Tim I do believe your are correct. Just went out and took a look at the '50 and the '54 and both use that double compression nut. That is the same type nuts that are used on the cross-over oil line that passes thru the water jacket on the early engines cept these are 1/8" instead of 3/16". The back of the oil gauge is machined to take that kind of a male compression nut. There is a matching double compression connector that is used on the oil lines.
These are kind of hard to find as anyone that has spoiled their cross-over oil line can tell you.
This type of compression nut normally is a one time shot. Once the nut is tightened down it pinches it's tapered end down on the line and usually you twist the line when you try to back it off.
I suppose the reason they didn't use the Nut & sleeve type fitting, which can be disassembled a few times, is because the connection was only meant to be a one time shot not something that would be assembled and disassembled many times during the life of the vehicle. Which was only meant to be about a decade.
Now, how did you find that in their online catalog??? Every time I try to find anything like that on any of the auto parts catalogs they all want the make and model of the car or truck and I can never find anything strictly by the part number.
