I think they go near the end cap, but your 2nd question is a good 1. I would figure if you got the fuel on the fan, it will catch fire when you shoot, rite? Maby this is were a injection system come in???

Build a injection system, screw a 1/4" nipple somewhere in your chamber, that way you have direct injection. I'm no expert by know means but from what i've seen around here, thats the way it's done.
