We're going to be making some tanks later this spring from aluminium.  (See
http://www.syncro.ca/TriStar ) Right now I am in the R+D stage of the
process and I have a few card board mock ups here at the moment.  For me
these tanks are too important to get wrong! :)

It will occupy the space between the outer and inner frame, it will have the
correct VDO fuel gauge sender, it will have an optional coolant driven heat
exchanger so that you can bring you fuel up close to coolant temperature
(good for the veggie-oil guys like me), it will hold about 60 to 70L of
fuel.

The only concern that I have is these are going to be long narrow tanks.
Does anyone have ideas on how to make a setup where if you are on the last
10% of the fuel on the tank and you go down a steep hill that you won't run
out of fuel due to the pickup being 'up hill'?  I was thinking of a small 1L
aux tank that will act as a 'capacitor' of sorts where it is situated
between the main 70L tank and the engine.  It has a one way valve on it so
when you are sucking air the engine still takes fuel from the bottom of this
mini tank - chances of going down or up hill for more than 1L worth of fuel
is remote, but, the question is, how to auto-bleed the air from this when it
does start seeing fuel again.  The only way I can see to do this is to have
the mini tank lower than the tank that you are draining from with a vent
coming out of the top of the mini tank that leads back to the main tank.
When you are back on the level again this design would make it fill up again
as the air would have a way out and back into the main tank.

Subject: second gas tank in their vanagon?

Hi All,
There was a group purchase, about three years ago,
for the extra saddle bag gas tank,
that fit under the passenger side sliding door area.
The purchase was put together by Bill Kasper, I believe?
Does anyone have any saved Pic's of this tank?
My address for the tank, is no longer viable.
JC...

 I realize this isn't strictly on the subaru topic, but has any one
installed a second gas tank in their vanagon? I've heard rumor of south
african ones... How are they filled and where are they? I'm also interested
in any other good ideas.
