EFI fuel pump and water.

[Programmer]

Seth,
You can pump over 400 PSI with an a/c compressor--course it's getting
close to pumping fluid at that...<G>. Heck--rig this to a pressure switch
and you'd have a self regulating EFI water injection system.

>(Definitely not my area of expertise!)  But it may not have been using
R-12/134a.
