 Hi frankI have done something like that for my prop shaft seal oil filled compartment.  But first i removed the hose and filled with a serynge with long steel needle. Then put the tube and filled it with the serynge. The tube is flexible and transparent, from endurance sport platypus drinking bladder
Works wellRegards Antoine

Hi All I have been talking to Rick about motor compensation which has got me thinking. I originally did my motors like other psubbers have done with the rubber tubes around the sides, but have found them a real pain to fill.  Problem is the location of the tube, plus the tiny bit of protruding pipe nipple on the inside. So, I modified the motors by drilling a hole in the top part of the aluminium endcap and use that now as the vent\final fill.  Its better, but still awkward. I have suggested to Rick this idea, which I am tempted to adopt myself.  Blocking off the existing side mounted pipe nipples and filling\venting\compensating all from the one top hole.  There would be a rubber bulb of some sort on the end of the pipe.  2x pictures show filling and operation.  Appologies for rubbish drawings, im at work. What does everyone think?
