These are two different things here.  The products such as GM Top End
cleaner and the other aggressive carbon removers need fuel to burn.  The
engine will not run on them.  You're supposed to bog the engine with the
top end cleaner until it dies, and let it soak in with the engine off. 
If your tailpipe smoke screen isn't killing mosquitos for miles around,
you're doing it wrong. ;-)

The other stuff is fuel system cleaner, and they do come in aerosol cans
under high pressure which can be placed into a port of the fuel system. 
If anyone is thinking of getting this stuff (brand names escape me now)
make SURE and get one that has a fitting which fits the V8Q fuel
schrader, it's not a common size.  It's been a while, but it may have
been the Wurth product that came with the correct fitting for use on the
V8Q.  A couple of bottles of fuel system cleaner in the tank is usually
part of the cleaning procedure.  Valvoline and a few others have ready
made kits that come with the two cleaners and a small can of throttle
body cleaner.  Unless you already have a V8Q adapter for the fuel line,
don't bother with the kits, none that I've seen come with a fitting for
the V8Q.
