That is what I thought as well. Besides being of a smaller bore, the line
also did not have a coil in it. The only other possible explanation I can
think of is that the right angle bend to go through the fire wall caused a
pinch in the narrow bore. All I can say is that after replacing the line,
normal oil pressure reading on the gauge.

To be honest, the diameter of the feed line should make no difference. There
is no flow in the line, just the transfer of pressure.

I struggled with oil pressure that was on the low end for a few years even
though all the usual culprits checked out fine. I finally traced the
problem to the copper feeder line to the gauge. Replaced that line with one
of correct bore and the problem was solved.
