can some helpful people help me finish plumbing in my RST conversion

i have these three small unions to connect up

the air hose to the actuator and the union on the turbo housing - both seen in this pic


and this pipe on the metering head



do they connect to the amal valve? i don't think i have one what does it look like.


could someone also have a look at these and check theres nothing glaringly obvious wrong
