Quick nitrous fuel pressure question

if your making a tool...for fuel side....if i recall correctly...i made my jet holding tool
by taking a flare nut fitting off of the brake master cylinder ..(the male fitting that attaches the hard brake lines on mopar brake master cyl. ) i had a left over/extra fitting .that fitting will accept the no2 fuel pill and it will thread onto the braided fuel supply line that normally attaches to your no2 plate.
I took some standard hard brake line ...made me about a 24" long piece/section.
I flared the end .then slid the male fitting over it... then inserted the no2 fuel pill into this fitting then attached the braided fuel supply line to it..tightend it and held/aimed this at my fuel can...activated the fuel system and then adjusted the fuel side regulator to 5.5 lbs while flowing fuel back into my fuel can.....simple enough..
once set ..you remove the fixture assy tool from the braided fuel line
take the no2 fuel pill out then re insert it back into your plate under the carb....then re attach your fuel line back to your no2 plate..then tighten it.
need to do this any time you change your fuel side pill ...up or down...to make sure your at the base 5.5 lb flowing fuel pressure..fwiw..
i can take a picture of it...i keep it in my tool box at the track...simple safe and cost next to nothing....
