oil pressure -gauge question

[brads70]

I'm in the middle of hooking up my new Speedhut gauges and the oil pressure gauge is not reading at all. I have an Autometer mechanical gauge hooked up on the passenger side pipe plug location and reads oil pressure just fine. My question is does the other side  ( pipe plug on drivers side) also hooks to oil pressure right? That's where I have the Speedhut sensor plumbed into. This is a 400 block.

yes both plugs at the rear connect to the oil passage but have different thread sizes

Thanks I was pretty sure just thought I'd rule that out.

It would be unlikely, but could the driver's side passage be plugged?
Power to oil gauge verified?
Double check wiring connections.
Correct sender for a gauge? Different one than for an oil pressure light that your standard dash came with.

I contacted Speedhut and they gave me a bunch of things to check. I'm not getting the 5Volts coming out of the gauge that I should. I'll double check my connections this afternoon but I'm pretty sure I'm good as the other gauges work fine. I'm leaning towards a defective gauge?  Speedhut provides the sender and wiring harness.

Gauge was defective. I sent it back last Wednesday to Utah, it's supposed to be back here tomorrow.
