The biggest fear I had was that IC pipes would blow off, I'd have a fuel leak, coolant would explode.. something stupid that would eff up the tuning time I had scheduled. Looks like I was able to get everything back together properly in the end.
i think evan brought it up in another thread, take some JB weld and run a bead all the way around the pipe let it dry and you have a nice rim to keep the pipe on. that and i hear really good things about constant pressure clamps, i think there called.
