I used copper tubing that goes from the gauge on the pillar pod through the firewall, then across the firewall and down to the port in the block where the idiot light sender was originally. I used a metric adaptor kit which goes directly into the block, and then the stock fitting and line goes into that. I have found no leaks. Gauge is new.
I just started it up to check it again. After about a minute, the pressure is about 40psi, but drops to about 30 after idling for a while. Not long after that, it drops to 0.
The idiot light never came on before. Oil is full...10W30 There is only about 20K on the new oil pump and engine. Should I have the oil pressure checked professionally?

Thanks for the replies,
