I'm thinking it would be straightforward to plumb it with AN line. The trick is maintaining solid fuel pressure. It doesn't matter if it's 5 PSI or 55 PSI, it just needs to be consistent for tuning. Online calculators will give you fuel jet size for a given fuel pressure, given nitrous jet and desired HP level. The only issue with high fuel pressures, is that the fuel jet size will get very small to flow the proper amount of fuel. Use good filters to prevent orifice plugging.

If you expect fluctuations in fuel pressure, you'll need to install a separate regulator. Always set the fuel pressure regulator for a nitrous system using a flow tool.
