Hello together, does anyone have knowledge about whether the aluminium pump pipes of Primus and Optimus pumps do have the same outside diameter? Unfortunately I do not have a Optimus pump where I could measure. Would it be possible to press the pump pipe of a Optimus pump into a Primus pump body? Hereby the Primus pump pipe with plastics no-return-valve at the bottom could be replaced by a full metal version. Thanks a lot for your help!
