1973 Porsche 914 2.0L. I’m removing my Oil Temp Gauge and installing a Oil Pressure Gauge. I installed a 100 psi VDO Oil Pressure Gauge. Do to the size of the new Sender Unit that fits a 100 psi VDO Gauge you cannot just insert it in the same location in the Taco Plate! I was able to drill a 7/16 hole in the same plate and install the new sender unit. I left the original sender unit where it was at and just removed the plug and placed it on the new 100 psi Oil Pressure Sending Unit. On the other end I just plugged the original harness back in the same 3 prong plug in on the back off the new VDO Oil pressure gauge. Sending unit wire to G and the + to fuse box etc. No reading on gauge! What’s wrong. The new sending unit is extended about 1/2” inside. Any suggestions. Thanks

Could there be a problem with not getting enough oil to the Pressure Sender in that location? I’ve ran all continuity test on wiring, all seams good. New Sender and VDO gauge.

The place where you are hooking it up is meant to read oil temperature. In order to read oil pressure you have to tap into the oil pressure sender unit that is next to the distributor. In order to do so, you will need to get a pressure hose installed into the hole and an extension because the sender doesnt fit in the original hole. Search pressure sender extension on here so you can see. |
