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

If it is a proper metal the stand off are the best way to go. Most people will go and pick some brass fittings and they will fail 100% of the time.
Proper quality hose will work. Proper quality stand off will work also. The Porsche PN Clay shows has worked over 1,000,000,000 of accumulated miles. It will work, if the threads match up. Could also have one machined up with the proper thread, I would do it in steel just to make sure it was positive and good stable platform. Aluminum could be a good fit if the proper alloy is picked. Not an AL expert in alloy mixes, so I don't want to recommend the proper allow mix. I will say like anything you need to check this stuff, it is never a just install and forget it. Anything that takes pressure over repeated cycles will have an element of failure. |
