Nano Street/Strip Systems!!
The pressure was creeping up while in the stagin lanes... But, thats why they say to keep it cool. But, as soon as I hit the gas the pressure came down to ~950 psi and stayed there.
You need to know if their pressure port accesses the siphon tube or the pressure above the liquid.
The base of the valve should have a small hole that lines up with the pressure port if it compatible.

this is a NX 45* valve...it has 2 pressure ports...as you can see there is only one port on the base, so only one of the side ports can be used with the NANO
