Aftermarket VDO Gauge and Sender is a direct replacement for the expensive 0015424705 CAPILARY TUBE original gauge. Conversion uses a more common and less failure prone sending unit that screws into the cylinder head. Gone are the days of kinking or breaking the fragile capillary tube on the original gauge. Comes with all connections, gauge, sender, and instructions. PRODUCT UPDATE: We have a new source on these 24V gauges with a major price reduction.
