70 Cuda ralley gauge

I have the ralley gauges and need to know if there is a smaller oil preasure sender that will work with the stock gauge.
Thanks

There's only 2 types of sending units, one for gauges, and one for idiot lights, the gauge type is rather large, and bell shaped in appearance, the idiot light style is very small in appearance, and requires a special socket to install, using the wrong sender will create wrong readings on your instrumentation,...the one you need is SIMILAR to this in appearance

for gauges:

there are two kinds with same shape and looks... 80 PSI and 100 PSI. Both will work, just that scale will be diff reading.

100 PSI were mostly used on trucks as far I know.

Thanks for the info. My plan is to install a preasure switch to power the electric fuel pump. It will use the oil preasure port in conjunction with the sender for the gauge. That is why I wanted a small sender so to not have so much weight hanging on the fitting.

If you can try to find an OEM mopar oil pressure port splitter from the late 70s through the 80s...It's a big hex shaped adapter that will take whatever you want to hang from it...

WOW, thanks. Do you know a #PN?
