Polycarbonate sight glass

[tazuk]

no its the push fit bit that wont go in the tank conector is from tool station and the elbow is from screw fixx
the smooth push fit wont even go in to a 15mm olive :wha: nor the tank conector :wha: :wha:

Not sure if the tank connector is too small or the elbow too big. Im not at home at the moment to measure the poly tube, but I think the od is 15 mm. ie check if the tube fits directly into the tank connector s. If it doesn't then the connectors are under size.
Otherwise see if a bit of 15mm copper tube fits in if you have any.

Hope this helps identify the problem
