Nitrous plumbing A1A...??..

Officially still have not hit the button! LOL..
If i was in your shoes and was building my first Nitrous system.........well i would have built it just like yours. With all the safety i could put in it.
Then, after all the testing you can do with out pushing the Nitrous threw the eng, i would close the bottle valve, purge the lines........ arm it!!! and go make a hit! If it slows down....all the fuel side is working as intended. Now you know the the worse scenario will be the one you just made......excessive fuel...............and if every thing works right.........a cheese smile on your face.:steering:
