So I bought an acrylic Dual D5 Mod top for my pumps and seem to be confused with the O-rings it came with. There are 3 it seems - two thicker ones for the pumps and 1 thin one for the front display (aesthetics only) The problem is if I use the 2 thicker O-rings for the pumps I can't seem to screw the D5 housings on all they way, but if I use the thinner O-rings I can snug the housings on all of the way nice and easy and I have to really crank them when using the thicker O-rings. Are these thicker O-rings the wrong ones for the pumps, or do I just really need to crank these housings down? Here are a few pics: The pump top on the right is the one that isn't snug all the way down - and it's EXTREMELY tight as it is Here you can see the difference in the two O-rings: Here are the new packs of replacment O-rings - 2 really fat ones and 1 thin one
