I'm using a Stewart Warner universal fit sensor and fabricating an attachment to ZR-1 sender assembly. It's a modern thick film design. I get them from Summit Racing. Number SWW-439363-D. $37.
Mark,
Could you give us a little more info on what has to be customized in order to use the Stewart Warner sensor? Maybe a photo or 2?
It sounds like you have worked out the problem quite well.
