Max, didn't you have a PS2K kit??? or am I thinking of some one else???

just get yourself a pressure switch, one off of a water tank will work if you dont care what it looks like, set it to make contact ot 5 psi, no more 'pane below 5 psi.

again, if ya want another "volunteer" I will test one out, dont know many people that can run there truck as hard as me, (maybe its cuz the bank owns em)
I will put it to the riggors.

on edit, is it a variable feed, or on/off. and is it all vapor, or liquid to the engine bay, vapor after that??? or are you not allowed to coment on it yet for testing reasons???
