Fuel tank

1

Hi all,

For those that have fitted the tanks from SA recently, do any of you have the middle row seats? I just put the tank in position to prepare for fitting and thought the mounting brackets were the wrong size.

The tank however does not sit hard up against the floor. There are 4 bolts/nuts for mounting the middle row seat that the tank sits against instead of the floor.

How have you worked around this?

Ideally there would be 4 notches in the tank where the nuts are, but will be a big job to do that now.

Richard,

My mechanic installed mine as I was too scared to drill large holes in my syncro - its ok if I dont see it happen (kind of like the holes were already there).

Mine sits down a bit but I have the more rectangular tank without the tapered base.

I know I have the bolt mounts under there but no middle seat any more so he didnt have an issue.

Cheers,

Skot

If the nuts are still there (welded to the floor from the factory), the tank has no choice but to pull up against the nuts which would not be a good way to mount. If you don't have the seat, could they have removed the nuts?

Alternative would be pack the tank down to miss the nuts, but this would meant the brackets are now short.


Yes I have the larger tank, clearance still looks fine as it's above a lot of other things under the bus. I did not get this one for the extra capacity, I got it for the tapered side. I had some made for my T2 years ago, basically the same as these. What I found with the flat bottom is it leaves a lot of fuel left in the tank when the transfer pump stops sucking. The hope if the taper will limit the amount left behind.


I will see if notching the tank is practical before I proceed.

Hey Richard,

I have noticed that fuel is hard to get out of the bottom of the reserve tank unless you are going up a hill as the outlet is at the back of the reserve tank.

So turn on the pump just before a long hill and off once at the top - this method gets most of the last bits out.

Not much help on the Nullarbor though...

Cheers,

Yes, that's what I did on the T2, just wanted to get away from having to do that. I tended to only use the spare tank for trips and leave it empty otherwise, so didn't want to leave lots of fuel left in there.

The best idea would be to have a little collection point around the suction like most factory tanks would have. Easy to design in to let fuel drop in and hard to get out, but is just more time and effort in manufacture.


Oh, and I have also got a factory (2WD) filler now I can mount as the fill point to make it look more original. The next thing I need to sort is how to use the EFI pump as the transfer pump. Current thinking is run the pump through the stock pressure regulator, so have I effectively always have a spare pump and regulator. If it works, I can fit a pressure switch in the line so I know when the spare tank runs out of fuel also.

I am hoping a stock oil pressure switch will work fine with fuel running past it, then I have all factory parts.


In the T2 I just went off time, I knew how long the pump would take to transfer the fuel (and double check by watching the fuel gauge) and turned off after that time. Just becomes hard to manage if you do not drive far enough to transfer all the fuel. I am hoping if this idea works it will be easier manage.
