He told me the thing would work like a champ (again) if I replaced the (available online) pump, but in removing the burnt out old one I had to pull loose a plastic tube connected to it with brass compression fittings. No biggie except broke the old plastic tube in yanking on it and can't find a replacement part online plus cannot substitute either:

A. polyethylene plastic tubing found easy and cheap in any hardware shop BUT is 1/4" so just a hair bigger than the 6mm OD tube this requires.

B. 6mm PTFE (AKA Teflon) which I bought online but is just too inflexible for the brass fittings and the one tight bend tube this must make.

Anybody have a helpful suggestion? I just HAVE to fix broken stuff, cannot let it go...
