I will try this again since it didn't seem to go thru last night. Hi, my name is Jerry. I am new to the gas pump hobby. I just acquired a Tokheim model 600 visable gas pump. The bonnet and top plate was easily removed as it must have been removed at some time previously. I removed the six bolts underneath thinking that the ring that the 12 vertical rods go thru would loosen and let that part and the glass come off. It would not budge. The glass is intact so far. I am not sure where to go from here. I read the thread about removing the glass using brake fluid or WD40 and a pick of some kind, but that seemed pretty vague and did not mention anything about the cast ring that the rods go thru or how to remove the tubes inside the glass. Please help and be specific if you can about this model pump. Thanks, Jerry H.
