I'm not familiar with the compost injection equipment, although my husband made a venturi type bubbler for our aquarium that works on a similar principle. It looks to me like you have a 1/2 inch T side piece rather than a 1/4 inch side piece. This may mean that the hose water will find it just as easy to go down there as straight across to the injector pipe. I think this side pipe does need to be smaller in diameter to produce the pressure difference that will suck up rather than blow down.
I think you have a compression joint to the compost tap, so maybe it would be possible to add a constriction between there and the T-piece without having to start again. - I'm thinking some flexible thick hose pipe material could be pushed inside to reduce the diameter and that would be enough to see whether it might help.
Sorry - lots of thinking and not much certainty for you, but it may be worth a try.

How much space should there be between the garden hose line and the siphon tube inlet?
