I have seen far more ghetto guns in my time, this is very resemblant of my first cannon, which didn't have the advantage of measured fuel.
Be careful having the igniter in the cap, as this is a weak point already (pressure wave meets flat surface) and it's certainly the most common blowout I've seen.
