Hello members, need some help on my G&B T176 visible pump. Can't get these fill and overflow pipes out and I don't know if they are just pressed in or? Think their to thin for threads. Also on the bottom side of the jar base is a small pipe that looks like it was held in with two bolts. It's also stuck and I don't know if that is just pressed in also? Thought I'd ask someone befor I start digging into it. Don't want to hammer on anything. Any help and knowledge is very much appreciated.
