Message so the mass flow can be characterized and higher flow rates are achievable with a given orifice size. Good point in that if you dropped the pressure with a regulator you would drop below the vapor pressure. Hadn't thought that through i guess. I wasn't thinking stock fuel lines/filter rather plumbing some tubing from the tank with gas fittings. That gives you the ability to size it such that at maximum flow rate pressure drops dont cause mixed phase flow.

If you plumb from the bottom of the tank, you should be able to operate as a "blow down" system where the tank ullage is responsible for the pressure. In that scenario, the pumping energy comes essentially from the dropping the temperature of the gas as the tank empties. A heater with a wattage equivalent to the pumping power requirements would be needed to maintain contant tank temps. As temps drop the vapor pressure will drop as well. That change in temperature will therefore change the AFR.

This sounds like way too much fun... not being sarcastic. :)

While getting tires mounted for Zcon, I had this doozy of a conversation with the mechanic...

Tireguy: [looking at emblem] Is this a Twin Turbo?
Me: Well, yea.
Tireguy: Awesome! How much boost do you run?
Me: 14-15 ish.
Tireguy: Cool. On both?

ROFLMFAO
