I know I have seen a discussion of this before but I have not been able to search and find it. Can someone point me to a previous thread or explain how to remove and install the tube.

First check to be sure that the heavy wire clip is not around the base of the tube clamping it to the nub on the end of the starter motor.
The grab the tube and wiggle/rock it, moving in a circle while pulling up on it.

I tried getting mine out by clamping blocks on with hose clamps and tapping on them. That did not work so I ended up tapping it out from the bottom with the oil pan removed. I would have left it in place but in my engine it blocks access to a core plug.

Roy, I am referring to fill tube not the dip stick tube.

nvonada, I assume from your response that this tube is just a pressed in piece. No type of clamping bolts or clips or clamps, etc.

I made a tool to use a slide hammer to pull the tube on my Model A. If the tube on my Studebaker is the same diameter, then it should work for that also, otherwise I can make a different size plug and clamp.

They are pressed in. What should work: find a piece of round stock or heavy wall pipe that will just slip into the top of the tube. A large socket should work. Insert that in the top of the tube, to keep the tube from collapsing or being stretched beyound its elastic limit. Clamp a large pair of Vise Grips on the top of the tube, and tap on the underside of the Vise Grips with a small hammer. May leave some jaw marks on the tube, but it won't be crushed or distorted.

The only thing that worked on my 169 was turn the engine over, remove the oil pan and put a socket in the tube hole then beat on it with a BF hammer. It finally came out. It seems like some of those fill tubes were inserted with a light press fit and others with a HEAVY press fit.

I took this picture of a beautiful 51 Champion at the St. Louis National meet a year and a half ago.
I wonder if the owner knows his oil fill pipe is installed backwards?
