Just received my ebay.uk beer engine and of course there is a problem. Pump itself seems to pull vacuum (put finger over inlet and felt resistance), but every fitting on the outside of the cylinder (including the part that screws into the cylinder itself) is broken. Sheared off right at the cylinder.
So, I am looking for anyone who might know where I could buy replacement parts. See below. The part on the far right in the pic should be attached to the cylinder, but it sheared off. The rest is what I gather is the correct order of assembly
