Can I pull fuel for my Nitrous Outlet kit from a 1/8" Gauge adapter?
I there a limit to how much I can safely spray pulling from a port that small?

something like this

 

Do you mean a manifold? If so, that's the part we use on our plate systems made for aftermarket rails. Where are you wanting to pull fuel from?

 

That's what I am looking to do. Its going to go from an aftermarket rail.
Wasn't sure this would flow enough or if I would have to go with a 3 port Y adapter to go to each rail and then to the Fuel solenoid.
My kit was originally for a 90MM plate but I switched intakes and am going with a stinger plate.

 

You shouldn't have a problem pulling fuel from there depending on how much you're wanting to spray. Nice choice on the Stinger! How much are you looking to put through it?

 

200-250 max. Its a pump gas car.

 

Also wondering the fueling limits if supplying the fuel solenoid from a fitting similar to above.

I have an NO plate kit for a FAST intake on a G8 (needed the top nozzles on the plate), and have aftermarket rails.

 

250 should be easy if the pump is adequate. Look at the recommended jetting compared to 5 years ago. You used to see 63/36 for 150 hit, now a 36 fuel jet is recommended with an 82 nitrous jet. That's 250 per nitrous outlet's jet chart.
