ok thanks hun,
still that part No. is what you want to fix your reg leak,
i think these seals fail due to running a knackerd reg/acum sphere for to long, so the clicking jar's the hole reg which kills the O ring
whats left of finger is doing fine, its the next one along which is still quite swa finger, as i took all the skin off the inside face right down to the grissle between the two knuckle joints, so the new skin is still very thin (silly me),
bandages came off on friday
