Oil Galley Plug Removal

As noted above, take a cruddy 3/8" extension - the one your cousin Louis left in your garage will work nicely - and grind it to fit.

Thanks for the suggestions.

I actually have a cousin Louis lol.

My toolbox does not have any chisels or other items square in a close enough size. A piece of bar stock from the hardware store like the quickest bet. Same for round stock to drive the galley plug out from the sender unit passage that is under the #5 cap.
