Here is another item I was somewhat concerned with. It is interesting to know this tank is actually two separate tanks housed in one unit: Gasoline and Oil. Another interesting fact is the tank assembly is made of copper, which means there will be no rust inside to deal with. But the concerns I had about the tank consisted of leaks and mounting screw hole (7) threads and leaks. I was able to run a thread chaser (10-24) into all seven mounting holes (three on top and four on bottom). Also confirmed all seven threaded holes did not leak into the tank assembly.
The inside of the tank was “dusty”. No visible corrosion or old gas seemed to be present. I filled up both chambers with mineral spirits to “wash” the inside and let the tank (with petcocks closed) on a clean piece of cardboard for two hours. Glad to say NO LEAKS!
I then cleaned up the two petcocks and confirmed they were in good working order and the flow of gas and oil was metered with the threaded petcock needles.
I then filled both chambers with acetone to rinse the tanks and again check for leaks using a thinner liquid. Nothing. I am thrilled! What this all means is now this tank can be stripped and I can paint it with a spray can of black paint………..NOT!!!! This tank will stay as you see it, 100% unrestored original!
Also interesting when I did my final flush and blow dry on the inside, this rag blew up from the gas chamber! If only this piece of cloth could talk. What was the original garment this came from? Why was it in the tank? We will never know so I guess I will have to make something up.
Over and out for now……..
