Jim K, I have absolutely no idea about whether or not the VW parts could be made to work. Sorry... I don't really know VWs that well. What you may want to consider is measuring the resistance of your fuel gauge and seeing if you can locate a VDO or AutoMeter fuel gauge that will work with that range. Those aftermarket gauges will have their own, internal voltage stabilizer.
However, (and this is a big however) the sender resistance on early, non-stabilized systems went from high ohms on Full to low ohms on Empty. The later sending units deliver high ohms for Empty and low ohms on Empty (opposite). I've never considered doing this... but I suppose you could open up an old sending unit and invert the tube around which the resistance wires are wound. This would make the sender work in a manner that's compatible with bimetallic gauges. However, you'd still need to buy a gauge that would work with the output range of the Smiths sender. Later Smiths gauges won't be set up to work with the resistance range of the early senders.
