Oil Pressure Gauge/Sender on 4D34T

[aschafer14]

I'm looking to add an oil pressure gage with an 1/8" NPT sender and am trying to see if there are any open ports on these motors. It looks like there is a 3/8" NPT plug on the oil cooler that might be an option or I could always T-off from the stock pressure switch. Any other option out there?

I could always T-off from the stock pressure switch

I have done this numerous times in the past, as it is normally the simplest option.
Be mindful that most Tee pieces are made of brass, which is potentially problematic in a high vibration situation when there is a bit of weight on it (ie... the sender unit)
The male threaded section, that goes into the block, is generally the weakest point and the most likely point of failure. As a Fitter, I negate that issue by making my own fittings, normally out of stainless steel.
