Hello Paul,
Welcome to the Hobby......16% is ok for your engine but make sure you use a
cool rated glo-plug....My nephew has a .10 engine in his car currently
running on 10% nitro and the cool plug works best.

The pipe from the exhaust to the fuel tank is for a pressurized fuel system
to ensure that fuel gets to the engine no matter which way the car is being
thrown about.
The Nipple on the exhaust needs to be on the top of it and the tube from
there to one of the tubes on top of the tank, the other tube on top of the
tank (if you have one) needs to be closed.....best way is a short length of
fuel tube with a screw stuck in the tube to close it.

Pressurized fuel systems are basically like a fuel pump using exhaust
pressure to pump the fuel from the tank to your engine. You will get a
little oily stuff going up the tube, but if you have it fitted as I have
described, this will be minimized & you will not have any problems....The
engine will still run with it disconnected as you have stated but the fuel
delivery won't be as great especially if you have a car that shifts and
spins as much as my nephews car does.  This was initially developed for
aircraft use but set up properly, it can be used for cars and boats too and
to very good effect.
I have used pressurized systems for years now with no trouble, My 3
Helicopters, 2 Planes and my Hovercraft all have it fitted on their
respective engines.

Regards.......Mark
