I am removing solder from joints of left side VL tank to remove the casing (tube) the oil primer pump mechanism goes in. I have tube unsoldered at top and bottom of tank, but it is still secured at the oil/gas seperator plate. Apparently the divider panel which seperates oil from gas compartments is soldered to all four sides of exterior from inside, so how do you or which exterior panel to you remove first. What is the order of disassembly? Any helpful tricks. I am currently using a propane torch to remove solder and had tank cleaned at radiator shop. Thanks!!
