The gas tanks are interchangeable but you may need to also change the filler
neck. There was a smaller and a larger diameter one, I know that there are
two sizes of filler neck to gas tank gaskets. I'm not completely sure that
the actual hole in the tank isn't the same though. Also, there is a
difference between the early tanks and the later tanks on the outlet tube.
The early tanks have a small diameter tube that matches up with the small
diameter of the inlet of the plastic square low pressure fuel filter. The
later tanks, and the tank that VW now sells as "universal", comes with the
larger diameter outlet tube that matches up with the larger diameter of the
inlet to the fuel pump, also matches the diameter of the outlet of the square
fuel filter. If you use the later tank on an early Van you will need to
fabricate a reducer fitting ( I turned one on my lathe for my '84) or you will
need to convert to the later arrangement where you have the fuel going
directly to the pump with the high pressure fuel filter (metal can type)
downstream of the fuel pump.
The current fuel tank that VW sells (very expensive, and do I feel stupid now
that I know the Bus Depot sells one at 25% of VW's price!) has plastic tubes
and plastic screens internally where the old tanks were all metal inside.
Maybe Ron could comment about the internal parts of the aftermarket tank he
sells. I think the metal tubes and screens are a better idea for the long
haul.
BTW, to another poster concerning how to clamp fuel lines, I use a little pair
of locking pliers (vise grip type) with a couple of 1 inch long lengths of
rubber hose slipped over the jaws to preclude cutting the rubber line being
clamped. Works very well, causes little trauma to the fuel line.
