Question on cleaning tanks and rebuild valve.
I Ok guys /gals /others
Just got it in the mail today. A mil spec lantern ? It is a 4 quadrant glass one ( no marking on the glass ). It had this on the bottom
US
Lantern Gasoline leaded fuel
Coleman
1952
(sorry again still no good pictures)

Tank is slightly dirty inside, but not bad. I reshaped the pump leather and soaked in oil, so it is now pumping and holds pressure. Valve seems to work. Any advice before trying to light this one up. First gass one
Also got a 200a that appears to has gasoline init. I rinsed out the tank a few time with coleman fuel and it still nasty and black inside the tank. It did light up, but the valve area get damp while in use ( might be seeping ) I can see fuel on the shaft behind the RED knob. I guessing it need to be rebuild, new seals ?? it is a 1973 200a
any advise?
