So far nobody has ever blew one up, plus if you tap the pressure side of your intake then you're going to have to run more propane pressure than boost pressure or else it will just blow backward and no propane will ever enter your engine.
Think about it, 1.5psi of propane trying to force itself into a intake with 5psi running steady or 35psi going up a hill??
Feel free to not use propane, it's not for everyone that's for sure.
