I recently noticed that I had a leak in my steering box. Came to these forums and went to the Hoye site to view their YouTube video on rebuilding. Not really ready to go there yet. But I needed to re-fill the steering box with 90W gear oil. The best way I found to do it was to use a #40 long-arm torx (like an allen wrench) to remove the plug. Then I used an oil can pumper with a flexible neck to get into the narrow space. That worked a charm to refill without buying anything new (for me anyway).
Hope that helps someone
