It seems if you remove the upper cage to use as a randalizer, then the hops would clog the beer tap line. You would have to keep the cage in to contain the upper part of the Hoprocket.
Interesting to see how you have connected it up. You appear to have obtained a male-male connector via eBay. What site did you get it from, as I understand that the connections are NPT rather than the usual (for UK) BSPT type?
Hi - it was from Ebay.co.uk, fulfilled by a company called Torques. If you search Ebay for 1/2 NPT male to male you should find it, they're still listed.
