Thanks guys yeah, id sorta resigned myself that a drum out job was the only way , but, had to ask, yeah very silly design, im guessing the pumps usually are very reliable usually so the location of it didn’t matter,I’ve no issues stripping it, just a flippin pain with Arthritic fingers what do you mean fiddly to change the pump? does the motor have have to come as well to access it? i mean the pump does pump…!, but its very very loud lol, odd is, when its pumping you tip the driver backwards, or sideways , on two feet , the noise stops, but as soon as you pop it back on all 4 feet its there, i think tomorrow ill swear at it a fair bit then attack it on Monday
