Charles, based on the time stamps of many of your posts, I wonder if you ever get any sleep.
Good point about the pressure effect of the filter feed, which would be noticeable whenever the pressure relief valve opens enough for the filter to flow. Probably best to tap in as close to the oil pump output as possible, which may be one reason why the electric oil pressure sending unit is located where it is. A permanent "T" at that location, with a removable pipe plug for the port to tap the mechanical gage for testing, might not be a bad idea. I think I'll add that to my "to do" list.

Are these the ports people are using for the fuel pump pressure switches also? I'd kind of like to keep the wiring for oil pressure (gauge and switch) routed together to a common point and tee a port and have both sensors in the same area. I'm probably dreaming here, but is there a combo device for the oil sender and pressure switch functions available?
Not in a single device; however there is a specialty switch for the electric fuel pump operation. It and the gauge sender can be installed in a single tee set up. This switch shuts down pump operation if oil pressure is lost. It also supplies power to the pump when the starter is activated so pump runs until oil pressure builds and closes switch contacts.
Charles, do you know who makes that switch, or do you have a product number for it? That seems easier and cleaner that adding a dash mounted over ride switch for starting.
You can go this route, but it's sort of like trying to reinvent the wheel. The set up I'm speaking of works much better; without buying an extra switch for over-ride at startup.
The safety switch we use is a Holley #12-810. Available at NAPA. If you will be using it with the original type 24-volt starter, there is some special wiring info you will need. If using a solenoid operated starter, just follow the instructions in the package.
I replaced the 60 PSI oil P sending unit with one from vintage power wagons. Instead of having 25PSI I now have 55PSI or so, gauge still wont go below 55PSI even when warmed up. I also replaced the 60 PSI guage on the dash with a working take out.
I replaced my temp gauge also and sending unit with the two correct ones from vintage power wagons, I still don't get a reading...

Added a extras ground to the dash also..
I emailed you on your site Charles.
Replied to the email you sent to my website. Please offer all the detail you can about the situation there.
