I may be way out in left field here, but I specifically used a single
terminal sender for my VDO OP gauge.  My thinking was to use the factory
pressure gauge and "T" off the under the pushrod switch location and run a
custom made hose up to the top of the engine block for the VDO
sender.  That way, the buzzer system stays intact.  Do we really know for
sure at what pressure the VDO dual sender throws the dash light on?  How
likely is it to be the same as the factory switch?
