Welcome to spudfiles :)

Nice "standard" launcher, shame you went for the "garden hose nozzle" type pilot valve though. Replacing it with a ball valve (which could also incorporate the fill valve) would greatly reduce your pilot volume, improving performance.

Also, you'd be able to take advantage of the all-metal construction and go to higher pressures.
