Quantum Technologies in California manufacture a line of gaseous fuel injectors.
You will have to contact them to find a distributor.

Liquid propane injection, it can be done but simpler is to let the LPG
transition to gaseous state and control from there. Pressure is a little easier
to manage, plus you get better mixing of fuel and air.

However, from the sounds of it, you are not necessarily interested in ultimate
economy or emissions.

Good Luck
