Pressure Sender 5-Bar [VDO] [360 001]

Thread 1/8"-NPT (National Pipe Thread).
Earths/Grounds through sender body.
One terminals :

   500-Kpa  ||  5-Bar  ||  75-Psi
   Standard VDO sender to match most VDO gauges.

If you require a  switch I would suggest a tee-piece setup like so :
Part numbers :   [230 031]  ||  [360 001]  ||  [70510]

HEX Code : 29/41 or 29/4 (This is the abbreviated part number on the hex-nut of the sender.)
