Your fuel lines will be ok for putting around on the street.
A better setup can be seen in the pic.
Most street setups fall short in the fuel supply volume at wide open throttle.
Whatever pump setup you have, it needs to be able to maintain 2 lb or more at wide open full load throttle.
You can observe the fuel pressure with a TEMPORARY mounted fuel pressure gauge on the cowl OUTSIDE the cockpit. Never mount the commonly available fuel pressure gauges in the cockpit. Potential fire hazard.
Most "hot rod" air cleaners are restrictive. A good rule of thumb is the filter area for each carb should be at least 4 times the carb throat area.
This is hard to achieve with individual cleaners. Most hot rodders don't like the look of the modern "covers all the carbs" type cleaners but it is about the only way to get adequate area with no restriction. Here again it depends on how fast you want to go or how old you want to look.
Your variation in vacuum between the 2 carbs is probably due to the choke in only one. It will probably won't hurt anything if it is just a small difference.
