I cant be bothered to change my mk 1 henderson pump for a newer one cos it works.
But when i went to replace the perished diaphragm i needed a lie down after being told the service kit was over £50.
So what i did was get some thick compressed neoprene (£5) meant for gasket repairs and made my own. It took about 30 mins including drilling the holes.
This only seems possible on the mk 1 cos it has a flat diaphragm.
