Stage 1 V8

I want to fit an auxillary tank to my wagon.

I get the basic idea of the factory unit but haven't seen or been able to locate one to inspect. Would anybody have a copy of the factory instructions? Or otherwise be able to take some pictures of theirs?

I have the instructions for the 4/6 cylinder but am chasing details of pipe work, fuel tap position, fuel return etc. for the V8.

On the same thought, does any one know if there is a 'top fill' version of the larger Australian side fuel tank?

When you say you want an auxiliay fuel tank, are you referring to the rear tank?

Its a wagon, so rear tank is standard. The factory optional tank is a top fill unit fitted under the passenger's (LHF) seat.

Some of the military (LWB) versions appear to have two front side tanks in place of a rear. However these are external fill.

Oh right. Haven't seen that around.

My FFR has one under the driver's seat and one at the rear. The filler pipes are both on the right.

The vehicle batteries are located under the passenger seat.

How does it control switching between tanks and fuel return?

Switch on the dash, with two fuel pumps, etc. Quite good really, you have a redundant system in place in case of them fails

I don't suppose you could take some pictures and e-mail them to me? You may have a local variation.

The way I understood the factory system was a; mechanical tap with electric switches, one pump and some type of solenoid operated tap to switch over fuel return.

That was only on the standard series vehicles, II and IIa for example.

I'll see what I can do about photos.

Hey Map

My Stage One has an auxiliary fitted under the passenger seat with a fill on the near side guard.
I use the auxiliary to pump across to the main tank when it's empty.

Hi Mark, that is correct for the factory civilian models, as per the parts manual, but most stage 1s in NZ are ex army, 24v which had a setup specific to them.

Would you have any details of the NZ Army arrangement? I don't mind the idea of two pumps but there still must be some one way valves or solenoids in the system.

Thought of this, however I have a wagon. So I either use a top fill tank or come up with something like the Army command vehicles.

I had planned a system like yours but kept getting caught with issues like automatic pump shut off and plumbing. I would rather be on one tank or the other so the factory system still came up trumps.
I haven't managed to get the Commonwealth to donate the electric fuel tap from a 110. As these switch two fluid circuits at once.

Not 100% sure on the NZ army system, mine wasnt complete, but the parts book for the 90/110 shows a system that uses two pumps and one solenoid for switching the returns. It was used on later vehicles with in tank pumps.
Its something I will look into more when I build my hybrid, havent worried about it with the 110 as it has LPG and petrol.

Thanks, I will look this up. The only 90/110 listings I had studied were for traditional carb arrangements. I hadn't thought to look at later models with in tank pumps.

Hey Map.
Mine is a wagon also.
Pump is just an in line peristoltic pump I think.
Capacities are similar in sub tank to main tank.
Leave the sub a little short and pump over when needed
