Hi,

A scuba tank will _not_ work, it's made for compressed air (which is in gas
form in the tank). Nitrous oxide is liquid in the tank. Getting a new NOS
tank is the best option.

You can get the fuel anywhere between the fuel filter and the CIS box.

As always, start with a small shot to make sure that everything works. Get a
fuel pressure switch that turns the system off if the fuel pressure drops. A
WOT switch is also a good idea.

You'll also notice that the fuel pressure in our cars is very high, around
80psi. But note that going from 40 to 80 psi _DOES NOT_ double the fuel
flow. The formula is: new flow= sqrt(new pressure/old pressure)*old flow.
The orifices are marked with the diameter of the hole and the flow is
related to the area of the hole. Feel free to ask if you have problems
calculating the right nozzles, it's easy to mess things up.

Jörgen
