich holds 47liters

The top of the valve housing is meant to be horizontal, this ensured that the gauge works correctly, if will fill full because of the pressure cut off, not sure if it will completly empty dew to the pickup inside.
See how it goes.
Also what length is the tank and how did you go with mounts, to the floor or chassie.

I had to strip the whole interior from the front seats back. The mounts went in fine. Both mounts go to the floor not the chassis. The rear mount is spaced out with a piece of 40x70 box section as the floor dips up to the 7th seat. I also had to buy longer bolts to suit. Its a very tight fit between the 5 link suspension holder and the chassis brace bar.

TNA racing - how do you have a smaller tank that holds 47 litres? My tank is 61 litres water minus 20% which is 49 litres.

AndrewGQ 351 - I will rotate the tank a little more to get it horizontal. There is enough room to do it. The valve housing is not hitting anything.

Thanks for the comments . . .

look at the angle your box is on, i would have it facing up.

You need to set your valves at 30 degrees..if you do not the AFL will limit your fill.

Already been answered lol, but on that tank the box should be horizontal to make sure cut off works properly. I was going to do that same install but its pretty low and tight, might need to look at goin inside and making false floor on top.

I have added a set of whats known as scuba tanks onto the floor in mine,
they are the tripple tank that i think that they fit into station wagons.
They are a 69 water ltr and i can get 55-58l per fill.
The tank is only 220mm high and about 900 by 1000.
This still allows for a full length draw on one side and water container locations on each. the top of the floor is then level with the top of the wheel arches
I run two fillers so i can fill up both tanks at once and a single gas line out of a check valve which has the two tank lines going in.
Two gauges and switches to shut each of the tanks off at the tank solinoid, allowed me to get an extra 220-240 km per fill up

The concept is great to fit a flat tank in the back of the vehicle but I need the 7 seats and my wife wasnt keen on having a "bomb" inside the car.

Post by **ANDREWGQ 351** » Tue Sep 30, 2008 7:49 am

Fair enough about the 7 seats but a bomb inside or one underneath you i dont know if it really matters

Post by **NutterGQ** » Tue Sep 30, 2008 11:06 am

lol if it goes up the tin floor wont help you, Andrew with the scuba tanks are you talking about falcon ones?

Post by **ANDREWGQ 351** » Tue Sep 30, 2008 12:08 pm

i believe that it is, not a new tank though

Maybe something to look at their cheap second hand, build a false floor on top and your laughing.

yep, manchester or apa manifold tanks are perfect for putting under a false floor. (they are the ones you are talking about, the "scuba" tanks)

as for the tank above, the main issue you will have is being able to get to the valve box. normally the firies need clear access to the service valve to turn the tank off if they need to. i dare say (depending on where you are) it may be defectable having the valve where is currently is...

they work even better of you have a bodylift and you can sink the tanks into the floor
