No fuel regulator.
Mounted tank as per plans.
However, I mounted the tank and then proceded to drill a hole in the firewall for the throttle pushrod, RIGHT THROUGH THE TANK! EGAD! The problem didn't surface until the maiden flight when radio contact became intermittent and I subsequently crashed into some weeds, breaking the wingtip and cracking the fuse. The autopsy revealed a fuel soaked switch resulting in sporatic electrical flow!

Everyone here probably already knows this but I'll say it anyway, DRILL THE HOLE FIRST, MOUNT THE TANK LAST!

With the tank in the stock location, the Saito does have a tendency to load up with fuel on board, there are a few posts in this thread dealing with that issue. If it does load up, plug in a remote fuel filler and turn the engine over a few times, it will blow out the fuel.
